Injectable male contraceptive 100% effective, say scientists

THE first injectable male contraceptive could be on the way after a trial in Australia proved 100% effective.

In the study, 55 men received hormone treatment over the course of a year containing a combination of the male hormone testosterone and progestin, which is used in female contraceptive pills, in an attempt to “switch off” sperm production.

None of the men showed any side effects and none of their partners became pregnant, scientists from the Anzac Research Institute in Sydney said.
