As a male I would not take any contraceptive that altered my hormonal balance. And the idea of getting a MONTHLY injection – are you crazy??? (This is probably why surveys come back saying there’s limited interest in male contraceptives – given that sort of choice, I’m not interested either!). However, a one-time injection (every 5-10 years) such as RISUG/Vasalgel that does not mess with the hormonal balance, and is reversible… what’s not to like? Sign me up, NOW please!
