RESUMO

Background: Research demonstrates significant gender- and sexual orientation-based differences in orgasm rates from sexual intercourse; however, this "orgasm gap" has not been studied with respect to age. Aim: The study sought to examine age-related disparities in orgasm rates from sexual intercourse by gender and sexual orientation. Methods: A survey sample of 24 752 adults from the United States, ranging in age from 18 to 100 years. Data were collected across 8 cross-sectional surveys between 2015 and 2023. Outcomes: Participants reported their average rate of orgasm during sexual intercourse, from 0% to 100%. Results: Orgasm rate was associated with age but with minimal effect size. In all age groups, men reported higher rates of orgasm than did women. Men's orgasm rates ranged from 70% to 85%, while women's ranged from 46% to 58%. Men reported orgasm rates between 22% and 30% higher than women's rates. Sexual orientation impacted orgasm rates by gender but not uniformly across age groups. Clinical Translation: The persistence of the orgasm gap across ages necessitates a tailored approach in clinical practice and education, focusing on inclusive sexual health discussions, addressing the unique challenges of sexual minorities and aging, and emphasizing mutual satisfaction to promote sexual well-being for all. Strengths and Limitations: This study is the first to examine the orgasm gap with respect to age, and does so in a large, diverse sample. Findings are limited by methodology, including single-item assessments of orgasm and a sample of single adults. Conclusion: This study revealed enduring disparities in orgasm rates from sexual intercourse, likely resulting from many factors, including sociocultural norms and inadequate sex education.

RESUMO

Background/objective: The Multidimensional Model of the Subjective Orgasm Experience (MMSOE) has been validated in the context of heterosexual relationships, with no evidence in the context of same-sex relationships. This study aims to examine the association of its dimensions (Affective, Intimacy, Sensory, and Rewards) with the propensity for sexual excitation, rating of sexual arousal, rating of genital sensations, and genital response. Method: Sixty-eight young adults (34 males and 34 females) who were sexually active with people of the same sex participated in a laboratory task in which they viewed content-neutral and sexually explicit gay films. Regression models were conducted to explain the dimensions of MMSOE from measures of sexual arousal. Results: In males, the rating of sexual arousal explained the Sensory dimension, while the genital response explained the Affective dimension, with sexual arousal as a state gaining more prominence. In females, however, the propensity for sexual excitation explained the Sensory dimension, with more salience of sexual arousal as a trait. Conclusions: The MMSOE is shown to be a valid theoretical framework for the study of orgasmic experience in the context of same-sex relationships, with clear implications for clinical practice.

RESUMO

AIM: This study aims to examine the relationship between male genital self-perception and sexual functioning and depression anxieties. METHOD: The study included male patients who were referred to the andrology outpatient clinic between March 2022 and June 2022. Demographic data of the patients were recorded. Cigarette and alcohol consumption was also noted. The Male Genital Self Image Scale (MGSIS) questionnaire was used for the Genital Self Image(GSI) assessment, which consists of 7 questions. The International Index of Erectile Function (IIEF), composed of 15 questions, was used to evaluate sexual function. STAI-I, STAI-II, and BECK scales were used for depression and anxiety. The penis size of the patients was measured in a flask and stretched condition, and the midpenile circumference was recorded. Patients were compared with respect to GSI, depression, anxiety, and sexual functioning. RESULTS: A total of 75 patients were included in the study. The mean age of the patients was 46.69 ± 11.32 (26-72), and the mean BMI was 27.82 ± 3.79 (22.46-40.40) kg/m2. A slightly positive correlation was found between the patients' flask penis size and MGSIS-total scores (r = 0.260, p = .024) and IIEF-SF scores (r = 0.240, p = .038). There was a moderately positive correlation between the stretched penis size and IIEF-OS (r = 0.403, p < .001) and IIEF-SF (r = 0.354, p = .002). While the MGSIS-total score and the STAI-I and STAI-II scores had a moderate negative correlation, there was an advanced negative correlation between the MGSIS-total score and the BECK score. CONCLUSION: Disruption of men's genital self-perception is moderately related to their susceptibility to depression and anxiety. This situation affects the person's sexual performance and causes orgasm problems to increase.

RESUMO

Sexual behaviors play a role in the social construction of masculinity. Moreover, this stereotype has been capitalized upon by pharmaceutical companies, as well as those that sell products not approved by the U.S. Food and Drug Administration, for purposes of marketing sexual medicines. Stereotypical notions of masculinity, however, also emphasize the importance of self-reliance, which may cause some to look unfavorably upon the use of sexual medicine. Consistent with this notion, a male target was viewed as more masculine when his female partner consistently reached orgasm, unless he had no history of erectile dysfunction (ED), but was taking Viagra anyway (Experiment 1; N = 522). In addition, when his partner consistently reached orgasm, ratings of his sexual esteem were also lower if he used Viagra than if he did not, but only if he had no history of ED. In Experiment 2 (N = 711), although there was no effect of a male target's use of testosterone, social perception of his masculinity and sexual esteem increased as his "natural" levels of testosterone increased. In addition, exploratory analysis revealed that if the male target had low (but not normal or high) "natural" levels of testosterone, ratings of his masculinity were higher if his female partner consistently had an orgasm, which suggests that female orgasm served to "rescue" masculinity. Because expectations about drugs drive their use, it is important to address preconceived notions about the use of sexual medicines for purposes of enhancing masculinity and sexual esteem, as the social perception of their use is much more complex.

RESUMO

Female sexual dysfunction is highly prevalent, affecting 30% to 50% of cisgender women globally. Low sexual desire, sexual arousal disorder, and orgasm disorder affect 10% to 20%, 6% to 20%, and 4% to 14% of women, respectively. Dyspareunia or pain with intercourse affects 8% to 22% of women. Universal screening is recommended; and a thorough medical history and physical examination are the foundations of evaluation and assessment. Laboratory tests and imaging are sometimes warranted, but referral to a sexual medicine expert is suggested if the practitioner is unfamiliar or uncomfortable with treatment.

RESUMO

We explored the unique roles that body and genital image play in behavior-specific orgasm consistency, beyond overall sexual self-esteem. US adults (N = 599; 64% women) completed questionnaires online. Hierarchical regression analyses predicted orgasm consistency during receptive oral sex and penile-vaginal intercourse (PVI) with additional clitoral stimulation (WAS) and with no additional clitoral stimulation (NAS) for the woman. Body image, genital image, and gender were entered in later steps to assess model improvement above sexual self-esteem. Models accounted for age, sexual and racial minority identities, and current relationship status. Results indicated that genital image improved all models and predicted higher orgasm consistency across all behaviors for men and women. For orgasm during receptive oral sex and PVI-NAS, sexual self-esteem was no longer significant once genital image was included. Genital image was a stronger predictor of women's versus men's orgasm during PVI-NAS; no significant gender differences were found for oral sex and PVI-WAS. Body image was not significant in any models, contrary to expectations, suggesting role overlap with sexual self-esteem. Genital image appears to play a unique role in sexual pleasure beyond overall sexual self-esteem and body image.

RESUMO

Background: Up to 41% of women face challenges achieving orgasm, a statistic unchanged for 50 years. Aim: To evaluate the effect of cannabis use before partnered sex on women with and without difficulty achieving orgasm. Methods: This observational study evaluated responses from female study participants relating to their demographics, sexual activities, mental well-being, cannabis usage, and orgasm-related questions from the Female Sexual Function Index (FSFI). Outcomes: Outcomes included orgasm frequency, difficulty, and satisfaction related to cannabis use or lack of use before partnered sex, largely based on the FSFI orgasm subscale. Results: Of the 1037 survey responses, 410 were valid and complete. Twenty-three surveys (5.6% returned) were excluded due to failure to meet the study's criteria. Of the valid surveys, most women (52%, n = 202) reported difficulty achieving orgasm during sexual activity with a partner. These women were primarily between 25 and 34 years of age (45%, n = 91); 75% identified their race as White (n = 152/202); 52% (n = 105) identified as LGBTQI+ (lesbian, gay, bisexual, transgender, queer/questioning, intersex, or other); and 82% (n = 165) were married or in a relationship. Among participants who experienced challenges in achieving orgasm, 72.8% (n = 147, P < .001) reported that cannabis use before partnered sex increased orgasm frequency, 67% stated that it improved orgasm satisfaction (n = 136, P < .001), and 71% indicated that cannabis use made orgasm easier (n = 143, P < .001). The frequency of cannabis use before partnered sex correlated with increased orgasm frequency for women who experienced difficulties achieving orgasm (n = 202, P < .001). The reasons for cannabis use before partnered sex resulted in a more positive orgasm response (n = 202, P = .22). Clinical Implications: Cannabis may be a treatment for women with difficulty achieving orgasm during partnered sex. Strengths and Limitations: The researchers examined the challenge of achieving orgasm and considered the covariates reported in the literature, including the FSFI orgasm subscale. The findings may not be generalizable to women who rarely or never use cannabis before sex, women who have never experienced an orgasm, or women who do not have female genitalia. Additionally, the specific type of cannabis used, its chemical composition, the quantity used, and whether or not the partner used cannabis were not assessed in this study. Conclusion: Cannabis-related treatment appears to provide benefit to women who have female orgasm difficulties or dysfunction.

RESUMO

The subjective orgasm experience (SOE) refers to its perception and/or assessment from a psychological viewpoint. Few works have approached this construct from a qualitative perspective and have never taken a consolidated theoretical model as a reference. This study aims to provide qualitative validity evidence to the Multidimensional Model of Subjective Orgasmic Experience, derived from the Orgasm Rating Scale (ORS), to qualitatively address SOE in the contexts of sexual relationships and solitary masturbation, analyzing the terms self-generated by individuals and examining the coincidence with the semantic descriptions of orgasm proposed by the ORS. Four hundred Spanish adults aged 18 to 64 years participated. The Technique of Free Association of Words was applied, and prototypical, frequency, and similitude analyses were performed. A similar description was observed concerning the terms generated in both contexts, with a higher frequency and intensity in the context of sexual relationships. In the context of solitary masturbation, negative orgasmic descriptions were evoked. Participants were able to elicit the vast majority of ORS adjectives, with Affective being the most notable dimension, followed closely by Rewards, especially in masturbation. Most of the adjectives were evoked simultaneously with those of the Affective, with "pleasurable" standing out as the most predominant one. This work provides qualitative evidence to the SOE study, ratifying the semantic composition of the ORS and thus endorsing the Multidimensional Model of Subjective Orgasmic Experience as a good theoretical model from which to continue studying the subjective orgasmic experience.

RESUMO

As a primitive driving force for biological reproduction, sexual behavior (and its associated mechanisms) is extremely complex, and orgasm plays an essential role. The limbic system plays a very important role in regulating human sexual behavior. However, it is not clear which components of the limbic system are related to orgasm sensation. We studied a rare case of spontaneous orgasmic aura in a male patient with temporal lobe epilepsy. Stereoelectroencephalography (SEEG) revealed that the right amygdala was the origin of orgasmic aura. Surgical removal of the medial temporal lobe, including the right amygdala, completely eliminated the patient's seizures. This study demonstrates the critical role of the amygdala in human male orgasm.

RESUMO

A deficit or problematic achievement of female orgasm is often classified as a sexual disorder that creates complications in the sex life of couples. This assumption is generally accepted, even though vaginal anorgasmia is an accepted statistical norm and non-coital methods of generating female orgasm are not as easy as they are for men. Female orgasms manifest themselves in different ways; they are variable and can be dependent on a number of variable factors. Some theories suggest a high degree of correlation between the capacity for orgasmic experience, sexual attitudes and behaviour, but also with reproductive potential or the stability of the given couple's relationship. Female orgasm is often seen as a discriminatory mechanism influencing attitudes towards sexuality or even as a kind of fertility catalyst. There is no consensus on the importance of female orgasm. The results of some relevant studies refute theories about the female orgasm's positive influence on adaptive functions of the couple's relationship, as well as its influence on fertility. The orgasm in women is most likely an evolutionary by-product of its male variant, since the clitoris and penis have an identical embryonic basis of development. Female anorgasmia should not be considered an unquestioned diagnosis, let alone a psychiatric construct leading to a paradigm in which anorgasmia is categorically the cause of frustration or other problems.

RESUMO

INTRODUCTION: The pelvic floor muscles (PFMs) have been suggested to play a key role in sexual function and response in women. However, syntheses of the evidence thus far have been limited to interventional studies in women with pelvic pain or pelvic floor disorders, and these studies have failed to fully capture the involvement of the PFMs in a broader population. AIM: We sought to appraise the evidence regarding the role of the PFMs in sexual function/response in women without pelvic pain or pelvic floor disorders. More specifically, we examined the following: (1) effects of treatment modalities targeting the PFMs on sexual function/response, (2) associations between PFM function and sexual function/response, and (3) differences in PFM function between women with and those without sexual dysfunction. METHODS: We searched for all available studies in eight electronic databases. We included interventional studies evaluating the effects of PFM modalities on sexual outcomes, as well as observational studies investigating the association between PFM function and sexual outcomes or the differences in PFM function in women with and those without sexual dysfunction. The quality of each study was assessed using the Mixed Methods Appraisal Tool. Estimates were pooled using random-effects meta-analyses whenever possible, or a narrative synthesis of the results was provided. MAIN OUTCOMES: The main outcomes were sexual function (based on a questionnaire)/sexual response (based on physiological test), and PFM function (assessment of the PFM parameters such as strength and tone based on various methods). RESULTS: A total of 33 studies were selected, including 14 interventional and 19 observational studies, most of which (31/33) were deemed of moderate or high quality. Ten out of 14 interventional studies in women with and without sexual dysfunctions showed that PFM modalities had a significant effect on sexual function. Regarding the observational studies, a meta-analysis revealed a significant moderate association between PFM strength and sexual function (r = 0.41; 95% CI, 0.08-066). Of the 7 observational studies performed to assess sexual response, all showed that the PFMs were involved in arousal or orgasm. Conflicting results were found in the 3 studies that evaluated differences in PFM function in women with and those without sexual dysfunction. CLINICAL IMPLICATIONS: Our results highlight the contribution of the PFMs in sexual function/response. STRENGTHS AND LIMITATIONS: One strength of this review is the inclusion of a broad range of study designs and outcomes, allowing a thorough synthesis of evidence. However, interpretations of these data should consider risk of bias in the studies, small sample sizes, and the absence of control/comparison groups. CONCLUSION: The findings of this review support the involvement of the PFMs in sexual function/response in women without pelvic pain or pelvic dysfunction. Well-designed studies should be performed to further investigate PFM modalities as part of the management of sexual dysfunction.

RESUMO

BACKGROUND: Subjective orgasm experience (SOE) refers to the perception, assessment, and/or sensation of orgasm on a psychological level, with the particularity that the study of SOE in nonheterosexual populations is currently very scarce. AIM: The study sought to analyze differences in SOE dimensions, comparing the intensity of each adjective of the Orgasm Rating Scale (ORS) and creating a ranking of the adjectives that better represent it in LGB men and women. METHODS: In a sample of 1475 adults organized into 4 groups according to the type of sexual relationships reported, comparisons were made using multivariate analysis of variance and chi-square tests. OUTCOMES: Differences were obtained in the intensity of all the SOE dimensions, and in 23 of the 25 ORS adjectives. RESULTS: Lesbians and bisexual women reported higher intensity in SOE compared with bisexual and gay men. CLINICAL IMPLICATIONS: Because the ORS has been established as a good tool for detecting orgasmic difficulties in nonheterosexual populations, this study could provide LGBT affirmative psychotherapy with evidence on how these individuals evaluate their orgasms in a relational context. STRENGTHS AND LIMITATIONS: This study extends prior limited knowledge about how LGB people evaluate their orgasmic experiences in the context of sexual relationships. Despite this, the study poses limitations such as nonprobability sampling or the inclusion of exclusively cisgender and young individuals, making it difficult to generalize the results. CONCLUSION: Although significant differences were found between LGB men and women, all groups agree on the adjectives they use to describe the subjective experience of orgasm in the context of sexual relationships; therefore, evidence is provided about how LGB people evaluate their orgasmic experiences in this context.

RESUMO

BACKGROUND: Orgasmic phase disorders in men worsen the burden of erectile dysfunction on sexual satisfaction. OBJECTIVES: To investigate the prevalence of and predictors of unreported orgasmic phase disorder in a cohort of men looking for their first urological assessment for new-onset erectile dysfunction in a real-life setting. MATERIALS AND METHODS: Data from 1107 heterosexual, sexually active men consecutively assessed for new-onset erectile dysfunction were analysed. Throughout a comprehensive medical and sexual history, all patients were asked to self-report any orgasmic phase disorder and to complete the International Index of Erectile Function and the Beck's Inventory for Depression (depressive symptoms scored as Beck's Inventory for Depression ≥11). Men self-reporting orgasmic phase disorder during the interview were excluded from further analyses. The median value of the International Index of Erectile Function-orgasmic function domain was arbitrarily used to categorise men with (International Index of Erectile Function-orgasmic function ≤5) and without unreported orgasmic phase disorder (International Index of Erectile Function-orgasmic function >5). Circulating hormones were measured in every patient. Descriptive statistics and logistic regression models were used to test the association between clinical variables and unreported orgasmic phase disorder. RESULTS: Of 1098 patients with non-self-reporting orgasmic phase disorder, 314 (28.6%) had International Index of Erectile Function-orgasmic function ≤5. Patients with erectile dysfunction + unreported orgasmic phase disorder were older (median [interquartile range]: 58 [44-66] years vs. 51 [40-60] years), had higher body mass index [25.8 (23.7-28.1) kg/m2 vs. 25.2 (23.3-27.4) kg/m2 ], higher prevalence of type 2 diabetes (36 [11.5%] vs. 45 [5.7%]) and lower International Index of Erectile Function-erectile function scores (6 [2-10] vs. 18 [11-24]) than men with erectile dysfunction-only (all p < 0.05). Patients with erectile dysfunction + unreported orgasmic phase disorder depicted higher rates of severe erectile dysfunction (75.5% vs. 25%) and Beck's Inventory for Depression ≥11 (22.6% vs. 17.9%) (all p < 0.05). In the multivariable logistic regression analysis, older age (odds ratio: 1.02) and lower International Index of Erectile Function-erectile function scores (odds ratio: 0.83) were independently associated with unreported orgasmic phase disorder (all p < 0.05). CONCLUSIONS: Almost one in three men seeking first medical help for erectile dysfunction depicted criteria suggestive of unreported orgasmic phase disorder. Men with unreported orgasmic phase disorder were older and had higher rates of severe erectile dysfunction and concomitant depressive symptoms. These real-life findings outline the clinical relevance of a comprehensive investigation of concomitant sexual dysfunction in men only complaining of erectile dysfunction to more effectively tailor patient management.

RESUMO

Estradiol (E2) has been implicated in sexual functioning in both sexes. E2 levels change distinctively over the menstrual cycle, peaking around ovulation. Data on short-term effects of fluctuating E2 levels on sexual desire are however sparse and mostly based on observational studies. To fill this gap, we ran a double-blind, randomized, placebo-controlled study (N = 126) to investigate the effects of a short-term increase in E2 on sexual desire and orgasm frequency in healthy, young men and women. Circulating E2 levels were elevated through estradiol valerate (E2V) administered over two consecutive days to simulate the rise in E2 levels around ovulation. E2V had no effect on orgasm frequency and only minor effects on sexual desire. On average, the administered E2V dampened change in sexual desire compared to untreated participants with comparable baseline sexual desire in such a way that sexual desire was slightly reduced even in those with higher baseline sexual desire. These findings suggest that short-term increases in E2 have little effect on sexual function and are unlikely to explain the increase in sexual desire around ovulation.

RESUMO

RATIONALE: Cabergoline (CAB) is an ergot derivative typically prescribed for the treatment of hyperprolactinemia. It suppresses the release of prolactin through agonist actions on dopamine (DA) D2 receptors; however, it possesses binding affinity for other DA and 5-HT receptors. Side effects that exacerbate valvular heart disease can occur with high doses. OBJECTIVE: The present study examined the acute, subchronic, and chronic dose-response effects of CAB and a derivative dimethylcabergoline (DMC) which acts as an antagonist instead of agonist at 5-HT 2B receptors, on appetitive and consummatory sexual behaviors of male rats. METHODS: CAB (0, 0.03, 0.15, or 0.3 mg/kg/ml) was administered daily to sexually experienced male rats (N = 10/dose) by oral gavage for a total of 68 days. Sexual behavior was tested every 4 days during this period for a total of 16 trials. On the 17th trial, rats were administered their dose of CAB, and 4 h after were overdosed with sodium pentobarbital, perfused intracardially, and their brains processed for Fos immunohistochemistry. DMC (0, 0.03, 0.15, 0.3 mg/kg/ml) was administered daily to sexually experienced male rats (N = 10/dose) by oral gavage for a total of 36 days. Sexual behavior was tested every 4 days for a total of 9 trials. RESULTS: CAB increased anticipatory level changes, intromissions, and ejaculations significantly across all timepoints, with the medium and high doses being most potent. The medium and high doses also increased Fos protein significantly within the medial preoptic area, whereas in the nucleus accumbens shell, the low and medium doses decreased Fos protein but the high dose increased it significantly from control. Similar to CAB, the medium and high doses of DMC increased the number of ejaculations significantly. Rats in all drug dose groups appeared healthy for the duration of the experiments. CONCLUSIONS: Both CAB and DMC facilitate ejaculations, and CAB further facilitates measures of anticipatory sexual motivation and intromissions. These data suggest that both could be used as treatments for sexual arousal disorders and ejaculation/orgasm disorders with little or no untoward side effects at low doses.

RESUMO

Post-orgasmic illness syndrome (POIS) is a rare disorder associated with a debilitating symptoms post-ejaculation associated with significant impairment in quality of life. The mechanism of the disease is unclear, but hypersensitivity to semen and/or seminal fluid has been postulated. We present a case of POIS successfully treated with omalizumab suggesting a possible role for this therapy in POIS treatment and management.

RESUMO

Background: Low-dose-rate brachytherapy (LDR-B) is an established treatment for localized prostate cancer. However, while erectile function is relatively well documented, other changes in sexual function are sparsely investigated. Aim: The study sought to investigate orgasmic dysfunction, urinary incontinence during sexual activity (UIS), changes in penile morphology, and sensory disturbances in the penis following LDR-B. Methods: A cross-sectional questionnaire-based study in patients who underwent LDR-B at our center from 2010 to 2020. The questionnaire included the International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and questions on orgasm, UIS, changes in penile morphology, and penile sensory disturbances. Outcomes: Outcomes were prevalence rates of altered perception of orgasm, orgasm associated pain, anejaculation, UIS, alterations in penile morphology, penile sensory disturbances, and predictors of these side effects. Results: Overall, 178 patients responded to the questionnaire. The median age was 70 years (range, 51-83 years), and the median time since LDR-B was 93 months (range, 21-141 months).Overall, 142 (80%) were sexually active and 126 (70.8%) had erectile dysfunction (ED). Of the sexually active patients, 8 (5.6%) reported anejaculation and 7 (4.9%) reported anorgasmia. Another 67 (46.9%) had decreased orgasmic intensity, while 69 (49.3%) reported an increased time to orgasm. Twenty-six (18.3%) patients had experienced orgasm-associated pain with a median visual analog pain score of 2. Considering overlap, 44 (31.0%) patients had an unchanged orgasmic function. Six (3.3%) patients had experienced UIS at least a few times. Penile length loss was reported by 45 (25.2%) patients. Seventeen (9.6%) patients reported an altered curvature of their penis and 9 (5%) had experience painful erection. Thirty-three (18.5%) patients had experienced decreased penile sensitivity. On multivariate analyses, ED was the only independent risk factor for altered perception of orgasm (odds ratio [OR], 6.6; P < .0001), orgasmic pain (OR, 5.5; P = .008), and penile shortening (OR, 4.2; P < .0056). No independent risk factors were identified for UIS or sensory penile disturbances. Clinical implications: Patients undergoing LDR-B should be adequately informed about possible side effects, and clinicians should inquire about these during follow-up visits. Strength and Limitations: We are the first to comprehensively explore the previously neglected side effects of LDR-B for prostate cancer. Limitations are the cross-sectional design assessing the cohort at different time points following their treatment and the response rate. Conclusions: Orgasmic dysfunction, changes in penile morphology, and sensory disturbances in the penis are common side effects of LDR-B for prostate cancer. UIS is only experienced by a small minority.

RESUMO

Background: Female Reddit users frequently discussed potential causes of orgasm difficulties and its implications on mental health and relationships. Aim: This study aimed to evaluate the experiences of women discussing orgasms on the Internet site Reddit. We sought to qualitatively analyze the topics that arose in users' discussions to better understand the potential causes of orgasm difficulties and its implications on quality of life. Methods: Posts on the subreddit r/TwoXChromosomes containing the keywords "orgasm" and "climax" were included in the dataset. Posts and their associated comments were qualitatively analyzed using the grounded theory approach. Two independent researchers coded each thread to identify dominant themes and emergent concepts. Outcomes: The most frequently coded primary topics included: (1) orgasm (32.2% [n = 337]), (2) psychological (17.8% [n = 186]), (3) relationships (15.4% [n = 161]), and (4) treatment (10.7% [n = 112]). Results: Qualitative analysis of 107 threads and approximately 6300 comments resulted in 5 major categories: psychological aspect of orgasms, difficulty orgasming with partners, partners' responses to orgasmic dysfunction, types of orgasms, and treatments for orgasmic dysfunction. Preliminary themes included (1) the presence of an emotional component or history of trauma related to orgasmic difficulty, (2) difficulty orgasming with a partner regardless of ability to orgasm during masturbation and a variety of stimulation required to orgasm, (3) mixed partner responses to orgasmic dysfunction, (4) the definition of a normal orgasm, and (5) self-motivated treatment for orgasmic dysfunction, including clitoral stimulation devices and masturbation techniques. Notably, few posters discussed their orgasmic dysfunction with healthcare providers. Clinical Translation: The study reveals insights into the possible causes, psychosocial implications, and treatment of orgasm difficulties from a patient perspective, and can guide future research on female orgasms in a more precise, patient-oriented direction. Strengths and Limitations: The anonymous nature of the forum allowed for insight into sensitive topics related to female orgasms and sexual trauma. Limitations include the demographic distribution of Reddit users, which was primarily younger women in their 20s and 30s, which restricts generalizability. Conclusion: Reddit provides a medium for individuals with orgasm difficulties to discuss their experiences. Posts addressed users' inability to orgasm, their mental health and relationships, the stimulation required for orgasm, and treatments for orgasmic dysfunction. Interestingly, very few posts discussed healthcare, potentially suggesting that women do not classify their orgasmic dysfunction as a health issue.

RESUMO

BACKGROUND: Postorgasmic illness syndrome (POIS) is a rare syndrome in which patients experience various physical and cognitive symptoms after ejaculation, and its pathophysiology remains unknown. AIM: The aim of this study was to characterize the clinical presentations, disease course, and treatment outcomes in outpatients, as well as to examine the validity of the preliminary criteria and symptom clusters of POIS. METHODS: This retrospective monocentric study was conducted in a neurourology department, with patients included from 2010 to 2023. The diagnostic criteria and symptom cluster descriptions were based on previous studies. OUTCOMES: The study focused on the clinical features of POIS, the complementary tests performed, the treatments tried, and their effectiveness. RESULTS: Thirty-seven men were included in the study, with symptom onset occurring at a mean ± SD age of 23.6 ± 7.4 years. The mean time from ejaculation to symptom onset was 1 hour 22 minutes ± 3 hours 42 minutes. The mean duration of symptoms was 4.7 ± 3.4 days. Seventeen patients (46%) developed the symptoms primarily, whereas in 20 (54%) they appeared secondarily. All preliminary criteria were met in 19 patients (51%). The most common symptom clusters were "general" in all 37 patients (100%; eg, asthenia and concentration difficulties) and "head" in 35 patients (95%; mostly headache and a foggy feeling). In terms of treatments, antihistamines and nonsteroidal anti-inflammatory drugs were tried and partially improved symptoms for some patients. CLINICAL IMPLICATIONS: This study helps to further characterize POIS by specifying the most frequent symptoms and comparing them with the initial criteria. STRENGTHS AND LIMITATIONS: To our knowledge, this is one of the largest cohorts of patients consulting for symptoms suggestive of POIS. There are limitations due to the retrospective nature of the data collection, such as missing data and imprecision of treatment efficacy. CONCLUSION: The majority of participants met at least 3 of the preliminary diagnostic criteria, with a majority of symptoms in the general and head clusters. However, the determination of predictive factors for treatment response based on the typology of the disorders remains to be established.

RESUMO

Selective serotonin reuptake inhibitors (SSRIs) are the cornerstone of psychopharmacology. However, they cause side effects such as sexual dysfunction, leading to the discontinuation of treatment. We aimed to investigate the efficacy and safety of drug holidays for women experiencing sexual dysfunction Induced by SSRIs other than fluoxetine. This study was an 8-week randomized, open-label, controlled trial including married women aged between 18 and 50 years who had experienced sexual dysfunction while undergoing treatment with SSRIs. The intervention group implemented drug holidays by not taking medications on Thursdays and Fridays, while the control group continued regular medication use. The female sexual function index (FSFI) and the 28-question general health questionnaire (GHQ-28) were administered to assess sexual function and mental health, respectively. A total of 50 participants completed the trial. The drug holidays' group showed significant improvements in arousal (p < 0.001), desire (p = 0.001), orgasm (p < 0.001), satisfaction (p < 0.001), lubrication (p = 0.021), and overall sexual health (p < 0.001). The between-group difference of pain was significant (p < 0.001), despite no significant within-group change. Mental health improved in both groups, despite no significant between-group difference. No major adverse effects were reported. Drug holidays did not introduce immediate safety concerns or significant adverse effects during the timeframe of eight weeks, suggesting that it may be a safe and effective strategy for managing SSRI-induced sexual dysfunction in women, alongside improving mental health. Further research is needed to reach a definitive conclusion.
