目的:探讨剖宫产术后瘢痕子宫对辅助生殖助孕策略的影响。方法:回顾性分析2017年1月1日至12月31日本院行体外受精-胚胎移植(IVF-ET)助孕鲜胚移植的瘢痕子宫组109例和阴道分娩史组63例患者的病例资料，比较两组患者的超促排效果和妊娠结局。结果:⑴年龄0.05)，但瘢痕子宫组患者获卵数、成熟卵子数、2PN数、优良胚胎数与阴道分娩史组患者比较差异均有统计学意义(n P0.05)。⑵年龄0.05)。但是移植两枚胚胎时，瘢痕子宫组患者临床妊娠率、胚胎着床率均稍低于阴道分娩史组患者(57.57% vs 71.05%，39.39% vs 47.37%)，差异无统计学意义(n P>0.05)。年龄≥35岁的患者中，单胚胎移植和双胚胎移植的临床妊娠率、胚胎着床率差异均无统计学意义(n P>0.05)。⑶年龄0.05)。n 结论:剖宫产手术后IVF助孕可能会影响患者获卵数和成熟卵数，既往剖宫产手术史的患者，再生育前建议尽早评估卵巢功能，必要时积极助孕。单胚胎移植并不降低剖宫产瘢痕子宫患者IVF-ET助孕结局，建议剖宫产瘢痕子宫患者行单胚胎移植，降低双胎妊娠后孕产期风险。“,”Objective:To investigate the effect of scar uterus on assisted reproduction treatment strategy.Methods:From January 1, 2017 to December 31, 2017, 109 cases of scar uterus group and 63 cases of vaginal delivery history group who underwent in n vitro fertilization-embryo transfer (IVF-ET) assisted pregnancy fresh embryo transfer in our hospital were retrospectively analyzed.n Results:⑴ There was no significant difference in the total amount of gonadotropin (Gn) and the total days of GN in patients 0.05), but there were significant differences in the number of oocytes, mature oocytes, two pronucleus (2PN) and excellent embryos between the scar uterus group and the vaginal delivery history group (n P0.05). ⑵ There were no statistically significant differences in clinical pregnancy rate and embryo implantation rate between the two groups of patients 0.05). There were no statistically significant differences in the clinical pregnancy rate and embryo implantation rate between single embryo transplantation and double embryo transplantation in patients≥35 years old (n P>0.05). ⑶ There were no statistically differences in biochemical pregnancy rate, early abortion rate, preterm birth rate and average newborn weight between the scar uterus group and the vaginal delivery history group (n P>0.05).n Conclusions:Cesarean section may affect the ovarian function. For patients with previous cesarean section, early evaluation of ovarian function is recommended. Single embryo transfer does not reduce the outcome in IVF-ET. It is recommended to perform single embryo transfer for patients with scar uterus to reduce the risk during pregnancy of twin pregnancy.
