The addition of the hormone progesterone to gender-affirming hormone therapy leads to increased breast growth for transgender people following feminising hormone therapy.

Our results show that progesterone is safe and effective for transgender people. We’re now able to prescribe it, in a trial setting, for those who have been taking oestradiol for at least year. We hope that our findings lead to better hormone treatments for transgender individuals." Koen Dreijerink, endocrinologist at Amsterdam UMC

    The largest increase was seen in the group who also increased their oestradiol dosage with some frequent side effects such as short-lasting tiredness, breast and nipple sensitivity and mood swings.

    would be nice to actually read about the trial … should be stated, this isn’t published yet, hasn’t been peer reviewed, and doesn’t constitute a strong body of evidence (yet)

    but it makes sense that the consistent anecdotal experience of many trans women that progesterone increases breast growth might eventually be demonstrated empirically 😅
