The effect of different hormone therapies on anti-müllerian hormone serum levels in anovulatory women of reproductive age
Abstract
OBJECTIVE: To investigate the effect of oral contraceptives (OC), metformin and ovulation induction with gonadotropins on circulating anti-müllerian hormone (AMH).
DESIGN: Prospective clinical study.
PATIENTS: Thirty patients with PCOS (Group 1), 15 normogonadotropic anovulatory infertile women (WHO 2) (Group 2) and 15 normoovulatory control women (Group 3). Patients in Group 1 received OC (n = 12), metformin (n = 11) or no-treatment (n = 7) for 6 months. Ovulation induction with FSH or hMG was used in Group 2.
MAIN OUTCOME MEASURES: Total follicle number (TFN) and hormonal (fasting insulin and glucose, testosterone, SHBG, LH, androstenedione and AMH) measurements at baseline and during therapy.
RESULTS: Basal AMH and TFN were higher in Groups 1 and 2 than in controls. Only TFN was significantly related to AMH level in Groups 1 and 2. AMH level was significantly reduced during OC treatment, and there was a trend for AMH decrease during metformin therapy. No significant changes in AMH level were observed during ovulation induction. TFN was the only parameter showing a significant positive correlation with circulating AMH over the 6-month treatment period in patients in Group 2.
CONCLUSIONS: AMH is an accurate marker of the antral follicle pool in WHO-2/PCOS women but the measurement of AMH is not likely to be helpful in the management of those patients.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 15 participants or records.
