What is hypogonadism?
Also known as: male hypogonadism, idiopathic hypogonadotropic hypogonadism, testosterone deficiency, primary hypogonadism, secondary hypogonadism
The testicles function as part of a brain/gonad (testis in boys) system that stimulates the testes to secrete the male sex hormone called testosterone. Hypogonadism occurs when any part of this system doesn't function appropriately.
- Primary hypogonadism is where the testes don't work properly.
- Secondary hypogonadism is where the problem originates in the brain (pituitary/ hypothalamus).
Hypogonadism may occur during intrauterine fetal life, in prepubertal boys, and after puberty.
