Researchers often come with some innovative inventions in medical field. And this time they have found an 'On-Off switch' for Sperm movement. This will help men who suffers from 'infertility' and it is also helpful for all men. Researchers said that this is an effective form of birth control.


This can be a much better type of male birth control. Researchers at Yale University and UC Berkeley have found a switch which will turn sperm into lazy walkers when they are in testicles to vigorous runners when they are exposed to an egg.


This will definitely help some men to improve their sperm fertility. At the same time, this could also help other men to keep their sperm turned off. When sperm exposed to Progesterone, which is a hormone exerted by Ova they become energetic.


This is the hormone which is responsible for turning the switch. This is triggered by a protein named CatSper. Researchers worked on the factor which triggers the protein. They were making research on mechanism and now they have found out the solution.
