What is hypogonadism?
Hypogonadism can occur when a person’s sex glands (gonads) don’t produce enough, or any, hormones. It can cause a lowered sex drive (libido), altered sexual characteristics, infertility, and other health conditions.
Hypogonadism can affect both male and female adults and teenagers.
There are two types of hypogonadism: primary, caused by insufficient sex hormones, and secondary, usually caused by the brain or pituitary gland. Both types can also be caused by an inherited trait, or from an injury or infection.
When does hypogonadism begin?
It can start before birth when the fetus is developing, before puberty, or in adulthood, including after an injury or infection.
