Description
Batuhan Turgay and colleagues compare in 2026 two start times for hormone support in frozen embryo transfer using a natural cycle. Support with progesterone began either two days before transfer or on transfer day itself, and pregnancy outcomes were compared.
The review covered 246 transfer cycles from 2022 to 2024 at one university centre. Blood progesterone on transfer day was higher when support started earlier, yet pregnancy and live birth rates were higher when support started on transfer day. Adjusted analysis kept that link. The counterintuitive pattern invites caution, since treatment choice was not random and centre routines may explain part of the gap.
