Researchers have taken another small step forward in the development of a male birth control pill. Their study demonstrated that the pill in question reduced testosterone levels to “castrate levels.” Yes, this is an awful description if they ever hope to commercialize the drug but it’s important because testosterone contributes to the production of sperm. But low testosterone would also have consequences, right? Well, the study drug contains chemicals that trick the body into thinking it has normal levels of testosterone. TBD on whether sperm count is actually affected. Also, 9 of the 83 study participants experienced decreased libido, which could let some air out of the balloon (giggle, giggle). But the study’s findings are promising enough to take it to the next stage with more participants and a look at longer-term consequences. Here is Putin making balloon animals. Why not?
