It was established that high intensity and color indices were characteristic of cases of simple nonatypical HP with a gradual decrease to the complex atypical HP. There was marked increase in the expression levels of PR-receptor in accordance with the degree of ADCE differentiation. The absence of significant differences (p<0.05) was shown between the levels of expression of glandular and stromal components of PR-receptors in the foci of endometrioid heterotopias and in eutopic endometrium.
Prospects for future research are to compare the activity levels of estrogen and progesteron eutopic receptors in the endometrium and in the foci of endometrioid heterotopias for this category of women.
