[Dependence of serum hormones (T, FSH, LH) on morphometric testicular findings after chemo- and radiotherapy in patients with malignant testicular tumors].

Correlations which exist between morphometric parameters of remaining testicular tissue, on the one hand, and serum hormones on the other (testosterone = T, follicle-stimulating hormone = FSH, luteinising hormone = LH), depending on therapeutic action taken on patients for malignant testicular tumours, seem to suggest that decline in epithelial thickness together with increase in wall thickness leads to rise in FSH. No unambiguous relations, on the other hand, were found to exist between testosterone or luteotrophic hormone and morphometric findings. Hence, FSH seems to characterise the severity of damage to germ epithelium and thus the degree of impairment to spermatogenesis. FSH may be accepted as a criterion for fertility disorders in sexually active men.
