Description
Danping Li and co-authors published a study in 2026 on whether hormone levels on trigger day affect IVF outcomes in overweight and obese women. The hormone LH guides follicle growth, but its link to outcomes in this group was little studied. The team reviewed first treatment cycles for over one thousand women on a flexible blocking protocol. Women were split into three bands by trigger-day hormone level.
The lowest band had more large follicles, more eggs, and more high-quality embryos than the other bands. Higher levels tracked worse response and embryo quality. Yet pregnancy and live birth rates after the first transfer did not differ by band. Adjusted models agreed the level did not predict pregnancy on its own.
