title: Clinical characteristics and treatment of cryptorchidism in adults: a single center experience.
abstract: OBJECTIVE
  We evaluated the clinical and therapeutic characteristics of adult cryptorchidism, which have been difficult to establish, given the small number of patients presenting to outpatient clinics.
  
  
  METHODS
  A retrospective study of 20 adult patients with cryptorchid testis was performed. We analyzed their palpation of testis, location, surgical method, marital status, number of children, histologic findings, and semen analysis.
  
  
  RESULTS
  In 17 cases with unilateral cryptorchidism, the mean age at surgery was 31.1±12.5 years. Fourteen patients had a palpable, small cryptorchid testis. The location of the testis, as verified, was inguinal in 14, prepubic in 2, and intra-abdominal in 1, respectively. We performed orchiopexy in 14 out of 15 patients who sought to have this procedure. Four among 6 married patients had children. Testis biopsy was performed in 12 patients, and all showed abnormal histologic findings. Three among 4 patients, performed semen analysis, showed abnormal findings. In three cases of bilateral cryptorchidism, the mean age at surgery was 35.7±12.5 years. All of these patients had palpated cryptorchid testes in the inguinal area and sought to have a bilateral orchiopexy. Two patients have been married but had no children. All showed abnormal findings in both testis biopsy and semen analysis. No testicular neoplasm was detected during the duration of follow-up.
  
  
  CONCLUSIONS
  Most adult patients with cryptorchidism preferred orchiopexy to orchiectomy. However, most of patients showed abnormal histology of the testis and semen analysis. Therefore, orchiopexy with regular scrotal examination may be considered a suitable treatment options for adult cryptorchidism.
