What autoimmune disease causes low testosterone
What autoimmune disease causes low testosterone Autoimmune diseases are conditions where the immune system mistakenly attacks the body’s own tissues, leading to a range of health issues. Some autoimmune disorders target specific organs or glands, which can significantly disrupt hormonal balance. One such impact is on testosterone levels, particularly in men. Testosterone, the primary male sex hormone, is essential for maintaining libido, muscle mass, bone density, and overall vitality. Certain autoimmune conditions can cause low testosterone (a condition known as hypogonadism), either directly damaging the testosterone-producing organs or indirectly influencing hormone regulation.
One autoimmune disease that has been linked to low testosterone levels is autoimmune hypophysitis. This rare disorder involves inflammation of the pituitary gland, a critical component of the brain responsible for secreting hormones that regulate other endocrine glands, including the testes. When the pituitary is inflamed or damaged, its capacity to produce luteinizing hormone (LH)—which stimulates testosterone production in the testes—is impaired. As a result, men with autoimmune hypophysitis may experience symptoms of testosterone deficiency such as reduced libido, fatigue, muscle weakness, and mood disturbances. Since the pituitary governs multiple hormonal pathways, the impact can be broad, affecting not only testosterone but also other hormones like growth hormone and adrenocorticotropic hormone (ACTH).
Another autoimmune condition associated with low testosterone involves autoimmune orchitis. This condition is characterized by the immune system attacking the testes themselves, leading to inflammation and potential damage to the Leydig cells, the cells responsible for testosterone synthesis. Autoimmune orchitis can cause a gradual decline in testosterone levels, resulting in symptoms similar to other forms of hypogonadism. Although less common than other causes, autoimmune orchitis is a recognized cause of secondary hypogonadism, particularly in men who have underlying autoimmune diseases or have undergone prior infections or trauma that may trigger autoimmune responses.

Systemic autoimmune diseases like systemic lupus erythematosus (SLE) can also indirectly influence testosterone levels. SLE primarily affects women, but men with SLE may experience hormonal disturbances, including low testosterone. The chronic inflammation and immune dysregulation associated with SLE can impair the hypothalamic-pituitary-gonadal (HPG) axis, leading to decreased gonadotropin-releasing hormone (GnRH) secretion, which in turn reduces LH and testosterone production. Additionally, certain medications used to treat autoimmune diseases, such as glucocorticoids, can suppress testosterone synthesis.
The management of autoimmune-induced low testosterone involves addressing the underlying autoimmune process alongside hormone replacement therapy if necessary. Immunosuppressive medications aim to reduce inflammation and prevent further tissue damage. In cases where the testes or pituitary are significantly damaged, hormone replacement therapy may be essential to restore testosterone levels and improve quality of life. Early diagnosis and treatment are crucial for preventing long-term complications such as osteoporosis, cardiovascular issues, and metabolic disturbances.
Understanding the link between autoimmune diseases and low testosterone highlights the importance of comprehensive evaluation in men presenting with symptoms of hypogonadism and a history of autoimmune conditions. Medical professionals should consider autoimmune causes when diagnosing low testosterone, as targeted treatments can significantly improve outcomes.
