Abstract
Polycystic ovary syndrome (PCOS) is a common female endocrine disorder that has a detriment impact on female health. Herein, the study used a case-control analysis to sought to explore the association of rs13405728, rs12478601, and rs2479106 single nucleotide polymorphisms (SNPs) with in vitro fertilization and embryo transfer (IVF-ET) efficacy in treating PCOS. A total of 163 PCOS patients (52 cycles) were selected as the PCOS group and 171 patients with tubal factor infertility without PCOS (68 cycles) were selected as the control group. Polymerase chain reaction was used to amplify genome DNA and direct sequencing to detect SNPs. The LHCGR rs13405728, THADA rs12478601, and DENND1A rs2479106 genotypes were subsequently tested. Logistic regression analysis was conducted to analyze the risk factors influencing the occurrence of PCOS as well as those influencing the efficacy of IVF-ET. rs13405728, rs12478601, and family history of DM were influencing factors for the occurrence of PCOS. The rate of abortion and number of oocytes retrieved of patients with the THADA rs12478601 CC genotype increased but the rate of clinical gestation decreased. Patients with AG + GG genotype of the DENND1A rs2479106 had increased number of oocytes retrieved, rate of abortion and incidence of gestational DM. rs13405728, rs12478601, serum E(2) value as well as fertility rate were influencing factors for efficacy of IVF-ET. It was suggested that the TT genotype of LHCGR rs13405728, CC genotype of THADA rs12478601 and AG + GG genotype of DENND1A rs2479106 had poor outcomes of IVF-ET in treating PCOS.
