Male contraceptive trial results in no pregnancies

SYDNEY, Australia - A practical male contraceptive could be a step closer after researchers said Tuesday that trials prevented pregnancies among 55 couples using it for 12 months.
The treatment stops sperm production by using implants of the male hormone testosterone under the skin and injections of the female hormone, progestin.
Experts said the results were a significant step forward that builds on many years of related research.
Previous studies have shown that a combination of testosterone and progestin can switch off sperm production in men. However, the latest study is the first to measure the effect on preventing pregnancy — the ultimate goal.
The U.S. government-funded trial, sponsored by Virginia-based family planning organization CONRAD, successfully and reversibly turned off sperm production in the men who took part, said Rob McLachlan, director of clinical research at Prince Henry's Institute of Medical Research in Sydney, Australia.
