EDIT: it does have a warning for male use only so in the mtf area it might be a bad Idea. Do the research, ask your doc, and I hope you get a badass head of hair.
Nah, if anything Finasteride is better for transfems than for cis men: A lot of the potential negative side-effects become potential pleasant surprises for us; some of the concerns regarding depression remain, but generally speaking it’s a relatively safe bet for people who don’t want to take T-blockers (yet).
That said: Proper T-blockers are the much more comprehensive solution and usually make Finasteride superfluous, so the primary argument against it in our case is honestly, that it tends to be a better choice to go all the way from the beginning. Even for people who can’t get a prescription, DIY (→ /c/diyhrt) is usually still the better decision.
I had a professor who in the last lecture gave us the list of all the questions he had (something like 170) and from which he would pick some subset.
He had genuinely managed to ask about pretty much everything in the course, so this really was more of a check-list of knowledge that we were supposed to have. As such it was really nice!
