Study Notes
- The menstrual cycle is a complex sequence of events that prepares the body for pregnancy, involving the ovaries and uterus.
- If pregnancy does not occur, the cycle ends with menstruation.
- The menstrual cycle typically lasts around 28 to 30 days, with variations from person to person.
- The cycle consists of four phases: menstruation, follicular, ovulatory, and luteal.
- Menstruation marks the beginning of the menstrual cycle, occurring around day 1.
- The follicular phase starts around day 5, characterized by rising estrogen levels.
- The ovulatory phase occurs around day 14, during which the ovary releases an egg to prepare for potential pregnancy.
- The luteal phase follows, marked by decreasing estrogen levels and increasing progesterone levels.
- If pregnancy occurs, progesterone levels remain high; if not, estrogen and progesterone levels decrease, leading to another menstrual cycle.
- Everyone's experience with menstruation is unique, and becoming familiar with one's body can help identify individual patterns.
