New Testosterone Injections Work as Male Contraceptive


Pregnancy is a big step in life for any couple. Until now, there have only been a few ways to prevent pregnancy and most of them are centered around the female. Now, there is a new monthly injection of testosterone that works as a contraceptive in men, allowing the responsibility of birth control to be shared among the sexes.

For years, scientists have been looking for a contraceptive to be the male equivalent to the Pill. The trials that were conducted in the 1990s found that weekly injections of testosterone reduced the sperm counts for 98 percent of the men, and the effects disappeared when the injections were stopped. However, the researchers thought that the weekly injections would be considered too unpopular and troublesome with men to be a very useful method of contraception.
