Frequently Asked Questions
What People Are Saying About Vasalgel
I provide family planning services to young people in Southern California and would love to have more to offer the young men who come in (and their partners) much more than condoms or permanent vasectomy. I speak from the front lines that most of my clients know about condoms and are NOT using them as much as we would like.

Condoms are a nice method; however I have a 3 year old that proves they are not 100% effective…
Frank B., father of 3, age 27, Illinois
We’re newly-wed but we don’t think that we’re fit to be parents yet. I’m only 23 and I think I need to grow up a couple of years before thinking about having a baby. So, instead of wearing condoms for the coming five years or so and feeling miserable about it, I want an effective solution that I can reverse in the future because I know one day we will think of having a baby. and I do not want to put my partner at any risk by using hormonal pills. Current methods all focus on the women and all have terrible side effects (my wife cannot use IUDs) and condoms are fine until you get sick of them during intercourse and just throw them away.
