Abstract
This study investigates the potential correlation between in vitro fertilization (IVF) and hearing impairment in twins compared to naturally conceived twins. Analyzing data from 2416 twin infants born between 2019 and 2021. Analyze the pregnancy conditions and complications of mothers, the birth conditions of newborns, perinatal diseases, initial hearing screening results, and subsequent follow-up conditions. Our findings reveal that the incidence of hearing impairment in IVF-conceived twins is comparable to that in naturally conceived twins. Significant differences in low birth weight, preterm birth, respiratory distress syndrome, and hyperbilirubinemia were observed between infants who passed and referred the hearing screening (P ＜ 0.05). The IVF group exhibited a lower incidence of low birth weight (P < 0.05) and older maternal age (P < 0.05), while showing higher rates of placental abnormalities and placental abruption (P < 0.05). Notably, these distinctions did not translate into a significant impact on hearing impairment. Regardless of the method of conception, the following key factors contributing to hearing impairment in twins were identified: low birth weight, preterm birth, respiratory distress syndrome, and hyperbilirubinemia. IVF technology does not exert specific effects on hearing impairment in twins, with perinatal complications being the primary influencing factors.
