And, ladies, this has nothing to do with OUR bodies, but I was curious about male birth control. Unfortunately, there's nothing yet...
"I have to say – honest to God’s truth – we’re nowhere on it. There are no fabulous advances out there, nothing is even close. And just logistically, with female birth control, you’re suppressing an egg from coming out. If I were doing male birth control, I would have to suppress millions and millions of sperm. Logistically it’s a very tricky thing and no one is even close to male contraception, but that doesn’t mean they’re not working on it," said Minkin.
