abnormal growth of the lining of the uterus outside the uterus is called
Adenomyosis Adenomyosis is a gynecologic medical condition characterized by the abnormal presence of endometrial tissue (the inner lining of the uterus) within the myometrium (the thick, muscular layer of the uterus).[1] In contrast, when endometrial tissue is present entirely outside the uterus, it represents a similar but distinct medical condition called endometriosis. The two conditions are found together in many cases,[2][3] but often occur independently. Before being recognized as its own condition, adenomyosis used to be called endometriosis interna. Additionally, the less-commonly used term "adenomyometritis" is a more specific name for the condition, specifying involvement of the uterus.[4][5]
Menstrual cycle The proliferative phase is the second phase of the uterine cycle when estrogen causes the lining of the uterus to grow, or proliferate, during this time.[81] As they mature, the ovarian follicles secrete increasing amounts of estradiol, and estrogen. The estrogens initiate the formation of a new layer of endometrium in the uterus, histologically identified as the proliferative endometrium. The estrogen also stimulates crypts in the cervix to produce fertile cervical mucus, which may be noticed by women practicing fertility awareness.[101]
