Immunohistochemical localization of endometrial oestrogen and progesteronereceptors in the cow

The presence and distribution of oestrogen and progesterone receptors have been investigated by means of immunohistochemical procedures in the uterus of two groups of cows: the first group underwent superovulatory hormonal tr eatment while the second group was used as a control group. After the immun ohistochemical study no differences regarding the presence and distribution of hormone receptors seemed to be apparent between the two groups, so it w as concluded that the topographical distribution and staining intensity of hormone receptors seem to be unaffected by hormonal superovulatory treatmen t.
