AI Article Synopsis

  • The study presents three cases of men who experienced azoospermia (absence of sperm) after taking clomiphene citrate (CC) for previously diagnosed oligospermia (low sperm count).
  • The patients initially had low sperm concentrations and showed no sperm in their semen analyses following CC treatment.
  • After discontinuing CC for three months, their sperm concentration improved slightly but remained below normal levels, highlighting the potential risks of using CC.

Article Abstract

Objective: To describe three cases of azoospermia in patients with oligospermia after clomiphene citrate (CC) intake.

Design: Case report.

Setting(s): Academic medical center.

Patient(s): Three patients with oligospermia.

Intervention(s): Three oligospermic men used CC, resulting in azoospermia.

Main Outcome Measure(s): Semen analysis after CC use and after discontinuation of CC.

Result(s): Three patients were sent to our clinic for investigation of their azoospermia after use of CC. They had severe oligozoospermia (sperm concentrations of 3.4, 2.8, and 4.1 x 10(6)/mL, respectively) before treatment with CC. These patients were re-evaluated with two new semen analyses, showing azoospermia. After 3 months without use of the drug, the mean sperm concentration was 2.5 +/- 1.1 x 10(6)/mL.

Conclusion(s): The benefits of empiric treatment with CC must be balanced with the possible undesirable effects, such as azoospermia.

PCOS is a common endocrine disorder in women particularly in their reproductive age. GABA has been implicated in the pathogenesis of PCOS through its central role in the hypothalamus. Hence, in this study we investigated the effect of Nipecotic acid (NPA) in Letrozole induced PCOS in female Wistar rats as NPA has been proven as a GABA uptake inhibitor.

Objective: To explore whether acupuncture combined with clomiphene can reduce the luteinizing hormone-to follicle-stimulating hormone ratio and impact the gut microbiota in patients with obese polycystic ovary syndrome.

Methods: This open-label, randomized, parallel-group controlled trial included 86 women aged 20-40 years with obese polycystic ovary syndrome and 19 healthy controls. Participants were randomly assigned to either an acupuncture combined with clomiphene group or a clomiphene-only group, with a healthy control group for comparison.

Purpose: To evaluate the effect of transvaginal ovarian drilling (TVOD) on IVF outcomes in subjects with clomiphene-resistant PCOS and a history of IVF failure.

Methods: Between 2008 and 2011, 19 subjects with sonographically PCOS and a history of failure to ovulate to high-dose clomiphene citrate were prospectively followed and underwent TVOD at a university hospital-based IVF program.

Results: In 15 subjects who underwent 30 fresh paired IVF cycles TVOD resulted in a significantly higher number of oocytes retrieved (7.

Purpose: Clinical trials are advancing the treatment of polycystic ovary syndrome (PCOS), an endocrine disorder affecting 8-13% of women. Lifestyle interventions, including nutritional plans, physical activity, and stress management, can improve reproductive hormones and metabolic health. Novel pharmacotherapies targeting hormonal, metabolic, and reproductive abnormalities are being explored for individualized treatment.
