Q: Could you tell me what is the relation of Testosterone with sex drive. Does taking Propecia lower testosteron levels leading to lower sex drive?

A:There is a direct relation of sex drive with testosterone. But why on earth do you want to reduce your sex drive. If you try to reduce it today, you will want it back after sometime. Dont interfere with nature, nature doesnt do anything wrong. If you are concered with your sex drive, learn to handle it properly or get help from a good counsellor. The medicine for reducing sex drive are not recommended at all.
