Just to mention it, although it seems like you already know, doing blockers only for an extended period of time is very bad for your health in numerous ways, you need at least a bit of one sex hormone or the other to continue living normally. Some would even say you need a tiny bit of both, as a complete deficiency of either testosterones or estrogens, even if you have a lot of the other, can lead to some undesirable effects, depression, loss of libido, etc. Both men and women produce both hormones, it's just the amount that differs this amount of estrogen in a male is enough for their health while they have T, but generally not enough to prevent bone loss and all that other good stuff from low sex hormones while on blockers.
