How does progesterone effect endometrium?
If the egg is fertilised, progesterone stimulates the growth of blood vessels that supply the lining of the womb (endometrium) and stimulates glands in the endometrium to secrete nutrients that nourish the early embryo.
Where is the endometrium?
The endometrium is the innermost lining layer of the uterus, and functions to prevent adhesions between the opposed walls of the myometrium, thereby maintaining the patency of the uterine cavity. During the menstrual cycle or estrous cycle, the endometrium grows to a thick, blood vessel-rich, glandular tissue layer.
What is the normal size of endometrium?
For women of reproductive age, the endometrial stripe thickens and thins according to their menstrual cycle. The stripe can be anywhere from slightly less than 1 millimeter (mm) to slightly more than 16 mm in size.
