近年来由于冷冻保存胚胎的进展,为子宫内和输卵管内胚胎输送,在一个诱发排卵周期能获得超量的卵子进行受精和冷冻,可有力地降低病人妊娠所需卵巢过度刺激周期的次数及较低的生物学和经济负担。于是对配子输卵管内输送(GIFT)一个大组的结果进行回顾性分析并评价其临床妊娠率(PRS)与输送卵母细胞数量的关系。 1987年7月1日～1988年12月31日共进行586个GIFT周期,所有病人均在对配偶双方综合估价后选择,且皆为多种常规治疗失败者。诊断包括不孕继发于子宫内膜异位症、输卵管因素、排卵功能障碍、子宫肌瘤、宫颈因素,男性因素以及不明原因和免疫学不孕。根据病人情况确定诱发排卵方
In recent years due to the progress of cryopreserved embryos, intrauterine and intra-tubal embryo delivery, in an induced ovulation cycle to obtain excess of eggs for fertilization and freezing, can effectively reduce the number of ovarian hyperstimulation cycles required for pregnancy and more Low biological and financial burden. The results of a large group of gamete intra-tubal delivery (GIFT) were then retrospectively analyzed and the relationship between their clinical pregnancy rate (PRS) and the number of oocytes delivered was assessed. From July 1, 1987 to December 31, 1988, a total of 586 GIFT cycles were performed. All patients were selected after comprehensive evaluation of both spouses, and all were routine losers. Diagnosis includes infertility secondary to endometriosis, tubal factors, ovulation dysfunction, uterine fibroids, cervical factors, male factors and unexplained and immunological infertility. According to the patient to determine the induced ovulation side
