When mice were administered daily injections of two different doses of JQ1 over a three- or six-week period, they saw at least a 90 per cent decrease in sperm count and at least a 75 per cent decrease in sperm cell motility. The decrease in the sperm count was so substantial at the higher dose that all of the mice became infertile. Importantly, though, within a month or two of stopping the drug treatment, mouse fertility was completely restored.
Well this is AWESOME!
