High-Risk Outcomes in In Vitro Fertilization Pregnancies for Women of a Very Advanced Maternal Age: Insights from a Multi-Hospital Study in Greece.

Background

In vitro fertilization (IVF) has transformed infertility treatment, yet it is associated with increased risks of adverse perinatal outcomes, particularly in women of advanced maternal age. This study aimed to investigate the prevalence of complications such as preeclampsia (PE), gestational diabetes mellitus (GDM), preterm labor (PTL), low birth weight (LBW), and placental abnormalities (PA) among women over 50 undergoing assisted reproductive technology (ART) in Greece, where the eligibility age limit has been recently raised to 54 years.

Methods

We conducted a retrospective analysis of pregnancy outcomes in women over 50 compared to those under 50, utilizing medical records mainly from University Hospital of Ioannina but also from other public hospitals and private clinics in Greece.

Results

Our findings indicate that women over 50 face an increased risk of developing preeclampsia (PE) by 4.61 times, GDM by 1.69 times, PTL by 1.82 times, LBW by 1.67 times, and PA by 3.92 times.

Conclusions

These results underscore the need for heightened awareness and the monitoring of pregnancy complications in this demographic, informing clinical strategies to improve maternal and neonatal outcomes.
