Impact of HBV Infection in Couples on In Vitro Fertilisation-Embryo Transfer Outcomes and Clinical Characteristics of Newborns: A Retrospective Study Based on 3900 Infertile Couples

Abstract

To investigate the effects of chronic HBV infection on the outcome of in vitro fertilisation-embryo transfer and clinical characteristics of newborns, as well as the factors influencing different outcomes of in vitro fertilisation-embryo transfer (IVF-ET). In this study, a total of 3900 couples undergoing IVF-ET were collected and divided into four groups according to the different HBsAg carrier status of each couple, comparing the general demographic data and clinical characteristics between the four groups, analysing the differences in IVF-ET outcomes between the groups, and using multifactorial analysis of factors influencing their IVF-ET outcomes. The results showed that no significant differences (p > 0.05) were found in IVF-ET outcomes among the four groups, but multifactorial logistic regression showed that male and female age, low literacy level of men, total number of eggs acquired, LH value and P value on HCG day may affect the success rate of different IVF-ET outcomes (embryo outcome, pregnancy outcome and perinatal outcome) to different degrees. We also analysed the clinical data of 952 newborns and there were no statistically significant differences (p > 0.05) in variables including sex distribution, length, weight, health status and Apgar score. Therefore, our study suggests that neither uniparental infection nor biparental HBV infection may affect the outcome of IVF-ET or the clinical characteristics of the newborns, but the outcome of IVF-ET is affected by different factors.
