Short answer is: it depends on your genetics, on how your androgenic receptors developed and where, and
on how many androgens your adrenal glands will produce after. You might need some AA forever after
orchi, as well as you might not. You'll have to try and see (always talking with your endocrinologist).
My experience in short (but remeber, we ALL differ quite, both as genetics and as metabolism).
Before SRS when I was 16 I started having fat scalp and recessing hairline. I was put on Spiro initially,
but it didn't make miracles for me. When I started Cyproterone acetate some years later, yes it MADE
miracles: face and scalp fat almost gone, hairloss stopped and the hairline started to lower (slowly) again.
After SRS at 29 I had been taking synthetic estrogens and progestins for about 8 years, and everything
was going quite fine. When I recently changed my endo and she changed my HRT to bioidentical
estradiol only (no more progestins) I started feeling VERY bad (yeah, contrarily to both common anectodal
and clinical evidence...) and also I started losing hair again (she called that: DEFLUVIUM) even if my
T levels were still lower than the minimum female range. So she decided to put me on Avodart too, but
strangely enough, after one year I still saw no results (like taking sugar). I suspect I would need some
natural progesterone, but I have everybody against that (it's the school of thought...). So she finally
told me to add a fraction of Androcur to Avodart every other day (I can't tell the dosage) and my hair
has pretty stopped falling again...(remember, Androcur IS a progestin). From blood tests, I actually have
some DEAS, they're my adrenal glands producing it, and it definitely harms me. But I'm very stressed too,
and stress also is not good for hair health... as for progestins, always remember: those with 19 or 20
carbon atoms are the 'bad' ones, which can actually have androgenic effects! The 'good" ones, with AA
effects, have 21 carbon atoms, like the bioidentical micronized progesterone. However I repeat, we all DO
differ quite enough...
But, allow me, I can't accept your "I know" list ! It's too bad for you! I now don't know you intentions
and to what extent you plan to transition but:
-you can do very much with your aspect. HRT (then castration or full SRS) already helps to some extent,
but you could also plan FFS...
-your voice can be trained a lot, and in the worst case they can lift the pitch today with voice surgery
-your anxiety and depression may well improve or even disappear with transitioning
-you definitely won't sacrifice your orgasmic ability, neither with just orchiectomy nor with SRS, it will
simply improve and become more female !!!
-I can't comment on your social concerns, all will depend on what you plan to do to your body and how...
