Adenomyosis is a medical condition characterized by the growth of cells that proliferate on the inside of the uterus (endometrium) atypically located among the cells of the uterine wall , [2] as a result, thickening of the uterus occurs. As well as being misplaced in patients with this condition, endometrial tissue is completely functional.
Increased estradiol alters the endometrial lining and promotes proliferation of epithelial cells, thickening of the tissue, and elongation of the spiral arteries that provide nutrients to the growing tissue. Estrogen also makes the endometrium more sensitive to progesterone in preparation for the luteal phase. [citation needed]
An endometrial polyp or uterine polyp is a mass in the inner lining of the uterus. [1] They may have a large flat base or be attached to the uterus by an elongated pedicle (pedunculated). [2] [3] Pedunculated polyps are more common than sessile ones. [4] They range in size from a few millimeters to several centimeters. [3]
Endometrial hyperplasia is a condition of excessive proliferation of the cells of the endometrium, or inner lining of the uterus. Most cases of endometrial hyperplasia result from high levels of estrogens , combined with insufficient levels of the progesterone-like hormones which ordinarily counteract estrogen's proliferative effects on this ...
Pain and infertility are common symptoms, although 20–25% of affected women are asymptomatic. [1] Presence of pain symptoms are associated with the type of endometrial lesions as 50% of women with typical lesions, 10% of women with cystic ovarian lesions, and 5% of women with deep endometriosis do not have pain.

Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
“This tissue is responsive to a woman's normal hormonal cycle and thus grows and bleeds just like the uterine lining, which over time causes inflammation and scarring of pelvic tissues.
In the early stages of infection, the ultrasound may appear normal. As the disease progresses, nonspecific findings can include free pelvic fluid, endometrial thickening, uterine cavity distension by fluid or gas. In some instances the borders of the uterus and ovaries appear indistinct.
