Endocervical epithelium from women treated with gonadotropin releasing horm
one agonist (GnRH agonist) were compared with those from untreated women, u
sing metachromatic stain with toluidine blue and immunohistochemistry, for
estrogen and progesterone receptors. Smaller endocervical epithelium with l
ower intraepithelial mucus and more prominent nuclear distribution of estro
gen receptors were seen in a woman who was treated for twelve months with G
nRH agonists, as compared with those from an untreated premenopausal woman.
