Correlation of serum Anti-Müllerian hormone concentrations on day 3 of the in vitro fertilization stimulation cycle with assisted reproduction outcome in polycystic ovary syndrome patients

To investigate whether serum Anti- Müllerian hormone (AMH) on day 3 could predict controlled ovarian stimulation and reproductive outcomes in women with polycystic ovary syndrome.

A total of 164 PCOS patients undergoing their first IVF treatment cycle were prospectively included. Serum AMH levels on cycle day 3 was measured. The controlled ovarian stimulation and clinical outcomes for the study population were divided according to the <25th, 25 to 75th, or >75th percentile of serum day-3 AMH.

Estradiol levels on hCG day and the number of retrieved oocytes significantly increased with increasing serum AMH levels, while total consumption of gonadotropin dose showed a significant decrease (P < 0.05). Fertilization rate and the number of good quality embryos were comparable among the low, average and high groups (P > 0.05). Embryo implantation rates in the high AMH group was significantly inferior to those with low and average AMH concentration (27 versus 48.8 and 50%, P < 0.01). Clinical pregnancy rates was lower in the high AMH group than that of the low and average group (45.9 versus 65 and 66.7%, P = 0.09), but this difference was only close to statistical significance. In addition, ordinal regression analysis indicated that LH level was the only independent predictor of embryo implantation rates (P = 0.017).

In PCOS women, AMH levels on day 3 of the IVF stimulation cycle positively predict ovarian response to gonadotrophins. However, the women with high AMH levels had a significantly decreased IR, which may be due to remarkably increased LH concentrations.
