The sperm count was reduced to less than a million per millilitre in 89 percent of the men.
While different methods for contraception have been tried over the years, researchers have been tirelessly working on finding better ways. While a sperm switch that offers reversible contraception for men may be available soon, a simpler way for men to reduce sperm count may also arrive soon.
The first male contraceptive that can rubbed on the like a lotion to cut sperm count is being tested on men. The trial will be carried out by government researchers in April after a decade of research into the gel.
A six month study has already showed that the rubbing the gel on shoulders and arms everyday is effective as contraception. The sperm count was reduced to less than a million per millilitre in 89 percent of the men, and there was no sperm production in 78 percent men.
The study involved two different types of gel for different parts of the body but now researchers are combining them into one. The trial will be the largest effort to test hormonal contraception for men and will run for four years.
Currently men only have condoms or vasectomy as options when it comes to contraception. A trial testing hormonal injections for birth control was stopped in 2012 as many feared they caused depression and increased suicidal tendencies.
