Inositol Supplementation to Treat PCOS (INSUPP-PCOS)

To determine if Inositol, a dietary supplement, will improve ovarian and adrenal androgen excess in women with Polycystic Ovarian Syndrome(PCOS).

Half-dose vs Conventional-dose Cetrorelix in ICSI Cycles

This prospective cohort study aims to compare the effectiveness of half-dose (0.125 mg/day) versus conventional-dose (0.25 mg/day) cetrorelix in GnRH antagonist ICSI cycles regarding clinical pregnancy rate in women with BMI ≥25 kg/m².

Sperm Preparation Prior to Intrauterine Insemination Study

This is a randomized controlled trial comparing density gradient centrifugation and microfluidic sperm sorting in patients undergoing intrauterine insemination to evaluate cumulative pregnancy outcomes.

Study of Mechanisms of Anovulation in Polycystic Ovary Syndrome

We previously hypothesized that the excess of Anti-Mullerian Hormone (AMH) at the level of ovarian selectable follicles could be involved in the follicular arrest of Polycystic Ovary Syndrome (PCOS), mainly through inhibition of FSH effect on aromatase expression.In this study, we plan to investigate whether a drop in the serum AMH level would be concomitant to the appearance of a dominant follicle induced by administration of mild amounts of exogenous FSH in women with PCOS.

Letrozole Extended vs Traditional Therapy for Ovulation Induction in Women With PCOS (PROLEx-PCOS)

This randomized clinical trial aims to compare the efficacy and safety of extended letrozole therapy (5 mg/day for 10 days) versus standard letrozole therapy (5 mg/day for 5 days) for ovulation induction in women with polycystic ovary syndrome (PCOS). A total of 84 women aged 18-40 years will be randomized into two groups. Ovulation will be monitored by transvaginal ultrasound and confirmed with urinary LH testing and/or corpus luteum presence. The primary outcome is ovulation rate, while secondary outcomes include number and size of mature follicles, clinical pregnancy rate, multiple pregnancy rate, miscarriage rate, number of cycles until pregnancy, and incidence of ovarian hyperstimulation syndrome (OHSS).

Effect of Vitamin D on Ovulation Rate in Women With Polycystic Ovary Syndrome

This is a randomized double-blind controlled trial on the effect of vitamin D supplementation to assess the ovulation rate of women with polycystic ovary syndrome (PCOS) and other reproductive, endocrine and metabolic outcomes after one year of treatment.
