Are IVF babies more likely to be born early?
Yes, IVF pregnancies have a slightly higher chance of preterm delivery compared to natural pregnancies. However, this is primarily due to factors associated with IVF rather than the procedure itself:
- Higher likelihood of multiple pregnancies (twins or triplets)
- Advanced maternal age in many IVF patients
- Underlying fertility conditions
When these risk factors are controlled for, particularly in singleton (single baby) pregnancies, the preterm birth rates for IVF pregnancies are much closer to those of natural pregnancies.
