Objective:
To evaluate obstetric complications in women who conceived through donated oocytes compared with women who conceived through assisted reproduction using autologous oocytes.
Design:
Retrospective cohort analysis.
Setting:
Stanford Hospital and Clinics and Lucille Packard Children's hospital, both tertiary referral centers.
Patient(S):
A cohort of 71 oocyte recipients who underwent in vitro fertilization (IVF) were compared to all women over 38 years who conceived through IVF with autologous oocytes (n = 108) between January 1, 2001, and December 31, 2005, at Stanford University and subsequently delivered infants at Lucille Packard Children's Hospital.
Intervention(S):
Assisted reproductive technology with donor oocytes.
Main Outcome Measure(S):
Obstetric charts of the donor-oocyte recipients were compared for all women over 38 years old who had conceived through IVF with autologous oocytes at the same center (n = 108) and delivered at the same hospital during the same time period. Perinatal complications including preeclampsia, diabetes, preterm labor, preterm premature rupture of membranes and placental abnormalities, mode of delivery, presentation, Apgar scores, gestational age at delivery, and weight were compared between the groups.
Result(S):
Oocyte recipients and autologous oocyte controls had similar rates of complications of prematurity, hypertensive disorders of pregnancy, gestational diabetes, and placental abnormalities. Infant birth weights and gestational age at time of delivery were similar between the two groups.
Conclusion(S):
This study suggests that women undergoing IVF with donor oocytes are not at increased risk for complications during pregnancy or at increased immediate neonatal complications compared with women of advanced maternal age undergoing IVF with autologous oocytes.
