How Does the Uterine Lining Change During the Menstrual Cycle?
The uterine lining goes through several phases during the menstrual cycle:
Menstrual Phase: If pregnancy does not occur, the outer layer of the endometrium sheds, leading to menstruation. Proliferative Phase: After menstruation, the endometrium regenerates and thickens in response to rising estrogen levels. Secretory Phase: Post-ovulation, progesterone levels rise, further thickening the endometrium and making it more receptive to a fertilized egg.
