Description
Emanuela Angelini and co-authors look at blood progesterone on the day of frozen embryo transfer, in a two thousand twenty-six paper. The women had endometriosis or adenomyosis, or neither. Both are tied to estrogen, involve inflamed tissue, and often harm fertility. It was not clear if they change hormone levels, or if more is needed for a live birth.
Records cover 1,927 women at one center, each at her first single-blastocyst transfer, from two thousand twenty to two thousand twenty-three. Care used hormone replacement or a modified natural cycle. Levels were the same across all three groups, under both kinds of care, and birth rates did not differ. One group stood out: women with adenomyosis on hormone replacement who had a live birth had higher levels than those who did not. Most women, the team says, do not need higher levels, though a subset may.
