Yes, an orchidectomy, which is the surgical removal of one or both testicles, can affect sexual function in individuals. The testicles are responsible for producing testosterone, the primary male sex hormone, which plays a crucial role in sexual function and libido. Therefore, the removal of one or both testicles can lead to significant hormonal changes that may affect sexual function.

Here are some ways an orchidectomy can impact sexual function:

  1. Decreased Libido: Testosterone is essential for maintaining sexual desire or libido. After an orchidectomy, testosterone levels are significantly reduced, which may lead to a decrease in sexual desire.
  2. Erectile Function: Testosterone also contributes to erectile function by enhancing blood flow to the penis. Lower testosterone levels may result in difficulty achieving and maintaining erections (erectile dysfunction).
  3. Orgasm and Ejaculation: Orchidectomy usually does not affect the ability to have orgasms, but it does impact ejaculation. With the removal of the testicles, semen production is reduced or eliminated, resulting in dry orgasms (orgasm without ejaculation).
  4. Emotional and Psychological Impact: The emotional and psychological impact of undergoing an orchidectomy can vary from person to person. Some individuals may experience changes in their body image or sexual identity, which can influence their overall sexual well-being.

For transgender women undergoing gender-affirming surgery, the effects of an orchidectomy are often intentional and part of the overall transition process to achieve a more feminine appearance and hormone balance. Many transgender women undergo hormone replacement therapy (HRT) following an orchidectomy to introduce estrogen and suppress testosterone, leading to more feminine secondary sexual characteristics.

It’s essential for individuals considering an orchidectomy, whether for medical or gender-affirming reasons, to have a comprehensive discussion with their healthcare provider, including psychologists and gender specialists, about the potential effects on sexual function and overall well-being. Communication with healthcare providers can help individuals make informed decisions and explore appropriate treatments or adjustments to maintain a satisfying and healthy sexual life.
