Testosterone is nothing but a steroid hormone that is primarily secreted in the testes in men and the ovaries of the women though a small amount of the hormone is secreted by adrenal glands. Proper Testosterone level has to be maintained in our body to enjoy a healthy sex life. It is quite natural that the aging process can result in the decrease of this testosterone content and most men in their mid thirties feel this deficiency. Women also feel a decrease in the level of testosterone in the post menopause period and in these cases they can go for natural testosterone supplements rather than taking the risk of costly surgeries and injections. Natural supplements are always preferred considering the low side effects they cause to our body.
