Male Hormone Testosterone

Sleeping disorders, mood swings, fatigue: When it's men and not women suffering these symptoms, it can be the result of a lack of the hormone testosterone, which declines naturally with age. A medical check-up can ascertain a deficiency. Building up muscle and reducing weight stimulate testosterone production. In the case of a severe deficiency, gels or patches can help.
