Testicular volume and masculine identity in men with unilateral cryptorchidism: results of a community-based survey in Korea.
We determined the influence of cryptorchidism on testicular volume and masculine identity in young men living in a community. Of the 27,202 men aged 20 years dwelling in the community, we randomly selected a 10% sampling fraction of whom 2,080 men (a response rate of 77.0%) agreed to participate in the study. All volunteers underwent a standard evaluation, including a detailed medical history and physical examination. For the evaluation of the influence of cryptorchidism on masculine identity, we used the Bem Sex Role Inventory (BSRI). Among participants, 38 (1.8%) had cryptorchidism or a history of surgery for cryptorchidism (right 15, left 21, bilateral 2). In total, 29 had had undergone surgery (mean age at the time of operation; 8.9+/-3.9 years, range; 2-19 years). Of 25 men who had undergone orchiopexy due to unilateral cryptorchidism, the testicular volume of the affected side was significantly smaller than that of the contralateral side. Of the 36 patients with unilateral cryptorchidism, the contralateral testicular volume of men who had undergone orchiopexy was not different with that of those who had undergone orchiectomy or had not undergone surgery. When we compared the scores for masculinity and femininity using the BSRI between men with and without testis in the scrotum, there were no differences between the two groups. Our results demonstrate that delayed orchiopexy does not improve the testicular volume of the affected side or the masculine identity in men with unilateral cryptorchidism. In addition, these findings suggest that there is a need to increase the awareness of cryptorchidism among all parties involved in the health care of children.
