Short answer: explain the stages of menstrual cycle and what is happening in pituitary, ovary and endometrium in each stage:
- (day 5-14)
- Pituitary/Hypothalamus: GnRH increases and FSH/LH increases as well.
- Ovary: Foolicles continue to mature; Estrogen produced by maturing follicles causes......
- Endometrium: grows thicker layers to replace old cells lost; spiral arteries grow, uterine milk grows
As estrogen goes up, feedback stops more follicles from growing.
