Successful delivery after age 50: a report of two cases as a result of oocyte donation.

Abstract：

BACKGROUND:Because of donor oocyte programs, women who previously were considered too old to successfully achieve conception and delivery can now bear children. To our knowledge, there have been no previous reports of pregnancy outcome in women over age 50 who conceived using donor oocytes. This study presents the pregnancy and delivery data on two women who delivered at age 52. CASES:Case 1 was a 51-year-old woman, gravida 3, para 3, whose three children had been conceived with her first husband more than 20 years previously. She had remarried 18 years before presentation and had been actively trying to conceive for the last 7 years. She was diagnosed as being in menopause based on elevated gonadotropins, amenorrhea, and failure to have progesterone-withdrawal menses. She conceived on her first embryo transfer cycle with embryos derived from donor oocytes and fertilized by her husband's sperm (oocytes were donated by a woman who was undergoing retrieval for in vitro fertilization). During pregnancy she remained healthy, but had uterine prolapse at 20 weeks. She delivered a normal healthy male at 40.5 weeks; cesarean was performed because of a presumptive diagnosis of fetal distress after 3 hours of labor, when monitoring revealed fetal heart decelerations. Case 2 was also a 51-year-old woman, gravida 6, para 4, who wished to conceive with her second husband's sperm through the donor oocyte program. She had amenorrhea of 2 years' duration and elevated gonadotropins. Conception occurred after fertilization of a donor oocyte by her husband's sperm. She had an uneventful pregnancy, but labor was induced at 38 weeks' gestation given the supposed high-risk status of this age group. Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. CONCLUSION:Theoretically, the risks of pregnancy complications in older patients are magnified given the aging maternal cardiovascular system, which may predispose these women to placental insufficiency. These first two cases of donor oocyte pregnancies in women over age 50 found no maternal or fetal age-related complications. We hope these reports will encourage all researchers to share their findings so that prospective patients can make better, more informed decisions as to whether they want to participate in donor oocyte programs.
