Four patients with blind end of vas and vessels proximal to the internal inquinal ring were planned for orchiectomy or simple or staged orchidopexy depending on clinical situations.
For biosex males, there’s really only condoms and vasectomies, where a surgeon shuts the vas deferens tubes that let sperm travel up and out from the testicles.
But the procedure is largely irreversible: it involves stopping the flow of sperm from the testes by cutting conduits known as the vas deferens and sealing them or tying them off.
So there are tiny blood vessels, called the vasa vasorum, which means vessels of the vessels that creep along the tunica externa to bring nutrients to specifically that layer of the blood vessel wall.
So they have this ability to inject this gel into what's called the vas deferens, and it makes this plug, so then essentially it does the same thing, but you're not cutting it.
