3. During days 12–14, however, estrogen provides positive feedback to the hypothalamus and pituitary gland. This causes a rapid rise in the production of estrogen by the ovaries and leads to ovulation. Another hormone involved in the menstrual cycle is progesterone.
4. Luteinising hormone, like follicle stimulating hormone, is a gonadotrophic hormone produced and released by cells in the anterior pituitary gland. It is crucial in regulating the function of the testes in men and ovaries in women.
5. After ovulation the ruptured follicle forms a corpus luteum that produces high levels of progesterone.
6. Menopause is a point in time 12 months after a woman's last period. The years leading up to that point, when women may have changes in their monthly cycles, hot flashes, or other symptoms, are called the menopausal transition, or perimenopause. The menopausal transition most often begins between ages 45 and 55.
7. Understanding your menstrual cycle, your menstrual cycle begins on the first day of your period and continues up to the first day of your next period. You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts.
Ovulation happens about 14 days before your period starts.
If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14.
If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19, 20 and 21.
8. Phase 1: The Follicular, or Proliferative Phase
The first phase of the menstrual cycle is the follicular or proliferative phase. It occurs from day zero to day 14 of the menstrual cycle, based on the average duration of 28 days.
9. In a normal 28 day menstrual cycle, when would you expect the LH surge to occur?
Question 10 Explanation: The LH surge usually occurs on day 12. This occurs due to oestrogen levels reaching a peak level which stimulates large amounts of LH production.
