Off-label use of clomiphene citrate to treat anabolic androgenic steroid induced hypogonadism upon cessation among men (CloTASH) - A pilot study protocol.

Background: Non-prescribed anabolic androgenic steroid (AAS) use is associated with AAS-induced hypogonadism (ASIH), and metabolic, cardiovascular, and mental health risks. Symptoms of ASIH (fatigue, depression, anxiety, sexual dysfunction) are hard to endure following cessation, but there is no consensus on whether endocrine treatment should be used to treat ASIH. This proof-of-concept study aims to explore safety of off-label clomiphene citrate therapy, whether the treatment will reduce the symptoms of androgen deficiency, and to study changes in health risks after cessation. Methods: In this open-labeled non-randomized off-label hormone intervention pilot study, we shall include males with AAS dependence intending to cease use. The 16-week intervention included clomiphene citrate, transdermal testosterone gel for the first four weeks and optional human chorionic gonadotropin (hCG) from week 4 if low treatment response. Measures of physical and mental health will be examined from ongoing AAS use, during the intervention, and at 6- and 12 months post cessation. Change in self-reported symptoms of hypogonadism and other withdrawal symptoms will be compared with data from a group of men who ended AAS use temporarily without the medical intervention. The study may provide valuable clinical insights and may be used to inform the design of future intervention studies.

Drainage by Ovarian Incision for the Treatment of Massive Ovarian Edema Torsion During Pregnancy.

Massive ovarian edema (MOE) is a rare benign condition presenting as unilateral ovarian enlargement with stromal edema, and only a limited number of MOE cases during pregnancy have been reported. MOE is often complicated by ovarian torsion, which requires detorsion. Although the diagnosis of MOE can be made using ultrasound and magnetic resonance imaging, its rarity makes diagnosis difficult, usually leading to overtreatment. Preserving the ovary in the treatment of MOE torsion is essential, and consideration of oophoropexy after detorsion is often reported. However, fixing an enlarged ovary to the pelvic wall in the limited space of the pelvis is challenging. Herein, we present a case of MOE of the right ovary diagnosed at the fifth week of gestation after ovulation induced by clomiphene citrate. Torsion of the ovary occurred in the seventh week. We achieved preservation of the ovary through laparoscopic surgery with detorsion and drainage by making a small incision to the enlarged ovary, resulting in an immediate size reduction. There was no recurrence of torsion or MOE throughout the pregnancy, and the patient gave birth in the 39th week of gestation. This is the third reported case of MOE after ovulation using clomiphene citrate, and it highlights the effectiveness of treatment with detorsion and a small incision of the ovary via laparoscopic surgery in patients with MOE torsion during pregnancy.

Infertility Challenge in a Cryptozoospermic Patient With Y Chromosome Microdeletion.

A couple is usually diagnosed with infertility if they have regular, unprotected sexual activity for a year or longer and are unable to conceive. Male infertility can be categorised into three types: obstructive infertility, non-obstructive infertility, and coital infertility. A major contributing factor for infertility in men is Y chromosome microdeletion, which is a non-obstructive infertility that involves problems related to sperm production. Deletions in the azoospermia factor region known as azoospermia factor a (AZFa), azoospermia factor b (AZFb), and azoospermia factor c (AZFc) loci independently or together which are situated on the Y chromosome cause a disturbance and alteration that are linked to either a reduction in sperm count, known as oligozoospermia, or the absence of sperm cells in the semen sample, referred to as azoospermia. Observations indicate that individuals with AZFc microdeletion may display irregularities in endocrine hormones. Men experiencing hormonal abnormalities affecting sperm production may receive treatment with clomiphene citrate. In cases of azoospermia and numerous cryptozoospermic patients, intracytoplasmic sperm injection is frequently considered the primary therapeutic approach.

Long-term use of clomiphene in male macroprolactinomas with persistent hypogonadism.

BACKGROUND: Men with macroprolactinoma can present persistent hypogonadism despite normoprolactinemia achieved with clinical and/or neurosurgical treatment. Usually, testosterone replacement therapy is indicated. Nevertheless, although off-label, clomiphene citrate (CC), a selective estrogen receptor modulator, has also been used, mainly when fertility is an issue. The aim of this study is to evaluate the effectiveness of CC in recovering the gonadal axis in men with macroprolactinoma, with or without hyperprolactinemia, and evaluate its safety as a long-term therapy. METHODS: This is a retrospective study including 10 men with macroprolactinoma on cabergoline treatment and persistent hypogonadism. All patients received initially 50 mg/d of CC. RESULTS: The median age at diagnosis of prolactinomas was 34 (range, 26-60) years old. All patients were treated with cabergoline at a median maximum dose of 2 (1-7) mg/week, with a median time of treatment of 8.5 (2-15) years. Prolactin was still above the normal range when CC was introduced only in two patients. The mean duration of CC therapy was 3.2 (±2.8) years. Prolactin levels maintained stable (p = 0.252) and testosterone increased (p = 0.027) significantly on CC therapy. Tumor size remained stable. Eight patients (80%) maintained testosterone above 300 ng/dL and were classified as responders. Three responders succeeded in using a lower dose of CC and one of them completed withdrawal CC and maintained eugonadism. There were no side effects or safety concerns reported. CONCLUSION: CC should be seen as a safe treatment option for men with macroprolactinoma and persistent hypogonadism.

Clomiphene Citrate Administered in Periconception Phase Causes Fetal Loss and Developmental Impairment in Mice.

Clomiphene citrate is a common treatment for ovulation induction in subfertile women, but its use is associated with elevated risk of adverse perinatal outcomes and birth defects. To investigate the biological plausibility of a causal relationship, this study investigated the consequences in mice for fetal development and pregnancy outcome of periconception clomiphene citrate administration at doses approximating human exposures. A dose-dependent adverse effect of clomiphene citrate given twice in the 36 hours after mating was seen, with a moderate dose of 0.75 mg/kg sufficient to cause altered reproductive outcomes in 3 independent cohorts. Viable pregnancy was reduced by 30%, late gestation fetal weight was reduced by 16%, and ∼30% of fetuses exhibited delayed development and/or congenital abnormalities not seen in control dams, including defects of the lung, kidney, liver, eye, skin, limbs, and umbilicus. Clomiphene citrate also caused a 30-hour average delay in time of birth, and elevated rate of pup death in the early postnatal phase. In surviving offspring, growth trajectory tracking and body morphometry analysis at 20 weeks of age showed postweaning growth and development similar to controls. A dysregulated inflammatory response in the endometrium was observed and may contribute to the underlying pathophysiological mechanism. These results demonstrate that in utero exposure to clomiphene citrate during early pregnancy can compromise implantation and impact fetal growth and development, causing adverse perinatal outcomes. The findings raise the prospect of similar iatrogenic effects in women where clomiphene citrate may be present in the periconception phase unless its use is well-supervised.

Clomiphene citrate as a new modality in management of vaginal bleeding with depomedroxyprogesterone acetate (DMPA): A randomized controlled trial.

BACKGROUND: Depo-medroxyprogesterone acetate (DMPA) functions as a contraceptive method by inhibiting the secretion of gonadotropins, which prevents follicular maturation and ovulation, as well as thinning of the endometrium leading to unscheduled vaginal bleeding and subsequent discontinuation of DMPA. Our study aimed to evaluate the efficacy and safety of clomiphene citrate (CC) in stopping bleeding among DMPA users. MATERIALS AND METHODS: We randomly assigned 200 DMPA users using a computer-generated random numbers table in a 1:1 ratio to one of two groups; the study group, which received CC at a dose of 50 mg twice daily for five days (n = 100), and the control group, which received a placebo for five days (n = 100). Our primary outcome measure was the onset and duration of bleeding cessation. Secondary outcomes included endometrial thickness, recurrence of vaginal bleeding, and any reported side effects associated with CC use. RESULTS: Clomiphene citrate significantly resulted in early cessation of vaginal bleeding in 83 % of the patients, which continued for three months of follow-up. In addition, the recurrence of vaginal bleeding was significantly reduced in the CC group compared to the control group (11 % vs. 67 %; p < 0.001). Endometrial thickness was significantly greater in the CC group than in the control group (p < 0.001). Breast tenderness was more frequently reported in the study group, with no difference in dyspareunia between the two groups. CONCLUSIONS: Clomiphene citrate is effective in controlling bleeding among DMPA users. Further studies are encouraged to confirm our findings.

Recuperación de la espermatogénesis tras el abuso de esteroides anabólicos androgénicos en varones. Revisión sistemática de la literatura / Recovery of spermatogenesis after androgenic anabolic steroids abuse in men. A systematic review of the literature

Objetivo El objetivo de esta revisión sistemática es identificar el tratamiento óptimo para la infertilidad masculina derivada del abuso de esteroides anabólicos androgénicos (EAA). Métodos Se llevó a cabo una revisión sistemática según la declaración Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Se incluyeron estudios que comparaban distintos protocolos para la recuperación de la espermatogénesis tras el uso de EAA. Resultados Un total de 13 estudios que investigaban diferentes protocolos para recuperar la espermatogénesis en pacientes con abuso de EAA cumplieron los criterios de inclusión. Entre los agentes disponibles que demostraron eficacia en el reestablecimiento de la espermatogénesis se encuentran las gonadotropinas inyectables, los moduladores selectivos de los receptores de estrógenos (SERM) y los inhibidores de la aromatasa (AI), pero su uso apenas ha sido descrito en la literatura. Conclusiones Los médicos deben conocer los efectos adversos que los EAA pueden tener sobre la espermatogénesis. La infertilidad asociada a estos agentes puede ser de carácter reversible, pero la producción de espermatozoides puede tardar más de un año en normalizarse. Tanto el tratamiento conservador como el agresivo pueden estimular la espermatogénesis con resultados satisfactorios. Se requiere una mayor comprensión de la endocrinología reproductiva masculina y datos de alta calidad sobre la recuperación de la espermatogénesis tras el abuso de EAA. (AU)

Objective This systematic review aims to evaluate the optimal treatment for male infertility resulting from Anabolic Androgenic Steroids (AAS) abuse. Methods A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies that compared different protocols for the recovery of spermatogenesis in patients after AAS use were included. Results 13 studies investigating different protocols to restore spermatogenesis in patients with AAS abuse met the inclusion criteria. The available agents that showed restoration of spermatogenesis include injectable gonadotropins, selective estrogen receptor modulators, and aromatase inhibitors, but their use is still poorly described in the literature. Conclusions Clinicians need to be aware of the detrimental effects of AAS on spermatogenesis. AAS-associated infertility may be reversible, but sperm production may take over a year to normalize. Both conservative and aggressive treatment can boost spermatogenesis with positive results. Further understanding of male reproductive endocrinology and high-quality data on the field of restoration of spermatogenesis after AAS abuse are warranted. (AU)

Efficacy of Letrozole vs Clomiphene Citrate for induction of ovulation in women with polycystic ovarian syndrome.

Objective: To compare the efficacy of letrozole vs Clomiphene citrate for ovulation induction in PCOS women. Methods: This double blind randomized controlled trial was conducted at Services Hospital, Lahore, from January 2016 to December 2020. Total 220 patients, diagnosed with PCOS according to Rotterdam criteria were randomly assigned into two groups after taking informed consent. The women were followed for ovulation, pregnancy and live birth rates in the next five consecutive menstrual cycles with either clomiphene citrate or letrozole. Results: Letrozole had significantly better pregnancy rate (29.0% vs 15.4% p-value 0.015), monofollicular development (77.2% vs 52.7% p-value 0.000) and live birth rate (25.4% vs 10.9% p-value 0.005) as compared to clomiphene citrate. There was no difference between the two groups in ovulation rate (68.1% vs 63.6%, p-value 0.477), early pregnancy loss (3.6% vs 4.5% p-value 0.734), and twin pregnancy (0.0% vs 1.81% p-value 0.155). There was no ectopic pregnancy and no congenital anomalies in both groups. Hot flushes were higher in clomiphene group (31.8% vs 12.7% p-value 0.001) while fatigue (30.9% vs 8.1% p-value 0.000) and dizziness (21.8% vs 10.0% p-value 0.029) was higher with letrozole but these were well tolerated. Conclusion: Letrozole is better treatment choice than clomiphene citrate in PCOS women with infertility in terms of pregnancy and live birth rate.ClinicalTrials.gov Identifier: NCT05702957.

Clinical and neonatal outcomes of complete zona pellucida removal by laser-assisted hatching after single vitrified-warmed blastocyst transfer.

Laser-assisted hatching (LAH) is a widely used and unavoidable technique in assisted reproductive technology after frozen embryo transfer (FET). We aimed to investigate the safety and efficacy of completely ZP (zona pellucida) removed by an assisted laser group compared to an intact group after FET. This retrospective study involved 320 SVBT  single vitrified-warmed blastocyst transfers of 213 patients who underwent clomiphene citrate (CC) based minimal stimulation protocol. This study compared 160 SVBT with ZP that were completely removed using laser-assisted (laser beams of 10-15, a wavelength of 1.48 µm, and duration of 1.8-2.2 ms) to 160 cases of intact SVBT. Fisher's exact test, chi-squared test, and logistic regression are used for statistical analysis. The women's age, cause of infertility, BMI, transferred embryo day, insemination methods, and blastocyst grade were not significantly different between two groups. The implantation rate (66.2% vs. 51.2%, P < 0.01), the clinical pregnancy rate (CPR, 52.5% vs. 39.3%, P = 0.01), and the live birth rate (LBR, 43.7% vs. 29.3%, P < 0.01) were significantly higher in the completely ZP removed than the intact group. In logistic regression analysis, the laser-assisted hatching group showed about 2 times higher implantation rate and CPR and LBR than the control group. But miscarriage, gestational weeks, gender, birth weight, and twin births were insignificant between two groups. Our study suggests ZP free embryo transfer by assisted laser is more effective and safer than intact embryo transfer.

Comparison of Letrozole and Clomiphene Citrate in Pregnancy Outcomes in Patients with Polycystic Ovary Syndrome: A Systematic Review and Meta-analysis.

Clomiphene citrate (CC) and letrozole are the predominant medical interventions for the management of infertility in patients with polycystic ovary syndrome (PCOS). To comprehensively summarize the evidence, a systematic review and meta-analysis of randomized clinical trials (RCTs) was carried out to assess the effect of letrozole and CC on pregnancy outcomes in PCOS patients. We searched PubMed/MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials from inception to January 2023. We included RCTs conducted on PCOS women comparing letrozole to CC and assessing endometrial thickness, the number and size of follicles, and ovulation and pregnancy rates. The endpoints were summarized as risk ratio (RR) or standardized mean difference (SMD) with 95% confidence interval (CI) using the random-effects model. Heterogeneity was examined using the I2 statistic. Fifty trials met our inclusion criteria. The mean endometrial thickness was significantly higher in the letrozole group compared to CC group (SMD: 0.89; 95% CI: 0.49, 1.28; I2=97.72%); however, the number of follicles was higher in the CC group (SMD: -0.56; 95% CI: -0.96, -0.17; I2=96.34%). Furthermore, letrozole intake induced higher ovulation rate (RR: 1.20; 95% CI: 1.13, 1.26; I2=54.49%) and pregnancy rate (RR: 1.44; 95% CI: 1.28, 1.62; I2=65.58%) compared to CC. Compared to CC, letrozole has a positive effect on endometrial thickness, monofollicular development, and ovulation and pregnancy rates suggesting that letrozole may be a strong alternative to CC as a first-line medical intervention for chronic anovulation in PCOS women. Larger studies are warranted to further clarify these findings.

Prevention of moderate and severe ovarian hyperstimulation syndrome: a guideline.

This systematic review aims to identify who is at high risk for developing ovarian hyperstimulation syndrome, along with evidence-based strategies to prevent it and replaces the document of the same name last published in 2016.

Clomiphene citrate plus letrozole versus clomiphene citrate alone for ovulation induction in infertile women with ovulatory dysfunction: a randomized controlled trial.

BACKGROUND: The aim of this study was to compare the efficacy of the combination of clomiphene citrate (CC) and letrozole to that of CC alone in inducing ovulation in infertile women with ovulatory dysfunction. METHODS: A randomized controlled trial was conducted at a single academic medical center between November 2020 and December 2021. Anovulatory infertility females, aged 18 to 40, were evenly distributed by a computer-generated block of four into two treatment groups. A "combination group" received a daily dose of CC (50 mg) and letrozole (2.5 mg), while a "CC-alone group" received a daily dose of CC alone (50 mg). The study medications were administered on days 3 through 7 of menstrual cycle. The primary outcome was the ovulation rate, defined by serum progesterone levels exceeding 3 ng/mL at the mid-luteal phase. The secondary outcomes were ovulation induction cycle characteristics, endometrial thickness, conception rate, and adverse events. RESULTS: One hundred women (50 per group) were enrolled in the study. The mean age was not significantly different in both groups: 31.8 years in the combination group and 32.4 years in the CC-alone groups (P = 0.54). The prevalence of polycystic ovary syndrome in the combination and CC-alone groups was 48% and 44%, respectively (P = 0.841). According to intention-to-treat analysis, the ovulation rates were 78% and 70% in the combination and CC-alone groups, respectively (P > 0.05). There was no significant difference in the mean endometrial thickness or the number of dominant follicles of the groups. No serious adverse events were observed in either group. CONCLUSIONS: Our study found no significant difference between the combination of CC and letrozole and CC alone in inducing ovulation in infertile women with ovulatory dysfunction in one cycle. The small number of live births precluded any meaningful statistical analysis. Further studies are needed to validate and extend our findings beyond the scope of the current study. TRIAL REGISTRATION: The study was registered at https://www.thaiclinicaltrials.org with the following number: TCTR20201108004 and was approved on 08/11/2020.

Clomiphene Citrate in the Management of Infertility in Oligospermic Obese Men with Hypogonadism: Retrospective Pilot Study.

Background and Objectives: Obesity is a significant risk factor for hypogonadism and infertility that is further associated with reduced semen quality. The aim of this study is to evaluate the effect of clomiphene citrate (CC), prescribed for treating infertility, on serum testosterone and semen parameters, particularly in oligospermic obese hypogonadal men. Materials and Methods: A retrospective analysis of data related to men (n = 53) who underwent CC treatment for infertility and hypogonadism (testosterone < 300 ng/dL) was performed. Patients with obesity (BMI ≥ 30 kg/m2) and sperm concentration ≤ 15 × 106/mL were included for analysis. Results: The overall results showed that, in oligospermic obese men (n = 31), treatment with CC significantly improved baseline sperm concentration (4.5 ± 6.8 × 106/mL vs. 11.4 ± 15.5 × 106/mL, p < 0.05) and motility (31.5% ± 21.5% vs. 42.6% ± 14.7%, p < 0.05). Furthermore, subsequent examination of oligospermic hypogonadal obese men treated with CC (n = 13) revealed substantial improvements in baseline serum testosterone levels (193.8 ± 59.3 ng/dL vs. 332.7 ± 114.8 ng/dL, p < 0.05) along with an increase in sperm concentration, total motility, and normal morphology. Conclusions: The results of this retrospective study suggest that CC treatment not only improves chances of fertility outcomes by substantially improving semen parameters but also increases total serum testosterone levels in oligospermic obese men without any supplemental and expensive testosterone replacement therapy.

Strong social disparities in access to IVF/ICSI despite free cost of treatment: a French population-based nationwide cohort study.

BACKGROUND: Access to IVF/ICSI is facilitated when the financial barrier is removed. In a national context where in vitro fertilisation (IVF)/intracytoplasmic sperm Injection (ICSI) treatment is cost-free, how many women do not access IVF/ICSI and what are the factors associated with non-access? METHODS: Using French national health insurance databases, the cohort included 20,240 women aged 18-43 years living in France who underwent unsuccessful treatment (no pregnancy) with clomiphene citrate (CC) and/or gonadotropins with treatment started between January and August 2016. The outcome measure was non-access to IVF/ICSI during the 24-month following start of infertility care. Factors associated with non-access to IVF/ICSI were explored using mixed effects logistic regression. RESULTS: In the cohort, 65.4% of women did not access IVF/ICSI. In multivariable analysis, non-access to IVF/ICSI was higher in younger women (18-25 years: (OR 2.17, 95% CI: 1.85-2.54) and in older women (40-43 years: (OR=3.60, 95% CI: 3.25-3.98)). Non-access was higher among women below the poverty line (OR=3.76, 95% CI: 3.34-4.23) and showed a significant upward trend with increasing deprivation of place of residence. Distance to the nearest fertility centre was not significantly associated with non-access to IVF/ICSI. CONCLUSIONS: In a national context of cost-free ART treatment, a large proportion of women did not access treatment, with a strong social gradient that raises important issues. We need to understand the underlying social mechanisms to develop an efficient and equitable health policy regarding infertility care.

[Medical treatments for male infertility]. / Traitements médicaux de l'homme infertile.

BACKGROUND: Treatments to stimulate spermatogenesis and antioxidant food supplements are often offered to infertile patients either before sperm extraction surgery to improve results, or as part of medically assisted reproduction or spontaneous fertility to increase the likelihood of a live birth. METHODS: A bibliographic search limited to English-language literature on men published before 5/2023 was carried out, including clinical trials, literature reviews and meta-analyses on spermatogenesis-stimulating molecules and antioxidant treatments. RESULTS: Several medical treatments seem capable of improving male fertility: they act mainly by stimulating spermatogenesis through hormones, or by reducing the effects of oxidative stress. With regard to oligoasthenozoospermia, the literature shows that certain hormonal treatments stimulating spermatogenesis are useful. In the case of non-obstructive azoospermia, the value of treatment depends on the patient's FSH and testosterone levels. AOX supplementation appears to improve certain spermogram parameters and have an impact on pregnancy and live birth rates. CONCLUSION: This review should help urologists gain a better understanding of the various medical treatments and enable them to define an appropriate therapeutic strategy, tailored to the patient and the couple, in order to obtain the best results.

Heterotopic pregnancy with superfetation following ovarian stimulation: A case report.

Heterotopic pregnancy (HP) is a rare phenomenon. Despite its rarity, there has been a notable increase in its incidence in recent decades due to the greater use of in vitro fertilization (IVF). However, information about the relation between ovarian stimulation and HP is scarce. We report a case of HP after ovarian stimulation using clomiphene citrate. A 26-year-old pregnant woman presented to the emergency department with mild vaginal bleeding, and abdominal pain. She had a history of pelvic inflammatory disease (PID) and left salpingectomy due to a previous ectopic pregnancy. She had undergone ovarian stimulation with clomiphene citrate three months earlier. Transvaginal ultrasound revealed an eight-week-old ruptured tubal pregnancy with an intrauterine ten-week-old gestational sac confirming superfetation HP. An urgent laparoscopic right salpingectomy was performed and the extrauterine pregnancy was successfully removed with the preservation of the intrauterine embryo. The course of the intrauterine pregnancy was uneventful and the patient gave birth to a healthy boy via cesarean section. Women receiving ovarian stimulation are at an increased risk of developing HP especially when they also have other predisposing factors for HP. Thus, close monitoring using transvaginal ultrasound with extra attention to the adnexa is required for a timely diagnosis and management of HP.

Association between follicle size, endometrial thickness, and types of ovarian stimulation (Clomiphene citrate and Letrozole) with biochemical pregnancy rate in women undergone intrauterine insemination.

OBJECTIVE: There was also a lack of data regarding the effect of follicle size, endometrial thickness, and ovarian stimulation as predictors of intrauterine insemination (IUI) success rate in Indonesia, especially in the Aster Clinic and Bandung Fertility Centre. This study was performed to explore the relationship between follicle size, endometrial thickness, and types of ovarian stimulation (Clomiphene citrate/CC vs Letrozole) with biochemical pregnancy rate in women undergone IUI. We performed a case-control study in 122 women aged 20-40 years with unexplained infertility who had completed the IUI program for a maximum of three cycles. Data were extracted from medical records. Independent T-test and multivariate analyses were used to analyse the difference between variables using IBM SPSS 24.0. P-value < 0.05 was considered statistically significant. RESULT: Follicle sizes of 18-22 mm in both Clomiphene citrate (CC) and Letrozole groups were shown to increase biochemical pregnancy rate (P = 0.001). There is no relationship between endometrial thickness and pregnancy rate. Biochemical pregnancy rate in women using Letrozole was 1.513 times higher than women using CC. The follicle size of 18-22 mm and using Letrozole rather than CC as ovarian stimulators are predictive factors associated with a higher pregnancy rate in women undergone IUI.

Effect of Clomiphene Citrate on the Ultrastructure of Testis in Albino Rats

SUMMARY: The aim of the present work was to study the closer effect of clomiphene citrate on the ultrastructure of the testis of adult albino rats to provide a basis for optimizing this drug in the treatment of male infertility. The testes were removed from both groups under anesthesia and then prepared for examination by light using hematoxylin and eosin stains and a transmission electron microscope. Semithin sections were cut into 1 µm thick sections, stained with toluidine blue, and examined by light microscopy for a survey. The desired areas were placed in the center, and other areas were trimmed. Primary spermatocytes showed marked nuclear changes (pyknosis), and their nuclear membranes were ill-defined and disrupted. The cytoplasm showed widespread degeneration of mitochondria and lysosomes and focal degeneration of the rough endoplasmic reticulum compared with the control group. The spermatids were pale, and the two phases of spermatogenesis were distinctly identifiable in the control group but were confused in the treated group. Some spermatids had interrupted nuclear membranes, also containing degenerated mitochondria, focal fragmentation of rough endoplasmic reticulum, and free ribosomes. Spermatozoa in the treated group appeared deformed compared to the control, where they had deformed head caps. Leydig cells of the treated group have an irregularly shaped nucleus, with focal chromatin aggregation and peripheral chromatin condensation on the inner surface of the nuclear membrane. The observations of the present work indicate a possible causal relationship between testicular affection and ingestion of clomiphene citrate, which can be avoided by close medical observations using ultrasonography, semen analysis, or testicular biopsy to detect early malignant changes. Furthermore, the drug should not be used for more than three to six cycles and should be stopped for at least three cycles before reuse. When clomiphene citrate is ineffective in the treatment of male infertility, human menopausal gonadotropin (hMG) administration is typically selected. However, high-dose hMG therapy is associated with a variety of adverse effects. In this work, we report the success of a modified clomiphene citrate regimen in increasing sperm count without any hazards to the testicular tissue.

El objetivo del trabajo fue estudiar el efecto del citrato de clomifeno sobre la estructura de los testículos de la rata albina adulta, con la finalidad de determinar la mejor manera de utilizar este fármaco en el tratamiento de la infertilidad masculina. Los testículos se extrajeron bajo anestesia y para su análisis a través de microscopio de luz se tiñeron con HE. Además, las muestras fueron preparadas para su examen con microscopía electrónica de transmisión. Por otra parte, se cortaron secciones semifinas de 1 µm de espesor, se tiñeron con azul de toluidina y se examinaron mediante microscopía óptica. Los espermatocitos primarios mostraron cambios nucleares marcados (picnosis) y sus membranas nucleares estaban mal definidas y alteradas. En el grupo experimental las células presentaban el citoplasma con degeneración generalizada de las mitocondrias y de los lisosomas y una degeneración focal del retículo endoplásmico rugoso en comparación con el grupo control. Las espermátidas estaban pálidas y las dos fases de la espermatogénesis eran claramente identificables en el grupo control, pero se confundían en el grupo tratado. Algunas espermátidas tenían membranas nucleares interrumpidas, y también contenían mitocondrias degeneradas, fragmentación focal del retículo endoplásmico rugoso y ribosomas libres. Los espermatozoides del grupo tratado se presentaban deformados en comparación con el control. Las células de Leydig del grupo tratado presentaban un núcleo de forma irregular, con agregación focal de cromatina y condensación de cromatina periférica en la superficie interna de la membrana nuclear. Las observaciones del presente trabajo indican una posible relación causal entre la afección testicular y la ingestión de citrato de clomifeno, que puede evitarse mediante observaciones médicas minuciosas a través de ecografía, análisis de semen o biopsia testicular para detectar cambios malignos tempranos. Además, el medicamento no debiera ser usado durante más de tres a seis ciclos y debe suspenderse durante al menos tres ciclos antes de volver a usarlo. Cuando el citrato de clomifeno es ineficaz en el tratamiento de la infertilidad masculina, normalmente se selecciona la administración de gonadotropina menopáusica humana (hMG). Sin embargo, la terapia con hMG en dosis altas se asocia con una variedad de efectos adversos. En este trabajo, informamos el éxito de un régimen modificado con citrato de clomifeno para aumentar el recuento de espermatozoides sin riesgo para el tejido testicular.

Is the Co-administration of Metformin and Clomiphene Superior to Induce Ovulation in Infertile Patients With Poly Cystic Ovary Syndrome and Confirmed Insulin-Resistance: A Double Blind Randomized Clinical Trial.

Objective: This study aimed to compare the effects of clomiphene citrate (CC) combined with metformin or placebo on infertile patients with poly cystic ovary syndrome (PCOS) and insulin resistance (IR). Materials and methods: We included 151 infertile women with PCOS and IR in a university hospital from November 2015 to April 2022 in this prospective, double-blind, randomized, placebo-controlled trial. Patients were randomized into two groups; group A: received CC plus metformin (n = 76) and group B: received CC plus placebo (n = 75). The ovulation rate was the main outcome measure. Clinical pregnancy, ongoing pregnancy, live birth and abortion rates were secondary outcome measures. Results: There was no remarkable difference in ovulation rate in two groups. Moreover, no significant changes were observed in clinical pregnancy, ongoing pregnancy, live birth and abortion rates between two groups. A larger proportion of women in group A suffered from side effects of metformin (9.3% versus 1.4%; p=0.064), although this was not significant. Conclusion: In IR infertile women with PCOS, metformin pre-treatment did not increase the ovulation, clinical pregnancy and live birth rates in patients on clomiphene citrate.
