Condom-free male contraceptive test on monkeys successful
A new male contraceptive gel 'Vasalgel' has been successfully tested on monkeys. The gel injected in 16 male monkeys before breeding, produced no side effects along with no pregnancies in females. The procedure, awaiting human trials, involves injecting a hydrogel in the sperm-carrying tube, vas deferens, rather than cutting it as in vasectomy, to filter sperms from the fluid ejaculation.
