If even a small percentage of sexually active men agreed to try a new method of birth control, that would amount to a colossal number of potential consumers. That's why Thompson doesn't believe the drug industry's hesitance to develop male hormonal birth control is merely about money. "The biggest hurdle that I've encountered in trying to share this information is a sort of knee-jerk reaction that men aren't interested in these kinds of contraceptives and that women won't trust them to take them," she says. "Neither of those assertions are supported by the data."

Indeed, many men say they are open to trying new forms of birth control. In a 2005 global survey conducted by Schering of 9,000 men ages 18 to 50, 55% expressed an interest in a "new male fertility control," and roughly 40% of the American respondents who said they would be interested in new male contraceptives further said they would be willing to use an implant or receive regular injections to control their fertility.

Any man that would take a pill to stop sperm production should have his balls stripped off and be immediately classified as a full-blown eunuch (or gay). No sane woman wants a man who would take a male pill.
