Does AMH Reflect Follicle Number Similarly in Women with and without PCOS?

Abstract

Increased Anti-Mullerian Hormone in polycystic ovary syndrome, may be due to overactive follicles rather than reflect antral follicle count.Does Anti-Mullerian Hormone reflect antral follicle count similarly in women with or without polycystic ovary syndrome or polycystic ovarian morphology?Cross-sectional, case-control.Women who delivered preterm in 1999-2006. For each index woman, a woman with a term delivery was identified.Participation rate was 69%. Between 2006-2008, 262 women were included, and diagnosed to have polycystic ovary syndrome, polycystic ovarian morphology or to be normal controls.Blood tests, a clinical examination and vaginal ultrasound.Anti-Mullerian Hormone/antral follicle count-ratio, SHBG, androstenedione and insulin, to test potential influence on the Anti-Mullerian Hormone/antral follicle count -ratio.Mean Anti-Mullerian Hormone/antral follicle count ratio in women with polycystic ovary syndrome or polycystic ovarian morphology was similar to that of the controls (polycystic ovary syndrome: 1,2 p = 0,10 polycystic ovarian morphology: 1,2, p = 0,27 Controls 1,3). Anti-Mullerian Hormone showed a positive linear correlation to antral follicle count in all groups. Multivariate analysis did not change the results.We confirmed the positive correlation between AMH and follicle count. Anti-Mullerian Hormone seems to be a reliable predictor of antral follicle count, independent of polycystic ovary syndrome diagnosis or ovarian morphology.
