Verified step by step guidance

Understand the process of ovulation: Ovulation is the release of a mature egg from the ovary, which occurs roughly midway through the menstrual cycle. Hormones play a critical role in regulating this process.

Identify the role of Luteinizing Hormone (LH): LH is a hormone produced by the anterior pituitary gland. It surges dramatically just before ovulation, triggering the release of the egg from the follicle.

Differentiate the roles of other hormones: Progesterone is primarily involved in preparing the uterus for implantation after ovulation. Estrogen helps regulate the menstrual cycle and promotes the growth of the uterine lining. Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles but does not directly trigger ovulation.

Recognize the timing of the LH surge: The LH surge typically occurs around day 14 of a 28-day menstrual cycle, signaling the ovary to release the mature egg.

Conclude that Luteinizing Hormone (LH) is the hormone responsible for triggering ovulation, based on its specific role in the process.
