BACKGROUND: Pre-eclampsia affects 2–10% of all pregnancies and is a major cause of maternal and fetal morbidity and mortality. As compared with the general population, IVF pregnancies are associated with a 2.7-fold risk of pre-eclampsia. An advanced age and associated subfertility in the IVF group reflects a general decrease in ovarian reserve, which itself has been linked to cardiovascular disease. We tested the hypothesis that decreased ovarian reserve is associated with pre-eclampsia as a vascular complication in IVF/ICSI pregnancies. METHODS: In this retrospective case–control study, 41 cases with a history of pre-eclampsia were compared to 82 matched controls without hypertension or (pre)eclampsia. All pregnancies were established after IVF or ICSI. Several indicators of ovarian reserve such as variables related to basal ovarian function and response to hyperstimulation were compared in both the groups by multivariate analysis. The condition of the neonates was evaluated as well. RESULTS: A higher amount of total administered FSH and FSH per day, together with a lower number of obtained oocytes during IVF treatment, were associated with an increased risk to pre-eclampsia in a subsequent pregnancy. The administered FSH per follicle and per obtained oocyte showed even stronger relationships, the latter having the best predictive value. Neonatal outcome was comparable between the groups. CONCLUSION: Diminished responsiveness of the ovaries to FSH stimulation in an IVF cycle, reflecting decreased ovarian reserve, is associated with an increased risk of developing pre-eclampsia in a subsequent pregnancy.
