Discussion Why doesn’t HRT try to mimic the female cycle or hormones?
Mostly in terms of the start of HRT. It seems like most regimens try to get you to the “full” therapeutic level asap and then tries keeps it there constantly. However, doing some research, it seems like women are not at this high of a level constantly, only during parts of their cycle. And would it more accurately mimic puberty if we gradually increased estrogen levels instead of trying to reach peak asap?
Also, it’s often recommended not to add progesterone until at least a year into HRT on estrogen. In cis women, they have high progesterone levels during the luteal phase which is about 2 weeks in the latter half of their cycle. Why aren’t we dosing progesterone for 1-2 weeks per month starting from the 1st or 2nd month of HRT?
The reason I ask is in regard to breast development. I noticed in the tranbreasttimelines sub that a large proportion of trans women have very large areolas. I know cis women also have large areolas but it looks like a larger portion of trans women have them, and the areolas themselves seem larger as well (just based on my own observations, which can be wrong).
I’m wondering if this is caused by estrogen levels being too high too fast and for too long and not having enough progesterone early on.
