Relations between steroids and AMH: impact of basal and intrafollicular steroids to AMH ratios on oocyte yield and maturation rate in women with or without polycystic ovary undergoing in vitro fertilization.
ABSTRACT This study sought to determine the relationships between serum or intrafollicular ovarian steroids and anti-mullerian hormone (AMH) and to predict impact of steroids to AMH ratios on oocyte quantity and metaphase II (MII) oocyte rate in normo-ovulatory (control) and polycystic ovary syndrome (PCOS) patients.
University hospital and research center.
Thirty-two patients with PCOS and 37 controls undergoing IVF-ET.
Serum (day 3) and follicular fluid (FF) from more than one follicle ≥ 17 mm on the day of oocyte retrieval were collected from each patients.
Serum or follicular fluid steroids, AMH, retrieved oocytes number and maturation rate.
In control group, intrafollicular AMH levels were positively related to P4 and T levels (p = .002, p = .011, respectively). Multiple linear regression analysis showed serum basal AMH and T levels as independent positive predictors while T/AMH ratio and intrafollicular AMH were negative predictors for both retrieved and MII oocyte number. The presence of PCOS and intrafollicular P4/AMH ratio revealed as important negative factors influencing oocyte maturation rate.
Serum basal T, AMH as well as their ratio and intrafollicular P4/AMH ratio may be used as predictors for retrieved oocyte number and their nuclear maturation rate, respectively.
