The top row shows the evolving ovarian histology beginning with follicular development through ovulation to formation and finally degeneration of the corpus luteum. The second row shows changes in body temperature, which peaks during ovulation. The third row shows changes in reproductive hormones: leutenizing hormone, follicle-stimulating hormone, estradiol, and progesterone.
