It's basically a drug you can take via mouth that could potentially reduce your sex drive (at the cost of also reducing infant caring and food sharing).
Unlike other sex-drive killing drugs, this doesnt affect your testosterone production (as current research available shows so far), instead it messes with your oxytocin receptors which probably cuts/reduces the pathway to sex. So far it has only been tested on monkey (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2712625/
) not even chimps so it's effects could be different for humans. Beside it possibly making you less likely to share food and care for infants, it's also expensive as hell and only obtainable in laboratories. If any rich smart lizards are reading this, you should experiment on humans with this drug and see the effects, sex drive is shit (although I heard that a sex-drive has been linked to a drive for other things in that case maybe experiment if this drug only kills your sex drive or kills motivation for other things)
