How does male contraceptive injection work?

Birth control has long been for women only, but soon there will be a new form of birth control for men other than condoms and vasectomy. A new research, published in the Journal of Clinical Endocrinology & Metabolism, could revolutionize contraception. It found that an injection for men appears to be just as effective at preventing pregnancy as the birth control pill.

The contraceptive is a form of testosterone that is injected into the buttocks once a month. It works by temporarily blocking sperm production. Chinese researchers injected 1,045 healthy Chinese men aged 20 to 45 years with a 500 mg of testosterone undecanoate in oil, once a month for 24 months. All of the study participants had had at least one child and all their female partners, aged 18 and 38 years, also had normal reproductive function. They found the contraceptive was almost 99 per cent effective, with a failure rate of only 1.1 per 100 men.
