Male Birth Control Shot Found Effective (bbc.com)
An anonymous reader quotes the BBC:
A hormone injection has been shown to be a safe and effective method of contraception -- for men. U.S. researchers say the jab was almost 96% effective in tests on around 270 men who were using it, with four pregnancies among their partners. However, a relatively high number developed side effects, including acne and mood disorders... Because men constantly produce sperm, high levels of hormones are needed to reduce levels from the normal sperm count of over 15 million per milliliter to under one million/ml.
One professor pointed out that despite the side effects, "75% of the men who took part in the trial would be willing to use this method of contraception again."

and taking into account the risks (unwanted pregnancy) i'd say 96% effectiveness is really, really horrible.
Unless i'm mistaken in my interpretation of statistics, this is a complete failure. In this case, i'd like to know the chance that intercourse will lead to pregnangy, using this method (and only this method)
