Question 41

Figure 1 shows the changes that occur in the hormone levels, the ovary, and the uterus lining during a typical 28-day menstrual cycle.

A three-panel diagram of the 28-day menstrual cycle. The top panel illustrates follicle development in the ovary, showing a developing follicle, a mature follicle, ovulation around day 14, and the formation of the corpus luteum. The middle panel shows pituitary hormone levels, highlighting a sharp peak in luteinising hormone (LH) on day 13. The bottom panel shows the thickness of the endometrium (uterus lining).

The level of luteinising hormone (LH) peaks on day 13.

State the effect of this peak in LH on the mature follicle.
