Hypogonadism occurs when the body does not produce enough of the hormone testosterone.
Hormones are small molecules in the blood stream that are important for transmitting signals in the reproductive system. Testosterone is an important male hormone, mainly produced in the testicles, that plays a key role in sperm production and fertility. Low testosterone can be a cause of male infertility, and it can also cause other symptoms such as sexual dysfunction and low energy.
Abnormal testosterone levels can be identified through a blood test.
A Northwestern Medicine reproductive urologist can also perform a thorough physical examination and consider medical history to identify potential causes of hypogonadism and identify optimal treatment options.
