Low testosterone levels can cause many different symptoms, including low energy, inability to concentrate, memory problems, low libido, changes in sleeping pattern, weight gain and muscle loss.
Testosterone also plays an important role in mental health. Many men, suffering from low Testosterone, often experience depressive symptoms, such as low self-esteem, low energy, irritability, slow thinking, trouble concentrating, that can negatively impact their quality of life. Some evidence suggests that treating low Testosterone may help reduce these symptoms. A recent large meta-analysis study has demonstrated that Testosterone treatment appears to be effective in reducing depressive symptoms in men.
