Low testosterone (low-T) can be caused by conditions such as type 2 diabetes, obesity, liver or kidney disease, hormonal disorders, certain infections, and hypogonadism. Signs and symptoms that a person may have low-T include insomnia, increased body fat, weight gain, reduced muscle, infertility, decreased sex drive, depression, and worsening of congestive heart failure or sleep apnea.
Low-T can be treated with testosterone therapy in the form of gels, injections, pellets, or skin patches. Side effects of testosterone treatment include acne, anxiety, hair loss, headache and change in sex drive (libido).Read more: Low Testosterone (Low T) Article
