Some searches on Google for 'Effects of a single ethanol injection into the vas deferens' reveal some very interesting articles.

Please don't try this at home.

Is this something anyone has any knowledge of?

The articles are about rats!?

Don't get upset. Jcat is talking about concept, not species. *ugh*

Some of us here are actually into the reality of castration ya know...

medical science use lab rats quite a lot before humans to test stuff on. The concept here is a single injection into the vas defrens that effectively castrates. The Archive has a lot of knowledge and I am keen to understand more about this method. It is quite easy to get hold of the vas deferens and I supect not too difficult to inject into as opposed to injections into the testes, which can take 30-40 injections for effective castration.

If it were safe to do so it would be a whole lot easier to take one shot!

The results of the injections on rats seems to be focused on producing sterility rather than castration, two very different things. --FLO--

Well, how can you be sure, you´re injecting into the vas deferens? You´d have to hit a small spot instead of a (more or less) larger organ. And the result would be a closed vas deferens, not an atrophied testicle. Infertility instead of castration. The difference is explained somewhere on the board.

That sums it up. Sterility instead of castration, androgen inhibition instead of annihilation. I think it was the testicular necrosis which led me to believe that this could mean castration in some cases.

I don't think it would be difficult to hit the spot with a needle.

It is a question of whether there is further research that determines whether the right substance injected into the vas deferens castrates. It seems to be ambiguous.

Would it be possible to disable the hormone production of the testicles without having them removed?

Like from a single injection?

There was discussion on this board about "improvac", if I remember correctly, being used to prevent "boar taint". Do not know, if it would work on humans.

Long term chemical castration would probably work the same way.

Yes. Improvac is an immuncastration (google this) drug. It inoculates you against your own Leydig cells so your bodies own immune system castrates you. It does work on humans, and has been studied for cancer treatment. But the big money is in agriculture and it is slowly getting approved in various countries.
