Quizplus · Accepted Answer

FSH (follicle-stimulating hormone) initiates the beginning of the ovarian cycle by promoting the development of follicles in the ovary. As the follicles develop, they secrete estrogen, which then stimulates further changes in the reproductive system. LH (luteinizing hormone) also plays a role in the ovarian cycle, but it is not responsible for initiating it. Progesterone is produced after ovulation and during pregnancy, but it is not involved in the initiation of the ovarian cycle.
