According to, Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Low testosterone can cause anxiety which may lead to depression. Some men say they have no reason to be depressed yet have it anyway. 

Hair Loss

Do you notice that you are losing more hair than normal?

This is usually pubic and other body hair. If this begins to thin it may indicate low testosterone.
