Study Notes
Ovarian and Endometrial Cycles
- The pituitary gland releases hormones that regulate the ovarian and endometrial cycles in females
- The ovarian cycle lasts approximately 28 days
- The endometrial cycle is synchronized with the ovarian cycle and also lasts approximately 28 days
- The ovarian and endometrial cycles typically begin in females around age 10-12
- A female is born with approximately 1-2 million primary follicles
- Only one primary follicle reaches maturity during each ovarian cycle
- The purpose of the ovarian cycle is to prepare the body for a possible pregnancy
- Menopause, the cessation of ovulation, typically occurs in females between the ages of 45 and 55
- Ovulation occurs during the follicular phase of the ovarian cycle
- FSH (follicle-stimulating hormone) stimulates the secretion of estrogen from the ovary
- The corpus luteum is responsible for secreting progesterone, which prepares the uterus for implantation
- Progesterone has a negative feedback effect on the pituitary gland to stop secreting LH and FSH
- If fertilization does not occur, the corpus luteum degenerates
- The anterior pituitary gland secretes FSH, LH, prolactin and TSH
- After ovulation, the ovum has approximately 12-24 hours to unite with a sperm in the uterine tube
