I'm a guy, and I'm very interested in using the VCF as a contraceptive sometimes with certain partners.
Apothecus, the company that produce the product state the effectiveness as 96% (condoms 96%, the pill 98%). I was unable to find the study that produced this result.
I would guess that as this is a new product it's not possible to tell it's accuracy to within 2%, and therefore that it has a good chance of being as effective as condoms. (although obviously it could be a little worse as well) So looking for clarification.
My reasoning is that the sample size couldn't have been that big - I guess they would have tested maybe 1000 couples if that, not 100, 000. and so it could come out a couple of % different each time. Whereas with condoms there have been multiple studies.
There is also a figure of 70% effectiveness for this product floating round the web. Anyone know where this comes from as this would be a deal breaker obviously.
From reading wikipedia, I don't see any method you can combine with this to make it more effective apart from condoms, the pill etc which would defeat the purpose, but if you have an idea would be interested.
I am aware that this method has certain disadvantages compared to condoms.
