“Your normal semen contains about 40 million to 300 million sperm per milliliter, which is huge, right? And if you ask yourself, why evolutionarily does a man need that much sperm per milliliter of semen in order to impregnate women? That’s because you need that many.
A count of 10 million to 20 million greatly reduces the likelihood of pregnancy. Meanwhile, developing male birth control is akin to playing a really difficult game of Space Invaders, where you have to zap tens of millions of sperm.īut the truth is, you don’t have to get a sperm count to zero to make a person infertile.

The vitamin A signalling system plays a number of important roles in bodily systems. “If you were developing a drug that’s targeting a completely novel pathway, I think it would be appropriate to be cautious about safety when there isn’t a track record in that field.” While Noman and his team didn’t observe any side effects in mice, this doesn’t guarantee that the drug will be safe in humans, says Richard Anderson at the University of Edinburgh, UK. Noman and his colleagues have now licensed their drug to a private company, YourChoice Therapeutics, which is aiming to carry out human trials in the US later this year.
