A non-hormonal contraceptive method, named Vasalgel, and indicated for males, could be available in 2018, if the good results obtained so far in animal trials – rabbits and monkeys – are confirmed in humans. It is a Hydrogel polymer is injected into the vas deferens of the male – through which sperm move from the testicles to the penis – which acts as a selective filter, since it allows the passage of the fluid, but not sperm.
Vasalgel stays in place for about ten years, but if the male decides to have children before this time, only has to undergo an outpatient procedure to eliminate the contraceptive
Vasalgel, which has been developed by the non-profit Parsemus Foundation medical organization, has similar efficacy to the vasectomy – an intervention surgical that it is cut and bind the vas deferens to prevent the exit of the sperm-, which is superior to 99%, but a procedure is non-invasive and reversible, so you can recover the fertility if desired.
The gel stays in place for about ten years, but it is a reversible method, if the male decides to have children until the period during which maintains its effectiveness are met, only has to undergo another procedure of ambulatory character, which deletes the product of the vas deferens through the injection of a solution of bicarbonate of soda.
The latest study in which the drug has been tested successfully, the results have been published in the journal Basic and Clinical Andrology, has been conducted with Rhesus monkeys for more than one year and, as explained by Elaine Lissner, Director of the Parsemus Foundation, has shown good tolerance and lack of side effects long term , what if all continues according to schedule could prove it in humans in 2018, and even to reach the market in that year, if the approval of the Agency of the American drug (FDA).
