Abstract:
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 vitro fertilization-embryo transfer (IVF-ET) assisted pregnancy fresh embryo transfer in our hospital were retrospectively analyzed. Results:⑴ There was no significant difference in the total amount of gonadotropin (Gn) and the total days of GN in patients <35 between scar uterus group and the vaginal delivery history group ( P>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 ( P<0.05). When the age was ≥35 years old, there was no significant difference in the total number of GN, the total days of GN, the number of oocytes obtained, the number of mature oocytes, the number of 2PN and the number of excellent embryos between the two groups ( P>0.05). ⑵ There were no statistically significant differences in clinical pregnancy rate and embryo implantation rate between the two groups of patients < 35 years old, no matter single embryo transplantation or double embryos transplantation. When transplant two embryos, the clinical pregnancy rate and embryo implantation rate in the scar uterus group were slightly lower than those in the vaginal delivery history group (57.57% vs 71.05% and 39.39% vs 47.37%, respectively), but with no significant difference ( P>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 ( 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 ( P>0.05). 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.
