What does the LH and FSH graph reveal about the hormonal levels during the menstrual cycle?

The LH and FSH graph shows that levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) fluctuate during the menstrual cycle. LH spikes just before ovulation, triggering the release of the egg, while FSH helps stimulate the growth of follicles in the ovaries. These hormone changes are essential for regulating the menstrual cycle and fertility.
