确定既往剖宫产史（CD）是否使胚胎移植更加困难并影响妊娠结局。前瞻性队列研究三级医疗军事设施中的不孕症实践194例既往分娩的患者接受IVF/ICSI-ET无活产（初次），hCG阳性，临床妊娠和进行胚胎移植的时间仅阴道分娩史的患者与有CD病史的患者之间的活产无统计学显著差异（39% vs. 32%）、hCG阳性（56% vs. 53%）或临床妊娠（49% vs. 41%）。CD组的胚胎移植时间更长（157秒对187秒），导管上更有可能有粘液（27%对45%）或血液（8%对21%）。对先前患有CD的患者进行胚胎移植需要多花30秒。他们也更有可能在导管上有血液或粘液。尽管转移明显更困难，但两组之间的妊娠结局没有差异。
To determine if a history of prior Cesarean delivery (CD) makes embryo transfer more difficult and impacts pregnancy outcomes. Prospective cohort study Infertility practice in a Tertiary Care Military Facility One hundred ninety-four patients with previous delivery undergoing IVF/ICSI-ET None Live birth (primary), positive hCG, clinical pregnancy, and time to perform embryo transfer There was no statistically significant difference between patients with a history of only vaginal deliveries versus those with a history of CD for live birth (39% vs. 32%), positive hCG (56% vs. 53%), or clinical pregnancy (49% vs. 41%). Embryo transfers took longer in the history of CD group (157 vs. 187 seconds) and were more likely to have mucus (27% vs. 45%) or blood (8% vs. 21%) on the catheter. Embryo transfers performed on patients with a prior CD took 30 seconds longer. They were also more likely to have blood or mucus on the catheter. Despite the apparently more difficult transfers, pregnancy outcomes were not different between the two groups.
