Verified step by step guidance

Understand the role of each hormone listed in the options: Luteinizing hormone (LH), Estrogen, Progesterone, and Follicle-stimulating hormone (FSH).
Luteinizing hormone (LH) is crucial in the reproductive cycle, particularly in triggering ovulation. It is released by the anterior pituitary gland and causes the mature follicle to release an egg.
Estrogen is primarily involved in the regulation of the menstrual cycle and the development of secondary sexual characteristics. It helps prepare the uterine lining for potential pregnancy but does not directly trigger ovulation.
Progesterone is important for maintaining the uterine lining for a fertilized egg and is involved in the latter stages of the menstrual cycle, but it does not trigger ovulation.
Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles in the ovary before the release of an egg, but the surge in LH is what directly triggers ovulation.
