Abusive use of anabolic androgenic steroids, male sexual dysfunction and infertility: an updated review.

The evolving prevalence of anabolic androgenic steroids (AAS) abuse among nonathletes is alarming because of the known harm to an individual's health. Among the adverse effects of AAS abuse, male infertility and sexual dysfunction have been often reported in the literature, but little is known regarding its actual prevalence, possible underpinning mechanisms, and potential treatments either during or post-AAS usage. Thus, the current narrative review summarizes the state-of-art regarding the effects of AAS on male fertility and sexual function. Evidence was gathered from the latest reviews and recent original studies, specifically from prospective cohorts and clinical trials, ultimately resulting in five main topics of discussion. First, AAS usage is briefly characterized by its historical background, main physiological mechanisms, and the most frequently used AAS substances. Second, data on the prevalence of AAS-induced male infertility and sexual dysfunction are described. Third, some new insights on possible underpinning mechanisms of AAS-induced male infertility and sexual dysfunction are thoroughly discussed, with particular attention to histological data derived from animal models and the latest insights from prospective cohorts in humans. Fourth, the potential treatments during and after the AAS usage are presented, highlighting the odds of resolving male infertility and sexual dysfunction. Fifth, future directions on this topic are discussed, focusing on the methodological robustness of scientific studies.

Phytocompounds from Amazonian Plant Species against Acute Kidney Injury: Potential Nephroprotective Effects.

There are several Amazonian plant species with potential pharmacological validation for the treatment of acute kidney injury, a condition in which the kidneys are unable to adequately filter the blood, resulting in the accumulation of toxins and waste in the body. Scientific production on plant compounds capable of preventing or attenuating acute kidney injury-caused by several factors, including ischemia, toxins, and inflammation-has shown promising results in animal models of acute kidney injury and some preliminary studies in humans. Despite the popular use of Amazonian plant species for kidney disorders, further pharmacological studies are needed to identify active compounds and subsequently conduct more complex preclinical trials. This article is a brief review of phytocompounds with potential nephroprotective effects against acute kidney injury (AKI). The classes of Amazonian plant compounds with significant biological activity most evident in the consulted literature were alkaloids, flavonoids, tannins, steroids, and terpenoids. An expressive phytochemical and pharmacological relevance of the studied species was identified, although with insufficiently explored potential, mainly in the face of AKI, a clinical condition with high morbidity and mortality.

Clinical Safety of a Pharmaceutical Formulation Containing an Extract of Acmella oleracea (L.) in Patients With Premature Ejaculation: A Pilot Study.

Acmella oleracea (L.) R. K. Jansen (Asteraceae) is a plant species widely used in traditional Amazonian medicine to treat sexual dysfunction. The use of this plant has gained popularity because of its sensory properties, such as a tingling sensation. In this study on patients with premature ejaculation, we evaluated the clinical action of a nano-formulation containing an ethanolic extract of A. oleracea inflorescences. Major constituents in the extracts were identified based on gas chromatographic analysis. Participants used a spray preparation based on the A. oleracea extract for 12 weeks, during which they were instructed to apply the product 5 min prior to sexual intercourse. To assess therapeutic efficacy, participants were required to record the mean intravaginal latency time for ejaculation (IELT). During the period of spray treatment, the nano-formulation of A. oleracea increased participant IELT values (M = 293 s) compared with the baseline values (193 s). This nano-formulation reported clinical action in patients with premature ejaculation. It is accordingly considered to have potential application as a therapeutic alternative with benefits for both patients and their partners. Given the small number of participants in this study, further multicenter studies involving a larger number of participants are needed to confirm these observations.

SARS-CoV-2 Nucleocapsid Protein is Associated With Lower Testosterone Levels: An Experimental Study.

The ongoing COVID-19 pandemic represents an extra burden in the majority of public and private health systems worldwide beyond the most pessimistic expectations, driving an urgent rush to develop effective vaccines and effective medical treatments against the SARS-CoV-2 pandemic. The Nucleocapsid structural viral protein is remarkably immunogenic and hugely expressed during infection. High IgG antibodies against Nucleocapsid protein (N protein) levels were detected in the serum of COVID-19 patients, confirming its pivotal antigen role for a T lymphocyte response in a vaccine microenvironment. Currently, adverse events associated with immunizations have raised some degree of concern, irrespective of its huge benefits in dealing with disease severity and decreasing mortality and morbidity. This hitherto study evaluates histological changes in rats' testes, epididymis, prostate, and seminal vesicles and analyzes hormone levels after solely N protein inoculation. Therefore, we exposed a group of Lewis rats to weekly injections of the recombinant N protein for 28 days, while a control group was inoculated with a buffer solution. The N group revealed a more significant number of spermatozoa. Spermatozoa in the seminiferous tubules were counted in twenty 400 × microscopy fields (mean of 9.2 vs. 4.6 in the control group; p < 0,01), but significantly lower testosterone levels (mean of 125.70 ng/dl vs. 309,00 ng/dl in the control group; p < 0,05) were found. No other histological and biochemical changes were displayed. Conclusively, these data suggest testicular hormonal imbalance mediated by the SARS-CoV-2 N protein that could be linked to reported post-COVID-19 syndrome hypogonadism. More relevant research might be performed to confirm this viral antigen's deleterious mechanism in the human testicular microenvironment, particular in Leydig cell function.

Impact of COVID-19 Pandemic on the Sexual Function of Health Professionals From an Epicenter in Brazil.

INTRODUCTION: The pandemic caused by the COVID-19 resulted in worldwide social isolation and leading to significant personal distress, particularly among health professionals on the front lines. Those factors' relevance and their impact on sexual function in this population have not yet been established. AIM: To evaluate the impact of the pandemic on sexual function in healthcare professionals and medical students at a reference center in the treatment of COVID-19 in Brazil. METHODS: A cross-sectional analysis with online questionnaires about sexual function was sent to health professionals and medical students from the HC-FMUSP medical complex. The questionnaire evaluated Total Sexual and Masturbatory Frequency prior and during the pandemic, libido and sexual satisfaction changes with a detailed inquire about demographics and personal factors. An objective assessment of sexual function was also made using the validated sexual quotient questionnaires. MAIN OUTCOME MEASURES: Differences in intercourse frequency, libido, and overall sexual satisfaction, in a sample of healthcare professionals particularly vulnerable to the pandemic effects. RESULTS: A total of 1,314 responses were available with a mean age of 37 years. Worsening of sexual satisfaction was reported by 44.5% of the participants, with the following associated factors: Lower libido, missing Nightlife, Higher Masturbatory Frequency, and isolation from the partner. Remaning sexualy actively and having higher sexual frequency appear to decrease the chance of worsening sexual function. Worsening of Libido was reported by 37% and had several associated factors, including missing of Nightlife, older age, isolation from the partner among others. Being male and sexually active was associated with a smaller chance of reporting lower libido. CONCLUSION: We were able to observe a sharp drop in Libido and General Sexual Satisfaction. Although an increase in pornography consumption and masturbatory frequency did occur, these factors were not associated with greater sexual satisfaction. The impact of COVID-19 on this population's sexual health is not to be underestimated and should be further studied in the follow-up of the pandemic.

Cut-off values of the Johnsen score and Copenhagen index as histopathological prognostic factors for postoperative semen quality in selected infertile patients undergoing microsurgical correction of bilateral subclinical varicocele.

BACKGROUND: It remains challenging to determine which individuals are likely to benefit from microsurgical correction of subclinical varicocele, as basic semen parameters often do not improve postoperatively. We aimed to develop an easily accessible tool for prognostic stratification of infertile men indicated for microsurgical correction of bilateral subclinical varicocele characterized by prolonged and clear venous reflux and no other cause for infertility. METHODS: We retrospectively analyzed the testicular biopsy, seminal analysis, and ultrasound evaluation records of 20 men managed between 2006 and 2014. Subclinical varicocele was diagnosed through bilateral testicular palpation and auscultation of venous reflux using a Doppler stethoscope, with confirmation on color Doppler sonography. We conducted receiver operating characteristic curve analysis to identify the optimal combinations of cut-offs for the Johnsen score, Copenhagen index, and testicular volume defining histological patterns with positive prognostic value for improved postoperatively reproductive capacity. RESULTS: Positive prognostic value was noted for the following combinations of parameters: (I) Johnsen score >8.2 in the left testicle and right testicular volume >12.8 mL predicted improved sperm concentration; (II) Johnsen score >8.2 and Copenhagen index digit II <2.5 bilaterally predicted improved total sperm motility; (III) Johnsen score >9.1 and Copenhagen index digit III <1.5 bilaterally predicted improved progressive sperm motility; (IV) Johnsen score >7.9 and right testicular volume >13.6 mL predicted improved sperm morphology. CONCLUSIONS: Johnsen score and Copenhagen index as histopathological prognostic factors can be easily obtained upon evaluation of testicular biopsy specimens and can be simple and reliable tool to establish a more realistic prognosis for reproductive capacity in men who undergo microsurgical correction of subclinical varicocele with no other detectable cause for infertility.
