leuprorelin is a very powerful castration drug, it will literally kill your libido, n totally prevent the ability to get erect, it's so powerful because it's a puberty blocker too, it works by shutting down the LH, FSH and pituitary GnRH receptors, it even blocks estradiol in males, I personally wouldn't go near the stuff, I use bicalutamide n dutasteride, because it doesn't mess with all that stuff, it just blocks the effects of testosterone on my body.
Testosterone really shouldn't be completely annihilated, just put into female range, because testosterone deficiency can cause problems.
If an anti androgen like, cyproterone, bicalutamide and flutamide is taken with an LH, FSH agonist they will have the same effect as leuprorelin, triptorelin and goserelin, they will cause full chemical castration n totally annihilate testosterone at the source, they use to use these drugs to forcefully castrate transsexuals as a requirement of transitioning, for an example this requirement was only lifted in Sweden in 2013 they also had to have srs and have all banked sperm destroyed, just to get female on I.D or birth certificates before 2013 and other countries have been little better, so be carefully many doctors are still in favor of this method, the exact same method that labeled a transsexuals gender dysphoria as a illness/disorder and sexual deviancy, just like they labeled homosexuality and I don't know how much you know about this, but homosexuality use to be illegal, but they allowed for people to become transsexual despite this, meaning total castration of them/us, plus pre-op transsexual marriage was n still is illegal in most places, unless you have no kids n have had srs, like seriously there has been very little change n it only all started to change not so long ago, it's all political crap.
This should probably be in a different thread...
history of discrimination, I should put that thread in, I looked into a lot of it before I started HRT.
