Examining how assisted reproductive technologies affect pregnancy outcomes

Association of Assisted Reproductive Technologies Parameters With the Perinatal Outcome in Singleton and Multiple Pregnancies: A Multicenter Prospective Cohort Study

Observational Aristotle University Of Thessaloniki · NCT06918236

This study is trying to see if different assisted reproductive technologies affect the health of pregnancies and if they are linked to risks like growth problems or stillbirth.

What this trial studies

This prospective cohort study aims to investigate the relationship between various parameters of assisted reproductive technologies (ART) and perinatal outcomes in both singleton and multiple pregnancies. Researchers will assess whether ART pregnancies are linked to higher risks of conditions such as fetal growth restriction, preeclampsia, and stillbirth, while also examining potential placental and umbilical cord abnormalities. The study will adjust for confounding factors like maternal age and BMI, and will analyze outcomes based on specific ART techniques and protocols. By clarifying these associations, the study seeks to enhance clinical care and counseling for couples considering ART.

Who should consider this trial

Good fit: Ideal candidates include individuals with singleton or multiple pregnancies who have a live fetus between 11 weeks and 13 weeks of gestation.

Not a fit: Patients with known genetic anomalies or major fetal defects diagnosed before or after birth may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved clinical practices and counseling for couples undergoing assisted reproductive technologies.

How similar studies have performed: Previous studies have explored ART outcomes, but this study's comprehensive approach to examining specific ART parameters in relation to adverse outcomes is relatively novel.
