Penile and genital surgery for congenital or acquired conditions is daily practice in reconstructive urology. These procedures, which carry the risk of disrupting nerves and blood vessels, may impair the genital sensation, and affect the capacity for sexual pleasure. Self-reported tools are needed to systematically assess the male genitalia before and after reconstructive surgeries in terms of genital sensation and sexual experience. This study validated the Dutch translation of the "self-assessment of genital anatomy and sexual functioning in male" (SAGASF-M) questionnaire and investigated the perceptions of healthy men regarding their genital anatomy and sensory function. Eight hundred and eight sexually active men with a median age of 39 years (18-79 years) and no history of genital procedures other than circumcision filled out an online version of the questionnaire. Twenty-four participants were randomly recruited to confirm the responses of the "self-assessment of genital anatomy and sexual functioning in male" questionnaire by a clinical evaluation. The "self-assessment of genital anatomy and sexual functioning in male" questionnaire comprises of multiple-choice questions and clarifying illustrations asking men to rate their genital appearance, overall sexual sensitivity, and pain perception as well as the intensity and the effort to reach orgasm. Prespecified regions of the glans, penile shaft, scrotum, perineum, and anus are evaluated through this questionnaire. Only slight variability in anatomical ratings was observed. Overall discrimination between different genital areas in terms of genital sensation was significant. The bottom of the glans or frenular area was rated the highest contributor to "sexual pleasure," followed by the other regions of the glans and shaft. The same distribution was found for "orgasm intensity" and "orgasm effort." The anal region was generally rated the lowest. "Discomfort/pain" was rated lower than any of the other sensory function indicators and the top of the glans and anal region were rated most likely to perceive this unpleasant sensation. Participants reported significantly more sexual pleasure and intense orgasms when stimulated by a sexual partner than self-stimulation. Homosexual and bisexual men reported a higher contribution of the perineal and anal regions in sexual pleasure and orgasm. No significant difference between circumcised and uncircumcised individuals regarding overall genital sensation could be found. The Dutch translation of the SAGASF-M questionnaire is a valuable and reliable tool for self-assessment of genital anatomy and sensation, providing a site-specific attribution of a patient's perceived sexual function. Further prospective research with this questionnaire could aid in the patient-centered improvement of genital surgery.
