Verified step by step guidance1
Understand the phases of the menstrual cycle: The menstrual cycle is divided into four main phases: menstrual, follicular, ovulation, and luteal phases.
Identify the luteal phase: The luteal phase occurs after ovulation and before the start of menstruation. It typically lasts about 14 days.
Recognize the role of the corpus luteum: During the luteal phase, the corpus luteum forms from the remnants of the follicle that released the egg during ovulation. The corpus luteum secretes hormones, primarily progesterone, which helps maintain the uterine lining for a potential pregnancy.
Differentiate from other phases: The follicular phase is when the follicle matures, the ovulation phase is when the egg is released, and the menstrual phase is when the endometrium is shed.
Conclude the description: The luteal phase is characterized by the formation of the corpus luteum and the preparation of the endometrium for possible implantation of a fertilized egg.
