Vasectomy is easiest without any future problems. So a male should get operated as female may get few post surgical problems as well as mental problems like depression.
I say if the mother is having a c-section she might as well just do it right then and there since she's cut open. But other than that idk I suppose the guy can do it
My husband will get snipped when we are done. For all we women go through, they can handle that. I know of 3 guys. It was in and out. Said it sounds worse than it is. Was a little sore but not horrible. Sez life I assume is same. With women its a surgery that takes 2-5 days to recover. Men it's a procedure that it like 30min maybe!
