First, always consult your physician before changing the quantity or type of any medicine like this, especially an SSRI. I have OCD as well, and I can tell you that it can be a debilitating disease.
What I would recommend is a full blood test that includes all the things people talk about on here-- free testosterone, luteinizing hormone, etc. There is a link between OCD and free testosterone, but it is complicated. Basically, it starts with gonadotropin-releasing hormone which gets kicked off in the pituitary gland and is transported to the testes and adrenal gland where it stimulates the synthesis and release of certain androgens of which testosterone is one. These androgens are then transported to certain organs in the body the most important of which is the brain where the androgens stimulate certain receptors.
It is here, at the receptors, where I suspect people like us who have OCD begin to see a problem. If your receptors are hypersensitive to the androgens, then this creates a sort of negative feedback loop, and your brain says "send less gonadotropin-releasing hormone"... this leads to less testosterone being released but your brain acts as if a normal or higher than normal level of testosterone is present. This is why many people with OCD have a strange mix of high androgenic qualities with low free testosterone levels.
SSRIs primarily affect a whole different set of variables in the brain that deal partly with how we respond to perceived threats (fear circuit). So, as you might expect, there is a delicate balance here that can probably easily be screwed up.
The guy who probably understands OCD better than anyone else is Jeffrey Schwartz at UCLA (see You Are Not Your Brain). If you want to address your OCD, I would suggest reading his books and implementing his 4 Steps Program in addition to medicines your physician may put you on. And be careful! OCD can be crippling. It is among the most intransigent diseases there is. Don't mess around.
