Hi there, my twin has a supplementary nipple just below her right chest. Because of that we both are reluctant to get started on anything that even remotely alters the hormones, afraid of it enlarging and thereby greater scar or complications when we do have it removed. We're avoiding diet, Propecia, Spiro... anything nowadays.

We've been naturally feminine with our build, height, and voice. Oddly the male body does grow after 21 after all. Things are changing, in our case for the worst. We noticed our wrists circumference in size (its 6" now!), height (5'4", previously we were both alternating between 5'2" - 5'3"), and we just had move up a shoe size. We're not sure if we should start panicking yet. We really want to get started on Propecia, Spiro, and Estrogen BUT we cant because of that silly supplementary nipple.

Our plan is to go to Electrology 3000 once every month October to December. Each month it will cost us $10,000 just for that. We are thinking of finding a surgeon to remove the supplementary nipple (and few moles while at it) while we are in the united states the first time around for our first Electrology 3000 session. Still its a long wait and at this rate will loose all our natural femininity by the time my twin is rid of her supplementary nipple 

So the question is this: do you think Propecia, Spiro, and Estrogen has any effects on supplementary nipples or is it safe?

Hormones can make nipples get larger and stick out more.  Whether that would affect a superfluous nipple or not I don't know.  My question, I suppose, is which would you find more disturbing and/or which would be harder to fix:  The effects of more T in your system, or a possibly larger nipple/future scar?  It sounds like it may be a good conversation to have with your doctor.

Depends. Does your twin's nipple react like a normal one? Like, getting hard, itching, that stuff. If it does, then yes it will react to the hormones. If it does not, then it will likely just sit there.

Either way, it's not going to make a huge difference. If you wanted to just start Spiro for now to stop T from doing more damage, it would be fine. Spiro alone would take SEVERAL months to do anything to your breasts or nipples, so it'd give you plenty of time.
