Abstract:
Objective To assess the effects of artificial cycle after long-acting gonadotropin-releasing hormone (GnRH) agonist down regulation scheme and artificial cycle only scheme in preparation of endometrium before frozen embryo transfer in polycystic ovary syndrome (PCOS) patients on pregnancy outcome.Methods A retrospective analysis was made on the frozen embryo transfer of 132 PCOS patients in the reproductive center of Hunan Maternal and Child Health Hospital from November 2016 to October 2017.The patients were divided into GnRH-a down regulation + artificial cycle group (n =66) and simple artificial cycle group (n =66) according to the different endometrial preparation schemes before frozen embryo transplantation.The transplantation cycle and pregnancy outcome of the two groups were compared.Results (1) There was no statistically significant difference in age,primary infertility rate,infertility years and body mass index (BMI) between the two groups (P > 0.05).(2) In the artificial cycle group,4 cases in which the transplantation was cancelled,including 2 cases who were cancelled due to breakthrough bleeding and 2 cases due to endometrial thickness that were less than 7 mm.There was a statistically significant difference in the cancellation rate between the two groups (x2 =4.13,P =0.04).There were no statistically significant difference in embryo frozen storage time,retrieved oocytes in fresh embryo cycle,frozen thawed embryos in the survival rate,graftage embryonic number,high-quality embryonic rate,endometrium thickness in conversion day (P > 0.05).Estrogen level,luteinizing hormone (LH) levels on endometrium conversion day in GnRH-a down regulation plus artificial cycle group and artificial cycle group were respectively as [(1 439.38 ± 357.43) nmoL/ml vs (1 580.54 ± 479.69) nmol/ml and (2.32 ± 0.94) mIU/ml vs (9.46 ±1.52) mIU/ml],with statistically significant difference (x2 =53.64,P < 0.001;x2 =14.32,P < 0.001).(3) The biochemical pregnancy rates of the patients in the GnRH-a down regulation plus artificial cycle group and artificial cycle group were 72.73% and 53.23% respectively,with statistically significant difference (x2 =5.23,P =0.036).The clinical pregnancy rate (65.15%) in GnRH-a down regulation plus artificial cycle group was higher than that of the artificial cycle group (46.77%),with statistically significant difference (x2 =4.39,P =0.022).There was no statistically significant difference in early abortion rate and ectopic pregnancy rate between the two groups.Conclusions In frozen embryo transplantation cycle,long-term GnRH-a down regulation after artificial cycle scheme is superior to simple artificial cycle scheme with significantly reduced cycle cancellation rate,low estrogen and LH levels in endometrium transformation day and higher biochemical pregnancy rate and clinical pregnancy rate.
