6 GIFs Show How Vasalgel Reversible Male Contraceptive Works
Learn about a new vasectomy-like procedure that doesn’t require ‘getting the snip.’
Male birth control options are limited. That’s one major reason why there’s been such excitement about Vasalgel, a long-acting and nonhormonal contraceptive for men that has shown promising results in animal trials. Studies reveal the gel injection works safely and effectively in both monkeys and rabbits, and that sperm flow was successfully restored in the rabbit group.
The Parsemus Foundation, which developed Vasalgel, is now dedicating its efforts to bringing the male contraceptive to clinical trials. While it is not yet clear when they will begin, the foundation says it will likely first test Vasalgel on men who no longer want children since a reversibility study in humans has not yet been completed.
For a visual explanation of how the male contraceptive Vasalgel works, check out the animated GIFS below.
1. Access vas deferens
2. Inject Vasalgel
3. Semi-permeable barrier forms
The Parsemus Foundation says that once in place the Vasalgel can remain effective for several years. Also, the procedure does not interfere with orgasm and still allows the ejaculation of seminal fluid—it will just not contain any sperm.
4. Dissolve barrier with injectable solution
To re-open the vas deferens and restore sperm flow, a solution is injected to dissolve the Vasalgel barrier. In the rabbit study, the gel was flushed out by injecting a solution of sodium bicarbonate (baking soda).
5. Sperm flow returns
