Uterus: pre-menstrual phase (Days 26-28)
The corpus luteum decreases hormone production, causing the endometrium to shrink, becoming less edematous. Alternate contraction and relaxation of spiral arteries results in ischemia and degeneration of endometrial tissue supplied by these vessels. This phase is also called the ischemic portion of the secretory phase. 10x
