How does Contragel actually kill sperm if its natural?

I’ve received lots of emails asking me how contragel works and, if its natural, how it can reliably kill spermicide.  Many people question its safety as well.

So, in this post, I’m going to do my best to answer the above questions and more, so you can understand how spermicides such as Contragel actually work.

To begin with, a spermicidal gel fulfils more than one function.  It actually does a few jobs.

First, it acts as sealant between your body and your barrier contraceptive device.  For example, if you were to hold a marker pen in your hand and squeeze it tightly between your thumb and index finger, you’d notice that, no matter how hard you squeeze, you would not be able to form a watertight seal.  The vaginal walls would be far less strong in comparison, therefore the seal formed between the walls and your diaphragm wouldn’t be complete or watertight.  So, the first function of a spermcidal gel is to act as a viscous gel that seals the gaps and acts a physical barrier.  If you were using a cervical cap, the gel would also increase its suction and hold it up agaisnt the cervix more firmly.

The second function spermicidal gel fulfills is that it acts as a barrier, viscous substance which most of the ejaculate sticks to, therefore restricting its movement.

The third function it fulfils is to actually kill the sperm. Nonoxynol 9 does this as a microbicide, physically breaking down cells in a brutal way (which is why it causes a lot of reported irritations with even occasional users). ContraGel uses the PH level of its Lactic Acid ingredient to kill the sperm. The PH is relatively extreme to the sperm and the swimmers are unable to survive in such a hostile environment.

The actual killing of the sperm takes only a short time, which is why cervical cap and diaphragm manufacturers always insist on leaving them in place for 6 to 8 hours before removing them.  These instructions are put in place to reduce the chance of contamination of the cervix with living sperm when the barrier is removed.

The reliability of Contragel is based sole on the reliability of the cervical cap or diaphragm you are using it with - if you don’t use them correctly, using ContraGel won’t eliminate all chances of conception.  This also brings up the many questions I receive asking whether Contragel can be used on its own or not.  The official answer is no and the unofficial answer is that I personally wouldn’t try it.  I feel much safer knowing that a physical barrier of silicone is shutting the door to incoming sperm.  To be honest, I don’t think I’d be able to relax and enjoy the moment if I were relying on a gel to catch all the ejaculate and block it from my cervix.

Another thing about reliability.  You should only use contragel, diaphragms, cervical caps or any other barrier system of contraception when you actually need it, you don’t need to bother with it when you don’t need it.  What do i mean by this?  Well, speaking with my gyno, who turned me onto the femcap was very enlightening.  What I kind of knew but never really put into practice was the concept of only being able to get pregnant for about one week each cycle.  Its what the natural family planning crowd in the Catholic Church use.  The main difference between their method and other, non-religious methods is that they are meant to abstain from sex during that fertile week (abstain: a word not in my vocabulary, I had to spell check it :) whereas I just pop my new Femcap.  Alright, there’s a bit more to it than that, I’ll try and blog about that later.

Hope this answers most of your questions.  If you have any more, don’t hesitate to get in contact with me and ask!

  2. Hi, I am sorry for my english, I am a Czech. I would like to ask you some questions about contragel. 1) When you use spermicidal gel with nonoxynol, you should not use soap before and after using it, what about contragel, can I use soap to wash my genitals? 2) Spermicidal gels with nonoxynol have usually some time, when they work, about 10 hours, but femcap can be put in for more hours, does contragel work for unlimited time, when it is inside? 3) Can I use some additional lubricant with contragel, specifically pure coconut oil? Thank you very much for answering my questions.

  3. Actually using soap on the genitals is not recommended period. Most sex educators and doctors will tell you it changes the Ph level of your genitals. It can cause vaginitis and other issues. I suggest you do not use soap with contragel either. As changing the Ph of your genitals can change the environment that sperm can survive. www.groovygreenorganics.com
