Question

About which day in a normal menstrual cycle does rapid secretion of LH (popularly called LH-surge) normally occurs?

• A. ${14}^{th}$ day
• B. ${20}^{th}$ day
• C. $5^{th}$ day
• D. ${11}^{th}$ day

Answer 1

The correct option is A ${14}^{th}$ day

For women with a 28-day cycle, the 14${}^{th}$ day is often the day of ovulation. A surge or sudden release of LH causes ovulation, the release of a mature ovum from the dominant ovarian follicle. After ovulation, LH stimulates the empty follicle to develop into the corpus luteum.
