So if a guy had his balls taken off, they can be put back on?
I thought anything that is cut off, you have certain amount of time to get to the hospital and have it put back on before that part dies.
So what if a guy was castrated and then five years later, he was proven innocent? How can he have his balls put back on? That body part would be long gone and already decayed of they threw it out. Or can you have someone else's balls put on you and bam you have a sex drive again.
No, you are right. Castration is irreversible, if you are talking about this kind:
Chemical castration would be reversible, where the man takes injections of Depo-Provera or some other hormonal drug to stop his sex drive.
A vasectomy, where they snip the Vas Deferens to prevent the flow of sperm into the semen,
might be reversible, but that would just sterilize the person, not reduce or eliminate his sex drive.
