Examples
- The luteal phase is also known as the secretory phase, characterized by increased progesterone levels in the blood.
- During the secretory phase of the menstrual cycle, the uterine lining thickens in preparation for a fertilized egg.
- In a normal menstrual cycle, the secretory phase usually lasts about 12 to 14 days.
- Hormones produced by the corpus luteum during the secretory phase help maintain uterine lining for potential implantation.
- If implantation does not occur, the corpus luteum degenerates, ending the secretory phase and triggering menstruation.
