The video shows a diagram of a woman's reproductive system, including the ovaries, fallopian tubes, and uterus. The diagram is color-coded, with the ovaries and fallopian tubes in pink and the uterus in blue. There are arrows indicating the flow of hormones, with estrogen and follicle-stimulating hormone (FSH) shown in blue and luteinizing hormone (LH) in green. The diagram also includes a brain, suggesting the role of the brain in hormone production. The video cycles through different frames, each showing the same diagram with slight variations in the position of the arrows and the labels.
