THE MENSTRUAL CYCLE Phases of the endometrium development: Proliferative phase Secretory phase Menstrual phase Atrophic endometrium After the menopause the number of the glands and the quantity stroma progressively decrease The remaining gland are oriented parallel to the surface, the stroma contains abundant collagen The glands are often dilated senile cystic atrophy of the endometrium

PROLIFERATIVE PHASE During the first day of the menstrual cycle the endometrium is under estrogenic stimulation The glands are coiled proliferative progress more coiled pseudostratified columnar watery alkaline secretion facilitate passage of the sperm from endometrial cavity to fallopian tubes

SECRETORY PHASE Ovulation graafian follicle becomes corpus luteum granulosa cells luteinize begin to secrete

SECRETORY PHASE Ovulation graafian follicle becomes corpus luteum granulosa cells luteinize begin to secrete progesteron transformation of endometrium from proliferative into a secretory state Days 17 -19 (postovulatory days 3 -5) more coiled subnuclear vacuoles scretion to support the zygote Days 20 -22 (postovularory days 6 -8) the endometrium displays prominent glandular secretions and stromal edema. The glands dilate and more tortuous Day 23 (postovulatory day 9) predecidual Day 27 (postovulatory day 13) full thickness of stroma is pre-decidualized and prepared for mentruation. The glands continua to dilate and develop serrated (saw -tooth) border

MENSTRUAL PHASE Absence of pregnancy no blastocyst to elaborate h. CG granulosa & theca cells of the corpus luteum degenerate progesterone level fall - endometrium desiccated - spiral arteries collapse - stroma disintegrates Menses commences on day 28, last 3 or 7 days, and result in a flow of about 35 ml of blood The denuded surface is re-epithelialized by extension of the residual glandular epithelium
