Analysis of the Association between In Vitro Fertilization/Assisted Conception and the Development of Retinopathy of Prematurity in Very-Low-Birth Weight Newborns.

OBJECTIVE

The objective is to study to what extent the development of retinopathy of prematurity (ROP) is associated with assisted conception (AC) and in vitro fertilization (IVF) in a tertiary referral hospital.

MATERIALS AND METHODS

This study is a retrospective observational cohort study. Very-low-birth weight (VLBW) infants with gestational age (GA) <32 weeks or birth weight <1500 g were admitted to the neonatal unit of a tertiary care hospital between January 1, 2011, and December 31, 2021. The study determined the degree of ROP developed according to the type of fertilization used for conception. Main outcome measures were ROP prevalence in pregnancies obtained after IVF/intracytoplasmic sperm injection (ICSI) in the period from January 1, 2011, to December 31, 2021, in a tertiary hospital.

RESULTS

Of the 408 infants included in the study sample, 105 (25.7%) were born following AC and 12.4% of these developed ROP. In our sample, the practice of IVF was not associated with an increase in the incidence of VLBW infants (R2 = 0.12; P = .29).

CONCLUSION

Conception achieved via AC or IVF is not significantly associated with ROP in any degree of severity.
