What causes low libido?

Hi. Many things can cause low libido, such as illness, pain during sex, drugs, alcohol, psychological factors, sexual abuse, anorexia, etc. In women, menopause and pregnancy can cause low sex drive. Antidepressants can cause low libido. However, there are certain antidepressants that don`t inhibit sexual desire. I am not sure about Viagra. I have never dared trying it. I`ve heard Viagra is responsible for at least 60 deaths. I don`t want to be 61. I am reading about herbs that may help you with low libido. Herbs sound ok.
