Objective To assess the clinical features found in infertile men in whom the histological diagnosis of Sertoli-cell-only (SCO) was made on testicular biopsy. Patients and methods A retrospective review was carried out of the seminal fluid analysis, testis size and follicle-stimulating hormone (PSR) levels of 72 men who had bilateral testicular biopsies due to infertility when one (30) or both (42) of bilateral testicular biopsies showed tubules containing only Sertoli cells. Ln a subgroup of 15 men, the biopsies were re-examined to correlate the morphological features with the plasma FSH level. Results When both biopsies showed bilateral SCO the patient bad azoospermia (86%) or oligozoospermia (14%): the testicular size was normal in 36% and the FSH level was normal (43%), raised (21%) or grossly elevated (more than twice normal, 36%), When one biopsy showed SCO, the opposite testis showed appearances which varied from grossly impaired spermatogenesis to almost normal spermatogenesis. The clinical findings were also very variable. Conclusions The clinical features associated with the histological diagnosis of SCO are extremely variable, Biopsy evidence of bilateral SCO cannot be relied upon to indicate a total absence of spermatogenesis in the testes.

Abstract

Objective To assess the clinical features found in infertile men in whom the histological diagnosis of Sertoli-cell-only (SCO) was made on testicular biopsy. Patients and methods A retrospective review was carried out of the seminal fluid analysis, testis size and follicle-stimulating hormone (PSR) levels of 72 men who had bilateral testicular biopsies due to infertility when one (30) or both (42) of bilateral testicular biopsies showed tubules containing only Sertoli cells. Ln a subgroup of 15 men, the biopsies were re-examined to correlate the morphological features with the plasma FSH level. Results When both biopsies showed bilateral SCO the patient bad azoospermia (86%) or oligozoospermia (14%): the testicular size was normal in 36% and the FSH level was normal (43%), raised (21%) or grossly elevated (more than twice normal, 36%), When one biopsy showed SCO, the opposite testis showed appearances which varied from grossly impaired spermatogenesis to almost normal spermatogenesis. The clinical findings were also very variable. Conclusions The clinical features associated with the histological diagnosis of SCO are extremely variable, Biopsy evidence of bilateral SCO cannot be relied upon to indicate a total absence of spermatogenesis in the testes.
