The evaluation of sexual function after hypospadias is mainly in the areas of libido, quality of sexual life, ejaculation, and fertility. In terms of sexual desire, most of the literature reports no significant difference between preoperative and postoperative periods, while some literature reports a decrease in sexual desire in 10% of patients after surgery. Regarding the quality of sexual life, some scholars compared the postoperative period after hypospadias with that after circumcision, and there was no significant difference, but if there were complications from the surgery at that time, the impact on sexual function was significantly increased. The main effects on sexual function are dissatisfaction with appearance, penile recurvature, painful erection, and erectile dysfunction, with the proximal type (penile root type, scrotal type, and perineal type) being more affected than the distal type (coronal groove type, penile body type). Postoperative ejaculatory disorders are factors that affect the patient’s sexual and reproductive function, and potential causes may be: immature prostate, seminal vesicle obstruction, urethral diverticulum, etc. In terms of reproductive function, relatively few cases have been reported. Therefore, successful surgery is the basis for a happy life, and professional follow-up, evaluation, and comprehensive treatment is the guarantee.
