Uses/Function

• "Birth control can also be achieved by causing a drop in a man's sperm count. This can be done by injecting testosterone, which at high blood levels inhibits the production of sperm. Recent advances have provided derivatives of testosterone that may be taken orally. Such male birth control pills have been shown to lower the sperm count in semen from normal values of about 100 million sperm per milliliter to less than 3 million sperm per milliliter, which is considered a very low concentration. Taken correctly, these pills are about as effective at preventing pregnancy as female birth control pills. Their long-term effects are still being studied." 1
