Background: To investigate the predictive value of human chorionic gonadotropin(HCG) and progesterone(P) levels on pregnancy outcomes in patients receiving in vitro fertilization(IVF) due to simple fallopian tube factors. METHODS:We retrospectively analyzed the clinical data of 854 cycles from the simple fallopian tube factor IVF fresh embryo transfer.The clinical data of 854 cycles from January 2010 to December 2018 was divided into 7 groups according to the P level on HCG day.Live birth rates(LBR) and observe trends were calculated. The receiver operating characteristic(ROC) curve was established to determine the optimal cutoff value for P, which was used to further divide the data into 3 groups: Group 1 (P ≦ 1.0 ng/ml), Group 2 (1.0 ng/ml ≤ P ≤ 1.25 ng/ml), and Group 3 (P≥1.25ng/ml). We then compared the ovulation results and clinical outcomes between the 3 groups. RESULTS There were no significant differences in age, infertility years, Gonadotropin(Gn)dosage, Gn days, Luteinizing hormone(LH) level on HCG day, 2pronuclear(2PN) fertilization rate, clinical pregnancy rate(CPR), LBR, full-term birth rate, and preterm birth rate among the three groups, but body mass index (BMI)(P = 0.001), basal LH (P = 0.034), estrogen peak (P = 0.000), number of eggs obtained (P = 0.000) were significantly different. CONCLUSION The level of P level on HCG day does not affect the CPR and LBR after IVF. However, P levels between 1.0-1.25ng/ml may lead to good clinical pregnancy outcomes.
