Oral contraceptives for men. It is the mechanism of fertility. In women, it is periodic by nature. Simply put, once a month in time to give the command to the body "Umm, ovulation has already been". You do not need to swallow a lot of hormones.

You are a man, right? In any case, you have hardly seen hormone pills. They are even in a package of 21 pieces - for each day of the cycle. And not one – on " once a month". The scheme is a bit different. The pills are taken constantly and they are constantly telling the body: Not today. Not today. Not today. And so every day.
