Verified step by step guidance1
Understand the menstrual cycle phases: The menstrual cycle is divided into the follicular phase, ovulation, and the luteal phase. Each phase is regulated by different hormones.
Identify the role of each hormone: Estrogen helps in the growth of the uterine lining, Follicle-stimulating hormone (FSH) stimulates the growth of ovarian follicles, Luteinizing hormone (LH) triggers ovulation, and Progesterone prepares the uterus for a potential pregnancy.
Focus on the ovulation phase: Ovulation is the release of an egg from the ovary, and it is a key event in the menstrual cycle.
Determine the hormonal trigger for ovulation: The surge in Luteinizing hormone (LH) is the primary trigger for ovulation, causing the mature follicle to release an egg.
Conclude the sequence of hormonal changes: Just before ovulation, there is a significant increase in LH levels, known as the 'LH surge,' which is crucial for the ovulation process.
