Contraception for men? Scientists create a new gel that reduces the amount of semen

A viable contraceptive option for men – with the exception of condoms – is one step closer to becoming a reality, because this week National Health Institutes (NIH) announced their plans for clinical research.

The trial will test the effectiveness of the Progestion Gel developed by the Population Council and the Euclidean Kennedy Shriver National Childrens Health and Human Development Institute.

"Many women can not use hormonal contraceptives, and male contraceptives are limited to vasectomies and condoms," said Diana Blithe, Director of the National Contraceptive Program for Children's Health and Human Development. "A safe, highly effective and reversible male contraceptive method would meet an important public health need."

The gel is blurred on the back and shoulders of a man and effectively stops sperm production by combining two different hormones. In other parts of the body, hormones replace testosterone.

The statement on the gel says:

"Progestin blocks the production of natural testosterone in tests, reducing the production of semen to a low or non-existent level. Replacing testosterone retains sexual desire and other functions that are dependent on adequate hormone levels in the blood."

Blit explained to BloombergQuint: "You stop [la testosterona] at the exit, but you replace it in all other areas that keep everything that works normally. "

The researchers plan to register 420 pairs. Men will be given a gel and will control their sperm level as well as possible side effects. After four to 16 weeks, when the sperm level drops properly, they will check if the gel is actually effective in preventing pregnancy.

"The potential of this new jelly is huge," said Dr. William Bremner, MD at Washington University School of Medicine, who is helping test new contraceptive methods, NBC News said. "It is badly believed that men are not interested or even fearful of tools to control their fertility. We know that this is not the case."
