Abstract Background: Whether treatment with oral contraceptives (OC) and metformin can reduce anti-Müllerian hormone (AMH) levels in PCOS remains controversial. This study aims to investigate the effects of OC and metformin on serum AMH concentrations in women with polycystic ovary syndrome (PCOS). Methods: This prospective study included 120 women with PCOS. Patients were treated with OC (35 μg of ethinyl estradiol plus 2 mg of cyproterone acetate), metformin, or OC plus metformin for 3 months according to their different endocrine/metabolic disturbances. Forty-eight patients with hyperandrogenism (HA) were treated with OC, 32 patients with insulin resistance (IR) were treated with metformin, and 40 patients with HA and IR were treated with a combination of OC and metformin. Serum AMH levels were compared before and after treatment within each group.Results: AMH levels decreased significantly in both OC groups (from 12.54 ± 5.59 ng/mL before treatment to 9.03 ± 4.49 ng/mL after treatment, P < 0.01) as well as in the OC + metformin group (from 10.62 ± 4.57 ng/mL to 7.74 ± 3.19 ng/mL, P < 0.01). However, AMH concentrations remained unchanged in the metformin group, although insulin sensitivity was improved. Conclusion: Treatment with OC alone or OC plus metformin led to a significant reduction of serum AMH in PCOS patients with HA, while metformin treatment alone did not affect AMH levels in patients with IR.

OBJECTIVE: To evaluate adrenal and ovarian steroidogenesis before and after long-term treatment with metformin in women with polycystic ovary syndrome (PCOS). DESIGN AND METHODS: Twenty-four women with PCOS were evaluated before and after treatment (27+/-4 weeks) with metformin (1000 mg/day) using adrenocorticotrophin (ACTH), GnRH analogue and oral glucose tolerance (oGTT) tests. For statistical evaluation, ANOVA and Wilcoxon's test were used. RESULTS: In 58% of the women a significant improvement in menstrual cyclicity was observed. No significant change in basal steroid levels was found. After ACTH stimulation, a significant decrease in the activity of 3 beta-hydroxysteroid dehydrogenase in C(21) steroids (P<0.05) and in 17 beta-hydroxysteroid dehydrogenase (P<0.01) was observed, as was an increase in the activity of C17,20-lyase in the Delta(4) pathway (P<0.01). A significant growth in the dehydroepiandrosterone (DHEA)/DHEA-sulfate ratio (P<0.05) was detected. With regard to ovarian steroidogenesis, a significant decrease in the stimulated levels of testosterone (P<0.05), index of free testosterone (P<0.01), LH (P<0.05) and oestradiol (P<0.01), and an increase in the levels of 17-hydroxypregnenolone (P<0.05) were detected. In the indices of ovarian enzyme activities, we observed a significant decrease in 3 beta-hydroxysteroid dehydrogenase in C21 steroids (P<0.01), in C17,20-lyase in the Delta 5 pathway (P<0.01), in 17 beta-hydroxysteroid dehydrogenase (P<0.05) and in aromatase. In glucose metabolism, a tendency towards reduction in the homeostasis model assessment (HOMA)-R (for insulin resistance) and HOMA-F (for beta cell function) was detected. In addition, an increase in the levels of C peptide during oGTT was observed (P<0.01). CONCLUSIONS: Long-term metformin treatment reduced various steroid enzymatic activities both in the ovary and the adrenal glands, without apparent changes in basal steroid levels and in insulin sensitivity.
