Is infertility after surgery for cryptorchidism congenital or acquired?

We evaluated whether deletions of the DAZ (deleted in azoospermia) gene, abnormal karyotypes or hypogonadotropic hypogonadism (HH) were demonstrable in infertile men who had undergone surgery in childhood for cryptorchidism with a simultaneous testicular biopsy that demonstrated no or almost no germ cells. In six men with infertility after surgery for cryptorchidism, the adult karyotype and analyses for the DAZ gene, serum follicle-stimulating hormone, luteinizing hormone, and testosterone were performed from a peripheral blood sample. Testicular volume was also measured. All patients exhibited a 46,XY karyotype. There were no deletions of the DAZ-gene, no HH and no testicular atrophy. The infertility was thus not proved to be congenital, and consequently, surgical treatment is indicated before the germ cells disappear from undescended testes. This appears to be before 15 months of age.
