Verified step by step guidance

Begin by understanding the role of hormones in the menstrual cycle. The menstrual cycle is regulated by a complex interplay of hormones that prepare the body for potential pregnancy.

Identify the key hormones involved in the menstrual cycle: estrogen, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Each of these hormones has specific functions at different stages of the cycle.

Focus on progesterone and estrogen, as these are the primary hormones that coordinate the menstrual cycle. Estrogen is responsible for the thickening of the uterine lining, while progesterone stabilizes the lining and prepares it for potential implantation of a fertilized egg.

Understand the phases of the menstrual cycle: the follicular phase, ovulation, the luteal phase, and menstruation. Progesterone levels rise during the luteal phase, which follows ovulation, to maintain the uterine lining.

Conclude that progesterone is crucial for coordinating the menstrual cycle, particularly in the luteal phase, by maintaining the uterine lining and supporting potential pregnancy. Estrogen also plays a significant role, but progesterone is key in the latter part of the cycle.
