Verified step by step guidance

Step 1: Understand the role of the endometrium in the menstrual cycle. The endometrium is the inner lining of the uterus that thickens during the menstrual cycle to prepare for potential implantation of a fertilized egg.

Step 2: Review the hormonal regulation of the menstrual cycle. Key hormones involved include estrogen, progesterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Progesterone is particularly important for maintaining the endometrium after ovulation.

Step 3: Analyze the options provided. Cortisol is a stress hormone, insulin regulates blood sugar, and thyroxine is involved in metabolism. None of these are directly responsible for maintaining the endometrium during the menstrual cycle.

Step 4: Focus on progesterone. Progesterone is secreted by the corpus luteum after ovulation and plays a critical role in maintaining the thickened endometrium, ensuring it is ready for implantation.

Step 5: Conclude that progesterone is the hormone primarily responsible for maintaining the growth of the endometrium during the menstrual cycle, based on its physiological role.
