Ovulation typically occurs around day 14 of the female reproductive cycle, which is when estrogen levels have peaked and there is a surge of luteinizing hormone (LH) from the pituitary gland, as shown in the graph. This surge in LH triggers the release of an egg from the ovary. Therefore, based on the hormone levels shown in the graph, we would predict that ovulation would occur on day 14.
