Underactive testes cause primary hypogonadism. That’s because they don’t manufacture sufficient levels of T for optimal growth and health. This underactivity can be caused by an inherited trait. It can also be acquired by accident or illness.
Secondary hypogonadism is caused by damage to the pituitary gland or hypothalamus. These parts of the brain control hormone production by the testes.
You may be affected by primary, secondary, or a mixed hypogonadism. Mixed hypogonadism is more common with increased age.
