Low Testosterone (Hypogonadism) Symptoms & Signs

Low testosterone, or male hypogonadism, is a disorder in which the testicles don’t produce enough of the male sex hormone. The testicles are the sex organs or gonads of individuals born male, and the Leydig cells are the ones responsible for producing testosterone.

At different ages, low testosterone produces varied symptoms. For an adult male at birth, testosterone levels naturally drop as they age. It covers transgender people who aren’t receiving feminizing hormone therapy, non-binary individuals, male at birth, and cisgender men. Because different studies define low testosterone differently, it’s difficult for researchers to assess this condition’s prevalence.

According to data, roughly 2% of males tend to have low testosterone. However, other studies show that more than 8% of males between 50 and 79 have low testosterone.

Several factors can cause low testosterone, which comes in two types: testicular disorder or primary hypogonadism and pituitary/hypothalamus dysfunction, also called secondary hypogonadism.

The causes of these types of male hypogonadism are also split into acquired or congenital. Acquired male hypogonadism means the condition was developed later in adulthood or childhood. Meanwhile, congenital male hypogonadism indicates that the condition exists at birth.
