Study Notes
Ovarian Cycle
- During the ovarian cycle, primordial follicles are activated and begin to mature.
Maturing Ovarian Follicles
- The maturing ovarian follicles are called antral follicles.
Dominant Follicle
- The dominant follicle is the largest and most mature follicle during the ovarian cycle.
Follicle Development
- Follicles that do not become the dominant follicle undergo atresia, or degeneration.
Follicular Development
- The fluid that fills the cavity formed in the developing ovarian follicles is called antral fluid.
Dominant Follicle Growth
- The dominant follicle usually starts to grow rapidly around day 5-7 of the menstrual cycle.
Estrogen Production
- Granulosa cells are necessary for the production of estrogen in the ovary.
Luteal Phase
- The corpus luteum produces progesterone during the luteal phase of the menstrual cycle to prepare the uterus for implantation.
Corpus Luteum
- If pregnancy does not occur, the corpus luteum degenerates and progesterone levels drop, leading to menstruation.
