短时受精对体外受精妊娠结局的影响
Effect of Short Time Insemination on Outcome of In Vitro Fertilization
摘要
Abstract
[Objective] To assess the effect of short time insemination (2 hours, 2 h) on the polyspermy rate and the outcome of in vitro fertilization (IVF). [Methods] In this prospective study, 658 patients were randomized divided into short time insemination group (group A) and standard insemination group (group B). The rates of fertility, polyspermy, usable embryos, clinical pregnancy and implantation were studied, [outcome] Sixty-one patients of the total participates were excluded because of no embryos available. The data of the other 597 patients were analyzed. There were 294 patients in the short co-incubation group and 303 patients in the standard insemination group. The fertility rate was significantly lower in group A than that in group B (68.8% vs 72.1%, P < 0.05). But the rates of polyspermy (11.4% vs 11.7%, P>0.05), usable embryos (86.5% vs 86.1%, P>0.05), clinical pregnancy (47.6% vs 42.6%, P > 0.05) and implantation (28.6% vs 26.5%, P > 0.05) had no significant differences, [conclusion] 2 h insemination did not improve the polyspermy rate and the outcome of IVF.关键词
