Abstract

At present, not much is known about progesterone receptor (PR) expression and localization in postmenopausal women ovaries. In the ovaries of reproductive age women, PR is localized in internal theca and granulosa cells, corpus luteum, ovary surface epithelium (OSE) and in stroma. PR expression depends on the serum concentration of progesterone, estrogen, gonadotropin and androgen. The goal of the conducted studies was to examine PR localization and expression in the ovaries of postmenopausal women who have not applied hormone replacement therapy so far. Also, the correlation was examined between PR expression and localization in the ovaries, steroid and gonadotropin hormone serum concentrations, and influence of the time from the last menstruation. The material came from 50 postmenopausal women who had their ovaries removed due to non-neoplastic diseases. The women were divided into 3 groups (A, B, C) depending on the time from the last menstruation. The follitropin (FSH), luteotropin (LH), estradiol (E2), testosterone (T), androstendione (A) and dehydroepiandrosterone sulphate (DHEAS) concentrations in blood plasma were measured. Monoclonal mouse anti-human PR antibody was used for immunohistochemical detection (examination involved 50 postmenopausal ovaries). Between particular groups, E2 serum concentrations did not differ, but FSH, LH, T, A, DHEAS serum concentrations were significantly different. Immunohistochemical nuclear localization of PR in postmenopausal women ovaries was observed. PR expression was similar in all three groups (A, B, C). PR expression was observed in OSE nuclei and invaginations cysts deriving from the isolation of invaginated epithelium and metaplastic columnar epithelium and in stroma. In the ovaries of postmenopausal women who have not applied hormone replacement therapy so far, PR was detected in all three groups. Its expression did not depend on the time from menopause and was similar in all examined groups. FSH, LH, T, A, DHEAS serum concentrations did not influence PR expression.
