Evaluation of ovarian function in 35–40-year-old women with polycystic ovary syndrome

Abstract Objective To assess gonadotrophin secretion, ovarian steroid production and ovarian reserve in PCOS women during the onset of reproductive decline, in order to characterize their ovarian function at this age. Study design Forty PCOS patients and 35 healthy women (35–40 years of age) were included. Clinical history, anthropometry, transvaginal ultrasound and a leuprolide acetate test (10 μg/kg s.c.) were performed. Gonadotrophins, steroid hormones, SHBG, inhibin B and AMH were determined. Results Basal and peak LH levels were similar in both groups. Basal and peak FSH levels were significantly higher in the control group. Androgens, peak oestradiol, ovarian volume, antral follicle count and AMH levels were significantly higher in PCOS patients. Conclusion These observations suggest that during late reproductive age, gonadotrophin secretion in women with PCOS is clearly different from that observed in control women and may also differ from that of younger PCOS patients. New features like normal LH and lower FSH levels associated with a higher ovarian reserve may give a different reproductive profile to these women.
