article imageResearchers: There is a way to block sperm

By Owen Weldon     Dec 3, 2013 in Science
Scientists have identified a way to block the transport of sperm during ejaculation, which means that there could be a new male contraceptive on the way.
According to Science Alert, Scientists discovered a way to achieve complete male infertility by blocking two proteins, which are located on the smooth muscle cells. The muscle cells is what triggers the transport of sperm.
According to GlobalPost, There have been previous attempts at developing a birth control for males. The ways including altering a man's hormones, or making his sperm ineffective.
However, those ways could cause long-term damage, according to researchers at Monash University in Australia.
According to Fox, The new study bred some mice that lacked P2X1-purinoceptors, as well as the 1A-adrenoceptors. The females were still able to reproduce as normal, and as usual the male mice mated with them, but the females never gave birth to babies.
The male mice's Vas Deferens did not contract normally, which suggested that the movement of sperm was stopped due to the lack of receptors.
Researchers said that if a new drug were to be developed, then men would need to be psychologically prepared.
