trans women have said progesterone improves transition results for a long time, but doctors have been very hard to convince to prescribe because “no evidence” and “it might be harmful“.
Study has been done. Turns out it helps and isn’t harmful https://amsterdamumc.org/en/spotlight/addition-of-progesterone-leads-to-increased-breast-growth-for-transgender-women.htm
I’ll have to do a full blog post when the study is published.
Addition of Progesterone Leads to Increased Breast Growth for Transgender Women | Amsterdam UMC
The addition of the hormone progesterone to gender-affirming hormone therapy leads to increased breast growth for transgender people following feminising hormone therapy. This is demonstrated by an Amsterdam UMC-led trial among 90 participants and these results are presented today at the European Professional Association for Transgender Health (EPATH) annual congress in Hamburg.
