This study examined oocyte and embryo quality in patients having excessive ovarian responses during assisted reproduction treatment.
Two hundred and seventy-eight women of age <40 years using a long protocol of pituitary downregulation in their first intracytoplasmic sperm injection cycle indicated for severe male factors were retrospectively evaluated. Those with serum estradiol concentration on the day of HCG <10,000, 10,000-20,000, and >20,000 pmol/L were classified into Group A, Group B, and Group C, respectively.
The percentage of metaphase II oocytes (85%), fertilization rate (60-66%), and distribution of blastomere number per embryo were similar among the three groups. The proportion of transferable embryos was not reduced in Group C when compared to those of Groups A and B.
Excessive ovarian response does not compromise oocyte and embryo quality in humans. Freezing of all embryos is recommended in these patients in view of associated impaired endometrial receptivity.
本研究探讨了辅助生殖治疗期间卵巢反应过度患者的卵母细胞和胚胎质量。
回顾性评估了278名年龄<40岁、在首次因严重男性因素而行卵胞浆内单精子注射周期中采用垂体降调节长方案的女性。将人绒毛膜促性腺激素(HCG)日血清雌二醇浓度<10,000、10,000 - 20,000和>20,000 pmol/L的患者分别分为A组、B组和C组。
三组间中期II卵母细胞百分比(85%)、受精率(60 - 66%)以及每个胚胎的卵裂球数量分布相似。与A组和B组相比,C组可移植胚胎的比例并未降低。
卵巢过度反应不会损害人类卵母细胞和胚胎质量。鉴于这些患者存在子宫内膜容受性受损,建议对所有胚胎进行冷冻。
