Melbourne ( Australia ) - Another step was taken towards the creation of a " male pill " that prevents the man impregnate his partner . Australian scientists have discovered a reversible stop sperm without affecting sexual performance form . Tests on mice showed that sperm could be " stored " during sex . The discovery was published in the journal " Proceedings of the National Academy of Sciences " (PNAS ) .
This is not the first attempt of a contraceptive for men . But until now , scientists say this new study , they brought side effects such as inducing infertility and affect sexual appetite or cause permanent changes in sperm production .
The team from Monash University , coordinated by Sabatino Ventura , raises the possibility of a safe , non-hormonal and reversible contraceptive. The pill works by genetically deleting two proteins ( alpha1A - adrenergic and P2X1 - purinoceptor ) , which blocks the release of sperm during intercourse .
The removal of proteins in genetically modified mice resulted in male animals that were completely sterile , but continued to mate normally.
" This may solve the biggest obstacle in finding a socially acceptable male contraceptive ," the scientists wrote .
The mice did not suffer any side effects and were subsequently able to have a normal offspring.
