To determine whether there was any difference in the outcome of in vitro fertilization when retrieval of oocytes was done 34 hr (group A) or 38 hr (group B) after hCG injection.
A total of 170 patients with tubal failure were randomized into either group A (83 patients) or group B (87 patients). They underwent in vitro fertilization according to described protocols and were compared with regard to the frequency of spontaneous ovulation, number of oocytes retrieved, oocyte cumulus complex quality, embryo quality, and implantation and pregnancy rates.
There was no significant difference for any of the parameters tested for in group A and group B.
HCG can be administered at any time within the time interval of 34 to 38 hr before retrieval of oocytes without affecting the results of in vitro fertilization.
确定在注射人绒毛膜促性腺激素(hCG)后34小时(A组)或38小时(B组)进行卵母细胞取卵时,体外受精的结果是否存在差异。
总共170例输卵管功能衰竭患者被随机分为A组(83例患者)或B组(87例患者)。他们按照所述方案进行体外受精,并在自发排卵频率、取卵数量、卵母细胞-卵丘复合体质量、胚胎质量以及着床率和妊娠率方面进行比较。
A组和B组所测试的任何参数均无显著差异。
在取卵前34至38小时的时间间隔内,可在任何时间注射hCG,而不会影响体外受精的结果。
