How Well Do You Know the Endometrium and Menstrual Cycle?

• The uterus has three layers: endometrium, myometrium, and perimetrium.
• The endometrium is rich in simple tubular glands.
• The menstrual cycle lasts approximately 28 days and is under hormonal control by the ovaries.
• The proliferative phase is influenced by estrogen and parallels growth of ovarian follicles.
• The secretory phase begins after ovulation in response to progesterone from the corpus luteum.
• If fertilization does not occur, the endometrium sheds (menstrual phase).
• If fertilization occurs, the endometrium assists in implantation and contributes to the placenta.
• The endometrium has three layers during implantation: compact, spongy, and basal.
• The blastocyst implants in the endometrium along the anterior or posterior wall of the uterus.
• The blastocyst becomes embedded between the openings of the glands in the endometrium.
