Hypogonadism is a condition in which the body doesn't produce enough sex hormones. There are two main types:
Symptoms really depend on when hypogonadism develops and can include things like low sex drive, erectile dysfunction, reduced facial/body hair, depression or irritability, hot flashes, and breast growth.
To diagnose hypogonadism, doctors check hormone levels with a blood test. They may also examine the testicles or ovaries using ultrasound.
Treatment involves testosterone or estrogen replacement, usually with gels, patches, injections, or pellets placed under the skin. This helps restore normal hormone levels and relieve symptoms. Treating any underlying cause can also help in certain cases.
