How Much Do You Know About the Endometrium and Implantation?

• The uterus has three layers: endometrium, myometrium, and perimetrium.
• The endometrium undergoes changes in a 28-day cycle under hormonal control by the ovaries.
• The proliferative phase is under the influence of estrogen and parallels growth of the ovarian follicles.
• The secretory phase begins after ovulation in response to progesterone produced by the corpus luteum.
• If fertilization does not occur, shedding of the endometrium occurs during the menstrual phase.
• If fertilization occurs, the endometrium assists in implantation and contributes to formation of the placenta.
• At the time of implantation, the mucosa of the uterus is in the secretory phase.
• Three distinct layers can be recognized in the endometrium: a superficial compact layer, an intermediate spongy layer, and a thin basal layer.
• Normally, the human blastocyst implants in the endometrium along the anterior or posterior wall of the body of the uterus.
• The blastocyst becomes embedded between the openings of the glands in the endometrium.
