The live birth rate for single babies at maternal age 42 is 60% of pregnancies. This article details the specific statistics on fertility rates, pregnancy complications, and birth outcomes for pregnancies at 42.
Key Takeaways
- Live birth rate for singletons at 42 is 60% of pregnancies
- Women aged 42 have a 5% chance of natural conception per menstrual cycle compared to 20% at age 25
- Donor egg IVF success at maternal age 42 reaches 50-60% live birth rate per transfer
- Postpartum hemorrhage risk is 10% higher at 42 (5% rate)
- Hypertensive disorders occur in 15-20% of pregnancies at maternal age 42
Pregnancy at 42 is less common and slightly higher risk, but many women still deliver healthy babies.
