Abstract
BackgroundThe embryological development of the testicles and their descent to the scrotum is multifactorial process, and the role of the internal inguinal ring has not yet been clarified. In this study, we aimed to assess the role of the internal inguinal ring in this process by comparing the inguinal and abdominal orchiectomy specimens histopathologically. The patients were classified according to localization of the undescended testicle as group 1 (n = 11), consisting of abdominal-localized individuals, and group 2 (n = 40), composed of inguinal-localized individuals. Data regarding age, side of the undescended testicle, testicular volume, spermatic cord length, testosterone level, semen analysis, and histopathological reports of undescended testicles in both groups were analyzed and compared.ResultsThe median age of groups 1 and 2 was twenty-one. The median testicular volume was significantly lower in group 1 than in group 2 (p = 0.002). In addition, progressive motility and normal sperm morphology rates were substantially higher in group 2 than in group 1 (p = 0.019 vs p = 0.029). There was no difference between the groups in terms of analyses of histopathological parameters performed in testis tissue. (p > 0.05).ConclusionsAlthough testicular volume, sperm motility, and normal morphology rates were lower in abdominal testes, no significant differences were found in histopathological parameters between the groups.
Highlights
An undescended testicle, one of the most common abnormalities in newborns, is a condition in which one or both testicles are not in the usual scrotal position and are located elsewhere between the abdomen and upper scrotum

This study aims to assess the role of the inguinal canal by comparing the abdominal and inguinal testis specimens and semen parameters in adult patients of similar age groups who underwent an orchiectomy procedure with the diagnosis of an undescended testicle
Summary
One of the most common abnormalities in newborns, is a condition in which one or both testicles are not in the usual scrotal position and are located elsewhere between the abdomen and upper scrotum. During the passage through the inguinal canal, the testis may be located in the abdominal cavity or at any level of the inguinal canal as an undescended testis. If this is not corrected surgically in the early period, atrophy in the seminiferous tubules precludes spermatogenesis and histogenesis of spermatogenesis. The embryological development of the testicles and their descent to the scrotum is multifactorial process, and the role of the internal inguinal ring has not yet been clarified. We aimed to assess the role of the internal inguinal ring in this process by comparing the inguinal and abdominal orchiectomy specimens histopathologically. Side of the undescended testicle, testicular volume, spermatic cord length, testosterone level, semen analysis, and histopathological reports of undescended testicles in both groups were analyzed and compared
