Relationship of serum anti-Müllerian hormone, inhibin B, estradiol and FSH on day 3 with ovarian follicular status |

PURPOSE: to examine the hypothesis that serum anti-Müllerian hormone (AMH) levels reflect the ovarian follicular status. METHODS: Design: prospective study. Patients: we studied 101 IVF-ET candidates undergoing controlled ovarian hyperstimulation with GnRH agonist and FSH. After the achievement of pituitary suppression and before FSH administration (baseline), serum AMH, inhibin B, and FSH levels were measured. The number of antral follicles was determined by ultrasound at baseline (early antral follicles; 3-10 mm). RESULTS: at baseline, median serum levels of AMH, inhibin B, E2, P4 and FSH were 3.42±0.14 ng/mL, 89±4.8 pg/mL, 34±2.7 pg/mL, 0.22±0.23 ng/mL and 6.6±0.1 mIU/mL, respectively, and the mean number of early antral follicles was 17±0.39. Serum levels of AMH were negatively correlated with age (r=-0.19, p<0.04), and positively correlated with number of antral follicles (r=0.65, p<0.0001), but this did not apply to serum levels of either inhibin B, E2 or FSH. CONCLUSION: the data demonstrate an association between AMH and antral follicular counts. Therefore, AMH is probable a biomarker of ovarian follicular status.
