Male Gel Contraceptive Successfully Tested On Monkey

It is no news, that the only forms of contraceptive for men at the moment are to either use
a condom  to trap the sperm or to have a vasectomy ( To cut or seal the two tubes that carry sperm to the penis). A new contraceptive ( vasalgel) that should work the same way as vasectomy has been discovered and its test on monkeys was successful. Vasalgel blocks the sperm flow by the use of a gel.
 Researchers, though as still working on it, and hope that if a man changes his mind about the use of contraceptive, it (vasagel) should be reversible to allow him have children.
The scientists behind it hope to start the test on man to know if it will equally be success as it was in the primates. The essence of the  research is to make contraceptive readily available to men.
