Injectable male contraceptive tested successfully on monkeys
It's 2017, and male birth control methods haven't really advanced beyond the vasectomy -- a procedure that's been performed since the 1800s -- or condoms. That's what makes Vasalgel so intriguing. It's a "potentially" reversible method that uses gel to chemically incapacitate sperm as they pass through the vas deferens. It doesn't stop sperm production, and, like with a vasectomy, the swimmers are just absorbed into the body. In a recent experiment, male rhesus monkeys given the treatment didn't sire any offspring during a year-long study.
