For decades, we have been begging for a male contraceptives so that women can stop pumping unnecessary hormones around their bodies.

Well UK scientists have made a breakthrough and found the secret of temporarily ‘switching off’ sperm’s ability to swim and making men infertile for a select period of time.

They have created tiny ‘designer compounds’ which penetrate the surface of each sperm and stops their tails from wiggling, and so preventing them reaching a woman’s egg, the Daily Mail reports.

The fast-acting contraceptive could be taken just minutes before sex and supposedly lasts a few days before the effects wear off completely.

The research comes from scientists at Wolverhampton University funded by a £175,000 Portuguese grant.

Lead researcher Professor John How described how effective their sperm-stopping agent had been in lab tests.

He said:

The results are startling – and almost instant. When you take healthy sperm and add our compound, within a few minutes the sperm basically cannot move.

Taking the approach of affecting sperm motility with a synthetic protein is a unique approach to male contraception

The cell-penetrating peptide will be similar to a Trojan horse in the way it smuggles itself inside sperm cells.

John Guillebaud, emeritus professor of family planning and reproductive health at University College, London, said a reversible male contraceptive would be ‘of enormous benefit to many couples, such as those where the woman cannot take the pill for medical reasons (there are many negative side effects and an increased risk of blood clots).

A German scientist invented a ‘spermatic duct valve’ to turn the flow of sperm on and off:

Live animal tests are set to start in two to three years, so the final product could be available as early as 2021.

Researchers said ‘it was too early to say’ if the end result would be a pill, nasal spray, or sub-skin implant, all of which are possible.
