A recent research that got published in the journal Reproductive Biology and Endocrinology has revealed that a group of scientists from North Carolina University has been developing a novel contraception for men.

They have tested their research on rats and have found that a dose of ultrasound on testicles is effective enough to control the production of sperms in them. The lead researcher, James Tsuruta, said that through their research, they have found that sound waves are quite effective to reduce the sperm count to such a level which could make a human as infertile.

James further affirmed that till now their research findings seems to be fruitful, but they would need to conduct further tests to be completely assured. Giving more information about the research concept, James said that it is not their original concept. It was first being purposed in 1970s and they have purchased it.

The Bill & Melinda Gates Foundation has funded their research in which they have found that two doses of 15 minutes of each is effective enough to decrease the sperm count to such a level, which could make a man infertile.

In their test, they found that after two doses rats dropped 10 million sperm per milliliter. It is good news that now they are a step closer to develop an entirely new contraceptive for men.

Allan Pacey, who is a professor in andrology at University of Sheffield said, "It's a nice idea, but a lot more work is needed". He said that it was likely that there would be recovery of sperm production, but the "sperm might be damaged and any baby might be damaged" when sperm production resumed".

James said that once they are done with their research then they would be able to tell about it public. But for now they need to conduct some more tests which could tell them more about their development.
