Pituitary-gonadal function in chronic renal failure: the effect of luteinizing hormone--releasing hormone and the influence of dialysis.
Sixteen adult male patients with chronic renal failure undergoing either chronic intermittent hemodialysis (HD) or chronic intermittent peritoneal dialysis (PD) were studied both before and immediately after dialysis. The gonadotropin responses to luteinizing hormone-releasing hormone (LH-RH) was determined, revealing an excessive luteinizing hormone (LH) response with a delayed return to normal in both dialysis groups. No significant alteration in follicle-stimulating hormone (FSH) kinetics was observed. There was no significant difference in the mean gonadotropin responses to LH-RH between the HD and PD groups, and dialysis had no effect on either mean LH or FSH responses. The chronic renal failure patients with testicular atrophy had an excessive FSH response to LH-RH when compared to those patients without testosterone was significantly lower than normal. Chronic renal failure effects testicular function and testicular atrophy is associated with seminiferous tubular destruction and an excessive FSH response. Poor renal clearance may play a role in the abnormal LH response observed.
