Who’s in charge of preventing pregnancy?

For years, available contraception methods have generally made this a woman’s responsibility.

But researchers report they may be getting closer to changing the calculation, according to findings published last week in the Journal of Clinical Endocrinology and Metabolism. They offered evidence that a new hormonal injection can stop men from producing sperm.

The approach, which involves an injection of testosterone and progestin every eight weeks, was tested on 320 men in seven countries. Mostly, it worked. But study participants also reported acne, pain, increased sex drive, mood disorders and depression.
