Gold Nanorods Lead to Reversible Male Contraceptive

Gold Nanorods Lead to Reversible Male Contraceptive
Jun-11-13
Using injections of gold nanorods subjected to UV light, researchers have come a step closer to a non-surgical, reversible, male contraceptive.

Developed by a team in China, the technique is based upon the well-known fact that heat will kill sperm cells. The method, which has been tested on mice, involves injecting the testes with a mixture containing nanorods of gold, which would then be heated from the outside by an infrared laser. This would heat the rods up enough to kill the sperm cells, but not enough to kill the cell that make new sperm.

The method is still undergoing tests for human use, but, according team member Fei Sun, it could be used for the sterilization of domestic animals.
