Abstract

Ultrastructures of hypophyseal gonadotropes were studied in the hypophysis of the Korean native goat by electron microscopic immunohistochemistry with antisera to follicle stimulating hormone(FSH) and luteinizing hormone(LH). 1. Gonadotropes in the adenohypophysis were observed in the pars distalis and the pars tuberalis, but not in the pars intermedia. 2. FSH cells were round or oval in shape, and contained two types of round secretory granules, i.e., small and large granules. Small secretory granules were electron-dense and 180-275nm in diameter. Large secretory granules were less electron-dense than small granules and 485-555nm in diameter. 3. LH cells were round or oval in shape and also contained two types of secretory granules, the size of which were smaller than that of FSH cells. Small secretory granules were electron-dense and 160-230nm in size. The size of large secretory granules were 315-415nm with moderate electron densities.
