Essay On Proliferative Endometrium

Proliferative Endometrium

The inner lining of the uterus is called the endometrium. This mucous membrane changes throughout the woman’s menstrual cycle. It becomes a proliferative endometrium before ovulation occurs as it develops into a thick layer that is rich with blood vessels to prepare the womb for pregnancy. If fertilization does not get occur, the endometrium is shed, which leads to menstrual bleeding.

Part 1: What Is Proliferative Endometrium?

The layer of tissue lining of the inner side of the uterus is called the endometrium. It provides a suitable environment for the implantation of a fetus. However, if pregnancy does not occur, this lining is shed off, resulting in bleeding or menstruation. The monthly shedding of the endometrium is followed by the growth of a fresh layer that prepares an environment for implantation if an egg is fertilized.

The proliferative phase occurs under the influence of the hormone estrogen, which stimulates endometrial growth and thickening. During this phase, the proliferative endometrium undergoes cell multiplication and tissue growth. If ovulation occurs, the body secretes a hormone called progesterone, which makes the endometrium thicker, creating an ideal environment for implantation of a fertilized egg. After implantation, the endometrium becomes a "secretory endometrium." This image shows a microscopic view of a normal secretory endometrium. There are large tortuous glands filled with secretions. This phase occurs on a 14-day course, which leads to either menstruation or implantation of a fertilized ovum. This image shows the microscopic appearance of a normal proliferative endometrium during the menstrual cycle. This phase is variable in length. During this phase, the tubular glands, which have columnar cells, and dense stroma proliferate and thicken, following the shedding off phase from a previous
