# Comparison of obstetric and perinatal complications in intracytoplasmic sperm injection cycles with autologous oocytes and donated oocytes

## TL;DR

This study found no significant differences in pregnancy and birth complications between women using their own eggs and those using donated eggs for ICSI.

## Contribution

The study provides evidence that donated oocytes in ICSI do not increase obstetric or perinatal risks compared to autologous oocytes.

## Key findings

- No significant differences were found in gestational age, birth weight, or ICU admissions between the groups.
- Oocyte source was not associated with increased risks of pre-eclampsia, gestational diabetes, or other maternal complications.
- Patients with donated oocytes were significantly older but had similar pregnancy outcomes.

## Abstract

The aim of this study was to compare the obstetric and perinatal complications in women who became pregnant with autologous oocytes and those who received donated oocytes (DO) in intracytoplasmic sperm injection cycles (ICSI).

A retrospective cohort study was carried out by collecting data from medical records between 2019 and 2022. Only patients who underwent ICSI in an induced cycle using their own or freshly DO, with male infertility factor and tubal factor, were included.

A total of 120 patients were assessed, comprising 51 cases utilizing their own oocytes (control group) and 69 cases employing DO (study group). Patients receiving DO (n=69) exhibited a significantly higher mean age compared to those utilizing their own oocytes (n=51) (41.96±2.16 vs 38.54±1.42 years, p<0.001). There was no significant association between the source of oocytes and gestational age at delivery (p=0.296), birth weight (p=0.836), admission to neonatal intensive care unit (ICU) (p=0.120), or maternal admission to adult ICU (p=0.767). Additionally, the origin of oocytes did not demonstrate any significant association with the risk of pre-eclampsia (p=0.357), gestational diabetes mellitus (p=0.187), premature rupture of membranes (p=0.996), uterine atony (p=0.996), placenta previa (p=0.393), oligohydramnios (p=0.393), or gestational hypertension (p=0.393)."

An increase in obstetric and perinatal complications was not observed in pregnancies with DO compared to pregnancies with autologous oocytes in women undergoing ICSI without prior comorbidities. Further studies with larger sample sizes are required to validate our findings.
