What are the chances of having twins with IVF?
The chance of twins with IVF varies but is generally higher than with natural conception :
- Natural pregnancy: About 1.2% chance of twins
- IVF pregnancy: Ranges from 6% to 25% depending on various factors
- Multiple embryo transfer: Significantly increases twin probability
- Single embryo transfer: Reduces twin risk to levels closer to natural conception
Modern practice increasingly favors single embryo transfer to minimize multiple pregnancy risks.
