Immunohistochemical Localization of Aromatase in Goat Testicular Tissue and Accessory Glands

The aim of the present study was to immunohistochemical localization of Cytochrome P450 Aromatase in male goat reproduction system. Aromatase is a terminal enzyme which transforms androgens in to estrogens. This study investigated the immunohistochemical localization of aromatase in native male goat testis, efferent ductules of epididymis, vesicle seminal and prostate glands using polyclonal anti aromatase antibody as primary antibody and anti-mouse IgG (HRP) Polyclonal antibody as secondary antibody. Samples of testis and accessory glands collected from five native male goat (2-4 years old), and for IHC test were kept in Bowen solution. Then paraffin block and histological section for IHC test were prepared. Immunoreactions was observed in stages of spermatogenesis, Leydig cells, efferent ductules of epididymis, cytoplasm of vesicle seminal and prostate glands cells. The results show that aromatase in testicular cells and sexual glands converts androgens to estrogens and may be locally estrogens have a paracrine and autocrine activates in reproductive tract.
