This question is testing your knowledge on ovulation.

During ovulation there will be increased estrogen, increased GnRH receptors on the anterior pituitary. Estrogen will continue to rise and then eventually this will stimulate LH surge --> ovulation (rupture of follicle). Increased temperature will also occur and this is (progesterone induced).

Also, keep in mind that there are two phases of the ovarian cycle:

• Follicular phase
• Luteal phase
