Study Notes
Ovarian Cycle: Overview
- The ovarian cycle is controlled by central hormones FSH and LH.
- The ovary responds by forming the ovarian cycle.
Follicular Phase
- Follicles grow in the ovary and release estrogen under the influence of FSH.
Ovulation
- The dominant follicle releases the ovum.
Luteal Phase
- The dominant follicle transforms into the corpus luteum, which releases progesterone.
- This process leads to menstruation.
- If the released ovum is fertilized, pregnancy occurs.
- The resulting embryo releases human chorionic gonadotropin (HCG), which helps maintain the pregnancy by preventing the loss of the corpus luteum.
- The corpus luteum of pregnancy releases estrogen and progesterone.
- The placenta forms after 3 months.
Hormones Involved
- GnRH (Gonadotropin-releasing hormone)
- FSH (Follicle-stimulating hormone)
- LH (Luteinizing hormone)
- Estrogen
- Progesterone
- HCG (Human chorionic gonadotropin)
Ovarian Cycle Diagram
- The diagram shows fluctuating levels of LH and FSH over time.
- The diagram also shows development of follicles within the ovary, ovulation process and the formation of the Corpus Luteum.
- Different stages of the cycle are labeled and stages of the development of the ovum are shown, including the Corpus Luteum.
