Now, scientists have developed a contraceptive for men to take, which can temporarily prevent sperm activity.
"Daily Mail" reported that the British scientists after a long study found that men can not afford the secrets of childbearing, & Quot; block & quot; the ability of sperm motility to produce a & quot; cell permeable peptide & quot; compound that prevents sperm tail swing after implantation of male spermatozoa.
If the sperm can not swim, this also means that there will be no chance of natural combination with the female egg.
John Howl, a professor at the University of Wolverhampton in the UK, says the contraceptive effect is very surprising because it immediately blocks sperm motility, adding spermatozoa within minutes after adding the compounds It can not be normal swimming.
