Summary
Multiple pregnancies, often resulting from infertility treatments, show significantly higher risks for both mothers and babies. Reducing embryo transfers in assisted reproduction may improve outcomes for multiple births.
Area of Science:
- Reproductive Medicine
- Obstetrics & Gynecology
- Neonatal Medicine
Background:
- Multiple pregnancy rates have risen dramatically globally, linked to infertility treatments.
- Assisted reproduction techniques (ART) are a primary driver of increased twin and higher-order births.
- Multiple pregnancies are a significant adverse outcome in modern infertility care.
Purpose of the Study:
- To analyze the obstetric and neonatal complications associated with multiple pregnancies.
- To evaluate the risks of multiple births resulting from assisted reproduction.
- To assess the impact of multiple pregnancy on maternal and infant outcomes.
Main Methods:
- Review of epidemiological data on multiple maternity rates.
- Analysis of obstetric and neonatal outcomes in multiple pregnancies.
- Comparison of outcomes for multiple births versus singleton births.
Main Results:
- Increased incidence of maternal complications like hypertension and preterm labor.
- Higher rates of neonatal problems including low birthweight and congenital malformations.
- Significantly elevated neonatal mortality and long-term neurological impairments in multiple births compared to singletons.
Conclusions:
- Multiple pregnancies, particularly those from ART, carry substantial risks for adverse obstetric and neonatal outcomes.
- The higher risks associated with triplet and higher-order pregnancies support strategies like single embryo transfer.
- Optimizing ART protocols is crucial to mitigate the adverse effects of multiple gestations.
