Story summary

A Chinese trial finds timing frozen-embryo implantation to natural ovulation yields live birth rates similar to standard IVF with fewer complications.
The study involved 4,400 women and showed 42% live births in the natural group versus 41% in the programmed group.
The natural approach also reduced pre-eclampsia risk to 2.9% from 4.6%.
Dr. Anne Steiner said both methods work, and U.S. trials could confirm natural timing and influence IVF practices.
