The volunteers received a 500 milligram monthly shot which is a decanoate of testosterone inside an oil seed of tea, during a period of two and a half years.

From all the participants only 1% conceived a child during the trail test, proving the contraceptive has 99% of effectiveness.

However, experts are still testing and paying extreme attention to cardiovascular, prostate or behavior problems that may come up eventually.
