Generally speaking, kidney transplant itself has no effect on men’s sexual function, but postoperative complications may affect the sexual function to some extent. Kidney transplantation involves transplanting kidneys from other individuals into the patient’s body, which in itself does not have much effect on the sexual function because the role of kidneys is mainly to urinate, detoxify and participate in metabolism, etc., whereas the body’s sexual function is mainly related to androgens in the body, so as long as it doesn’t affect the development of the testicles and penis and other reproductive organs, the sexual function will not be affected to a great extent in general. After kidney transplantation, patients will have some related complications, such as immune rejection, there will be renal failure, oliguria and other clinical manifestations, and the prevention and treatment of such complications, the need for long-term application of immunosuppressants, which increases the risk of infections, tumors, to a certain extent, affecting the patient’s sexual function. The frequency and extent of sexual life after kidney transplantation specifically need to consult the attending physician.
