Ovarian response patterns to human menopausal gonadotropin in mixed hyperandrogenemia

Area of Science:

• Reproductive Endocrinology
• Infertility Research
• Gynecology

Background:

• Hyperandrogenism is a common cause of infertility in women with chronic anovulation.
• Polycystic ovarian morphology and elevated androgens are key features, but presentation varies.
• Understanding ovarian response to stimulation is crucial for managing infertility.

Purpose of the Study:

• To investigate the ovarian response to human menopausal gonadotropin (hMG) in hyperandrogenemic women with infertility.
• To differentiate follicular development patterns and their correlation with ovarian morphology and androgen levels.
• To explore the potential for identifying borderline polycystic ovaries and inherent ovarian failure.

Main Methods:

• Treatment of 28 hyperandrogenemic infertile women with hMG.
• Assessment of ovarian volume, LH/FSH ratio, and circulating androgens (ovarian and adrenal).
• Dexamethasone suppression testing to evaluate androgen origins.
• Categorization of follicular development patterns post-hMG stimulation.

Main Results:

• Two distinct follicular development patterns were observed: polycystic ovarian reaction (16 patients) and normo-ovulatory pattern (12 patients).
• Patients with polycystic ovarian reaction had significantly increased androstenedione response to hMG and larger non-stimulated ovarian volumes.
• Elevated circulating androgens and variable suppression post-dexamethasone were noted, indicating mixed hyperandrogenism.

Conclusions:

• Ovarian stimulation in hyperandrogenemic women can reveal borderline polycystic ovarian disease.
• An increased androstenedione response to hMG may indicate underlying ovarian dysfunction or failure.
• These findings aid in characterizing infertility causes in hyperandrogenemic women.
