Pill to eliminate sperm and increase orgasm? Too complicated - why not just a pill (or a water additive, etc) that vastly reduces the male sex drive? After all, since the high male sex drive is the engine of reproduction, needed in human scarcity times but quite superfluous (and often very destructive, let's face it) otherwise, turning off the engine entirely makes more sense than tinkering with it.
Then, when we have almost zero birth rate because men don't want sex, we can wait for the high number of older folks to pop off, then gradually turn up male sex drive with a reverse-treatment - of course, for only the 'best' male specimens- just enough to repopulate to a healthy number, also improving human stock.
Seriously, though, there is a male pill coming to market very soon that lowers the sperm count to almost nil, with the count returning to normal after a few months cessation - but alas, no multi-benefits, sorry. How many men will be willing to take it is an interesting question...but it certainly won't solve any of our population problems...too few men will have access. Also, many women may be hesitant to take a guy's word that he's on bc - incredibly enough.
I don't suppose men would be willing to forego sex entirely, even to save the planet...
nah, I though not.
It is probable that eventually chemicals from this bc will get in the water and soil, just like all the other chemicals have, and affect male sperm count across the board- and it is quite conceivable that governments may covertly add it to the water supplies in a desperate attempt to reduce overpopulation. Hmmm, maybe the sex drive pill won't be needed after all. Gads...
*Men should give thought to getting a vasectomy while it's still fairly cheap and available- because your sex life will probably be drastically reduced when there's a crash/huge recession/oil shortage for non-essential pharmaceuticals/whatnot and bc products become scarce or very expensive. Also, there's no sense in adding (or risking adding) another human to the planet's burden; especially in these times, and the worse ones to come.
