Verified step by step guidance

Understand the role of each hormone in the menstrual cycle: Follicle-stimulating hormone (FSH) is responsible for stimulating the growth of ovarian follicles in the ovary before the release of an egg at ovulation.

Recognize the role of estrogen: Estrogen is primarily involved in the regulation of the menstrual cycle and the development of female secondary sexual characteristics. It helps in the thickening of the endometrium and the regulation of FSH and LH levels.

Identify the function of luteinizing hormone (LH): LH is crucial for triggering ovulation, which is the release of a mature egg from the ovary. A surge in LH levels leads to ovulation.

Understand the role of progesterone: Progesterone is important for maintaining the uterine lining for a potential pregnancy after ovulation has occurred.

Conclude that the necessary trigger for ovulation is the surge in luteinizing hormone (LH), which is responsible for the release of the egg from the ovary.
