Recently, there have been advances in scientific research that has led to the discovery of taste receptors that are outside of the mouth. These taste receptors are scattered throughout the entire body, with large concentrations on the testicles and anus. Sweet and Umami taste receptors are present in this area and can present a minor taste sensation (though nowhere near as well as our mouths can). Through a simple lab test on rats, scientists were able to disable the taste receptors to see if it would have any major impact on them. In attempting to breed rats that did not have functioning taste receptors on the testicles, scientists discovered that the sperm was rendered deformed and unable to fertilize, making the rats infertile. The drug that researchers used to block these taste receptors was the same kind of drugs that are used to treat high cholesterol in humans. This discovery can help scientists to discover ways to treat infertility in humans, as it may be as simple as damaged taste receptors (Styles).
Another consequence of this discovery is a newer way to possibly lead to a male birth control pill. The disabling of these taste receptors lasts considerably longer than regular birth control pills in females, and unlike a vasectomy, is much easier to reverse. Along with this possible attempt at male birth control, many other processes have been made recently, as currently available methods of pregnancy prevention for males do not have high actual success rates due to misuse.
