A minor surgical procedure ensuring a male is unable to ejaculate viable sperm and procreate.
Vasectomies are typical performed on human males and primates, unlike castration, the male retains the ability to produce viable sperm, however the male is rendered incapable of delivering the sperm to impregnate the female. I principal the procedure is reversible but without guarantee of success.
The procedure is performed as a form of contraception and family planning thus ensuring that a female having sex with a vasectomised male cannot get pregnant by him and does not heed to use other forms of contraception. Of course, this does not prevent the female from getting pregnant by other males.
Within a
Cuckoldery or F.L.R. relationship dynamic, the male is often required to have a vasectomy, freeing the female to choose a
Breeding Bull to father her children.
There are campaign groups that advocate that all males should be vasectomised, there are moves for some areas of jurisdiction to enforce
vasectomies for various reasons on the male population.
The marriage pre-nuptial agreement was
mandatory before the marriage could take place, one of the clauses insisted the
prospective husband have a Vasectomy and his orgasm did not contain
viable sperm.
