The purpose was to determine whether the number of embryos available for transfer following IVF in women over age 39 predicted a successful pregnancy outcome.
Retrospective analysis of 455 consecutive IVF cycles in women > or = 40 years of age.
Few cycles were canceled (29/455, 6.4%) or produced no embryos (5/455, 1.1%). Women 40-43 years of age with normal ovarian reserve had a significantly greater delivery rate when > or = 4 embryos were available for transfer than when < 4 embryos were available (17.8% versus 2.4%, P = 0.002). Subsequent IVF cycles, from women with normal FSH whose first cycle produced < 4 embryos, produced delivery rates of 13.0% when > or = 4 embryos were available. Women with abnormal ovarian reserve or age > or = 44 years had very low delivery rates (1.2% and 1.4% respectively).
The number of embryos available for transfer significantly predicts delivery from IVF-ET among reproductively older women. Many women age 40-43 with normal ovarian reserve can achieve pregnancy through IVF.
本研究旨在确定39岁以上女性体外受精(IVF)后可用于移植的胚胎数量是否能预测妊娠成功结局。
对455例年龄大于或等于40岁女性的连续IVF周期进行回顾性分析。
很少有周期被取消(29/455,6.4%)或未产生胚胎(5/455,1.1%)。卵巢储备功能正常的40 - 43岁女性,当有大于或等于4个胚胎可用于移植时,其分娩率显著高于可用于移植的胚胎小于4个时(17.8%对2.4%,P = 0.002)。对于促卵泡生成素(FSH)正常且首个周期产生的胚胎小于4个的女性,随后的IVF周期中,当有大于或等于4个胚胎可用于移植时,分娩率为13.0%。卵巢储备功能异常或年龄大于或等于44岁的女性分娩率非常低(分别为1.2%和1.4%)。
可用于移植的胚胎数量能显著预测高龄女性IVF - ET后的分娩情况。许多卵巢储备功能正常的40 - 43岁女性可通过IVF实现妊娠。
