Outcomes of pregnancies achieved by double gamete donation: A comparison with pregnancies obtained by oocyte donation alone.

Objective: Women increasingly resort to oocyte donation to become pregnant. The high risk of preeclampsia found in oocyte donation pregnancies and the separate risk of preeclampsia associated with sperm donation may be cumulative in double donation pregnancies. We aimed to study the obstetrical and perinatal outcomes of pregnancies obtained by double donation (both oocyte and sperm) in comparison with those obtained by oocyte donation alone (oocyte donation and partner's sperm).

Oocyte donation recipients of very advanced age: perinatal complications for singletons and twins.

Objective: To compare maternal, obstetric, and neonatal outcomes between women who underwent oocyte donation at or after age 50 years and from 45 through 49 years.

Design: Single-center, retrospective cohort study.

Setting: Maternity hospital.
