Male Hypogonadism
Male hypogonadism is a medical term for low testosterone caused by a problem in the testes, pituitary, or hypothalamus. Symptoms overlap with low testosterone but the evaluation goes deeper to find the cause.
Symptoms
Low libido, fatigue, low muscle mass, infertility, erectile symptoms, hot flashes in some men, and lower bone density over time.
Causes and risk
Testicular disorders, pituitary problems, genetic conditions, obesity, chronic illness, and medications can all disrupt the hormone axis.
How it is evaluated
Evaluation can include testosterone testing, LH, FSH, prolactin, thyroid testing, and other labs when needed.
Treatment
Treatment depends on the cause, age, fertility goals, and risks. Addressing reversible causes is often the first step.
When to seek care
Seek care for persistent symptoms affecting sexual function, fertility, mood, or bone health.
