title: Surgical vs. untreated cryptorchidism: effects on fertility.
abstract: Forty-four patients with history of cryptorchidism were studied: 15 untreated (group A); 14 treated by orchiopexy at age 4.5 +/- 1.4 years (group B), and 15 with unilateral orchiectomy of undescended testis at 8.4 +/- 1.6 years (group C). Testicular volume, semen analysis, and LH and FSH were measured. Normal sperm counts were noted in 53%, 36% and 47% of patients in groups A, B and C, respectively. FSH and LH serum levels showed no differences between the groups. Testicular volume of the normal descended testes showed no differences between the three groups. Positive correlation was obtained between testicular volume/sperm concentration and negative correlation between gonadotropins/sperm concentration. The remaining testicular volume and gonadotropin serum values from adults with history of chryptorchidism who underwent orchiectomy were not different from those orchiopexied treated nor with untreated patients. The percentage of men with sperm count greater than 20 millions/mL was lower in the orchiopexied men compared to A and C groups. There seems to be different etiologic factors in our patients.
