Hi DonCarlos,
I have no idea why you wish your libido to go away, I would give anything to have mine back but of course I don’t know your circumstances so it’s unfair if me to judge.
What I would say though that it is a drastic thing to do as the long term effects might make you regret your decision. I’ve been without Testosterone for 2.5 years and suffered a significant change in my physical and mental health, and I wouldn’t wish it on my worst enemy.
I suspect you would have to have it done privately and even then I’m not sure if they would agree to it.
If you’re worried about PCa, get yourself regular PSA tests so that if you do get PCa there are many options available to you.
