PP079. Ovarian reserve and function is preserved following severe preeclampsia

Preeclampsia is a multi-organ disorder that predominantly affects renal, cardiovascular, and endocrine systems with long-term consequences for the women's health. As advanced age and history of subfertility increase the risk of developing preeclampsia, reduced ovarian reserve may be associated with preeclampsia. However, long-term effect of preeclampsia on the ovarian function and reserve is not known. We hypothesized that the ovarian reserve and function are reduced in women with a previous history of severe preeclampsia.

To compare the plasma levels of markers of ovarian function (FSH, LH, SHBG, testosterone) and reserve (anti-Müllerian hormone, AMH) in women who previously had preeclampsia with their matched controls.

Twenty women who had severe preeclampsia (PE group) requiring delivery before 36 weeks of gestation and 20 controls were matched for age, parity, height and weight were included in the study. Women were not breast-feeding, they were having regular menstrual periods and were not using any hormonal contraception. Fasting blood samples were taken during the follicular phase. Plasma was separated and frozen at -70 degrees until analyzed. Comparison between groups was performed using paired sample t-test for parametric and Wilcoxon T-test for nonparametric data. A two-tailed p-value <0.05 was considered significant.

The mean age was 36.4 years, height 164cm and weight 72kg in PE group, compared to 37.0 years, 165cm and 69kg, respectively in control group. The mean AMH was 1.34ng/mL in PE group compared to 1.55ng/mL in controls (p=NS). No significant differences were found in the levels of LH (6.72 versus 6.53 IU/L), FSH (5.27 versus 7.16 IU/L), LH/FSH ratio (1.39 versus 1.11), SHBG (63.65 versus 52.90 versus 52.90nmol/L), and testosterone (0.72 versus 1.01nmol/L) between groups.

Ovarian reserve and function is not altered significantly in women with a previous history of preeclampsia.
