They also told me that although most Dutch professionals administering HRT swear against it
And yet...this Dutch study
Am J Surg Pathol. 2000 Jan;24(1):74-80.
Short-term and long-term histologic effects of castration and
estrogen treatment on breast tissue of 14 male-to-female transsexuals
in comparison with two chemically castrated men.

"(...) Hence, combined
progestative antiandrogens and estrogens are
necessary for genetically male breast tissue to mimic the natural
histology of the female breast."
"(...)Hence, Orentreich and Durr9 appropriately concluded from their
theoretical studies that estrogen alone or combined with orchidectomy
may not always induce acinar formation in the male mammary gland.
These authors thought that it could not be determined whether
estrogen, orchidectomy, and progesterone together always produce
lobules and acini, but they inferred that some castrated male-to-
female transsexuals who had received estrogens and progestins for prolonged
periods have breast tissue that histologically simulates
that of the female, that is, with acinar and lobular formation.
9 Our study now shows their hypothesis in general to be correct, but
it does not take an orchidectomy for the acinar and lobular formation
to occur, and moreover, such formation seems to decrease when
progestative antiandrogen treatment is stopped after surgical
castration.
Our findings in patient F indicate that prolonged and
regular intake of proper doses of progestins and estrogens
is needed for the full development and maintenance
of the female histology."
"(...)progestative drugs are known to stimulate
the formation of acini and lobules in females.7 "
The studies on progesterone's contribution to breast structure and formation are plenty! I have at least a dozen, I think. And there's much much more. It's also clear that through its metabolite allopregnanolone, it exerts a positive effect on mood, reducing anxiety and acting like an anti-depressant BUT some girls also report depression from it, increased tiredness...sooo, perhaps it's more anxiety reducing while estrogen is more anti-depressive, giving one energy and motivation.
Quote from: teegit doesn't take any time to google female puberty hormone levels and see that progesterone starts to become present during puberty as does noticeable breast development. Do the two coincide? My guess is yes.
I'm actually not so sure about this one. Breast development starts around the time estrogen rises in girls. But progesterone only enters the equation later, perhaps when breast development is mostly complete. Here is what one doctor says about it (and I do not entirely disagree with him as evidence seems to support his stance) although much of the other stuff he states is downright wrong!

You have to force your body to change, otherwise diet alone, HRT alone, etc., aren't going to do much of anything. Ask any trainer this.
It's quite simple really. Carbs fatten. Female HRT increases fat to muscle ratio.
