An Effective Male Birth Control Pill Closer to Reality
According to researchers at the Monash University in Parkville, Australia, male birth control shows promise in mice.
In the trials, mouse sperm was blocked from semen while still allowing for normal sexual activity. Without sperm in the ejaculated semen, there is no chance of fertilizing an egg and achieving pregnancy. The researchers knocked out two key proteins in mice - alpha-1A adrenoceptor and P2X1-purinoceptor - transport sperm through the urethra when a man ejaculates, or releases semen.
It was found that these "double knockout" male mice were able to have intercourse, but there were no pregnancies despite ejaculation. According to the researchers, animal studies also don't necessarily translate to humans and is not ready for prime time as of now. Women shouldn't plan to abandon their birth control pills just yet.
Previously, the studies attempted to develop a male birth control pill have focused on shutting down sperm production. This approach is first of its kind because it is non-hormonal and does not affect the development of sperm.
