Then there is one more question from me to the progesterone. Would using the cream cause issues with the functionality of my sex organ?

For me, it wipes my DHT out so much that I cannot perform well for a day or two. Others here have no such problem.

And is it recommended to use progesterone from the beginning or only later on?

I had some growth already when I added it. I don't think there is any harm in occasional use of progesterone cream unless you have no growth yet. If so, wait.

It is taken as orthodoxy on transgender-focused boards that starting PC too early can cause overall lower growth later on. I know of no study that proves this up or down. This orthodoxy does not seem logical to me, since girls get progesterone in their system pretty early, even before their periods begin. I think age (and resulting lack of growth hormone) is the real cause.

With that in mind I think if you were to apply one pump of PC a week, to one side, alternating sides each week, you'd get fair growth. The creams I have are 20mg per pump.
