Early Luteal Phase Progesterone Kinetics After hCG-Induced Ovulation in Modified Natural Cycle
This pilot study evaluates how progesterone levels change after hCG-triggered ovulation in modified natural cycles. Forty women preparing for frozen embryo transfer will have blood tests over 6 days to monitor hormone levels. The goal is to understand whether hCG affects the timing of the luteal phase and embryo implantation.
