Because Prolifertaive phase is stimulated and sustained by estrogens secreted by the developing ovarian follicles (estrogen stimulates functional zone regrowth) However, cycle length may be as short as 21 days or as long as 40 days in some women. The inner lining of the uterus (the endometrium) goes through three phases during the typically 28 day menstrual cycle: the menstrual phase (days 1-5), the proliferative phase (days 6-14) and the secretory phase (days 15-28). In the proliferative phase, facilitated by FSH, the endometrium thickens, connective tissue is renewed, along with glandular structures and ehlicrine arteries.Oestrogen causes the endometrial stroma to become deep and richly vascularised. Simple tubular glands in the stratum functionalis open out onto the surface, and the endometrium thickens.
