Doctor's View on Low Testosterone (Low-T) Symptoms

Comment by Melissa Conrad Stöppler, MD

Testosterone is a natural male hormone produced by the testes in men. It is also present in small amounts in women and is made by the ovaries. Low T refers to having too low levels of testosterone. This condition has been described in both men and women. Low testosterone levels can be caused by problems with the glands (testes and ovaries) themselves or problems with the pituitary gland and hypothalamus of the brain. Aging is also a known cause in men, and obesity can also lower testosterone levels.

Low-T symptoms in men

Various symptoms have been described in men with low T. These can include sexual symptoms like erectile dysfunction (ED), decreased sex drive, and infertility. Men with low T can also show a decrease in muscle mass, hair loss, and osteoporosis (decreased bone density). If low T occurs prior to puberty, sexual maturation can be impaired.
