I'm doing some research to educate my doctor about using progesterone for breast growth. I've got several legit references made by the medical establishment. But in general they all say that it's a wash, nothing is proven. There is just one doctor (Dr. William Powers) that does believe in it 100%, in that it can and does help fill out, round out, a transgenders breasts. But he is in the minority.
Does anyone have any others references you can provide?
Here is what I have so far;

Progesterone Is Important for Transgender Womens TherapyApplying Evidence for the Benefits of Progesterone in Ciswomen
Evidence Synthesis; It is important to add progesterone to estradiol and an antiandrogen in transgender womens CHT. Progesterone may add the following: (i) more rapid feminization, (ii) decreased endogenous testosterone production, (iii) optimal breast maturation to Tanner stages 4/5, (iv) increased bone formation, (v) improved sleep and vasomotor symptom control, and (vi) cardiovascular health benefits.

Conclusions: Evidence has accrued that normal progesterone (and ovulation), as well as physiological estradiol levels, is necessary during ciswomen's premenopausal menstrual cycles for current fertility and long-term health; transgender women deserve progesterone therapy and similar potential physiological benefits.

Conclusions; Our knowledge concerning the natural history and effects of different cross-sex hormone therapies on breast development in trans women is extremely sparse and based on low quality of evidence. Current evidence does not provide evidence that progestogens enhance breast development in trans women. Neither do they prove the absence of such an effect. This prevents us from drawing any firm conclusion at this moment and demonstrates the need for further research to clarify these important clinical questions.
Does anyone have any others references you can provide? Your help would be very much appreciated.
