Occurrence of FSH, inhibin and other hypothalamic-pituitary-intestinal hormones in normal fertility, subfertility, and tumors of human testes.

Abstract

OBJECTIVE:

To compare the distribution of peptide hormones in presumably normal human testicular tissues and specimens exhibiting any of five pathologies.

METHODS:

Biopsies from patients having testicular malfunctions were prepared as sections and specifically immunohistochemically stained for inhibin, FSH, serotonin, AUP, and oxytocin.

RESULTS:

Immunocytochemical studies revealed the presence of various hypophysial-pituitary-intestinal hormones, viz., FSH, inhibin, arginine vasopressin (AVP), calcitonin, serotonin, oxytocin, adrenocorticotropin (ACTH), gastrin, secretin, and somatostatin in human testicular biopsies exhibiting normal spermatogenesis, Sertoli-cell-only syndrome, spermatogenic arrest, Leydig cell hyperplasia, Leydig cell tumor, and seminoma. Intensity of immunostaining for all peptides except FSH was stronger in cases of subfertile as compared to normal testis. Intensity of immunostaining with inhibin was maximum in Leydig cell tumor.

CONCLUSION:

These regulatory peptides may be involved in the pathophysiology of the testes.
