“Vasectomy essentially ensures that in most cases the patient will be sterile after confirmation of success following surgery. The procedure is regarded by the medical profession as permanent because vasectomy reversal is costly and often does not restore the sperm count and/or motility to pre-vasectomy levels.”
If vasectomy surgery was the answer then most of us would have had one, vasectomies don’t much appeal to men, especially 17 and 19 and 20 year old men, or hardly any man who isn’t married or old, getting fixed is not exactly top of the list for college kids.
An easy dependable form will be invented for men someday, and when it is, then men will temporarily control the world of sex, 100%, no lawyers, no government, no coerced marriages, no aborted children, all control will be in the hands of the man and their barely controllable sex drives.
My prediction is that women won’t accept that power imbalance for long, for then, they would truly be nothing but play things with no gains in return.
I’ve heard, not recommending it, but heard, that a hot bath will temporarily kill sperm. There’s a reason that testicles dangle, getting looser in hotter climes and pulling up close in colder ones; adjustment of the temperature is needed to ensure that the family jewels keep on optimally doing what the good Lord set them in place to do. However I really believe it an abomination to purposely misuse one’s sexual faculties. When the bible says to keep the marriage bed undefiled, this isn’t just a nice sentiment. From this point of view, anything that is meant to pervert the God given purpose of the sex act between two spouses is a bad thing. Not the unforgivable sin, it won’t scuttle a salvation you have accepted, but you don’t keep doing it unrepentantly if you want to be blessed and want to avoid divine chastisement.
