Will one still have sexual function if one testicle is removed?

Removing one testicle usually preserves sexual function. Sexual function mainly depends on the hormone secretion capacity of the remaining testicles and the integrity of the nervous system. Most patients can maintain normal erections and sexual desire after surgery, and some may require hormone replacement therapy.

In healthy men who retain one testicle, the remaining testicle can increase testosterone secretion through compensatory enlargement and maintain serum testosterone levels within the normal range. The temperature regulation function in the scrotum still exists, and sperm production is reduced but still sustainable. When the cavernous nerves and blood vessels of the penis are not damaged, erectile function is not significantly affected. There may be a temporary loss of sexual desire in the early stage after surgery, which usually recovers within 3-6 months as the body adapts.

In rare cases, if the remaining testicles are insufficient or have underlying diseases, symptoms of testosterone deficiency such as loss of sexual desire and difficulty in erection may occur. Such patients need to have their testosterone levels assessed through blood tests. If the levels are lower than normal, topical testosterone gel or injection of testosterone undecanoate may be considered. People with psychological disorders caused by surgical trauma may present with psychogenic dysfunction and need to be improved with psychological counseling.

After surgery, you should pay attention to regular testing of testosterone levels and semen quality. Maintaining moderate exercise can help promote hormone secretion. Avoid prolonged high-temperature environments such as saunas to reduce the risk of thermal damage to the remaining testicles. When persistent erectile dysfunction or significant decrease in sexual desire occurs, it is recommended to seek timely consultation with a urology department or andrology department. A balanced diet can include zinc-rich seafood and nuts to help support testicular function.
