Endometrial polyps are usually benign although some may be precancerous or cancerous. [3] About 0.5% of endometrial polyps contain adenocarcinoma cells. [14] Polyps can increase the risk of miscarriage in women undergoing IVF treatment. [3] If they develop near the fallopian tubes, they may lead to difficulty in becoming pregnant. [3]
During implantation, the embryo must cross the epithelial layer of the maternal endometrium before invading and implanting in the stroma layer. Maternal factors, including congenital uterine abnormalities, fibroids, endometrial polyps, intrauterine adhesions, adenomyosis, thrombophilia and endometriosis, can reduce the chances of implantation and result in RIF.
Endometrial: Endometrial causes of abnormal bleeding include infection of the endometrium, endometritis, which may occur after a miscarriage (spontaneous abortion) or a delivery, or may be related to a sexually-transmitted infection of the uterus, fallopian tubes or pelvis generally termed pelvic inflammatory disease (PID). Other endometrial ...
Endometrial polyp; Painful (i.e. associated with dysmenorrhea): Pelvic inflammatory disease; Adenomyosis - extension of the endometrial tissue into the outer muscular wall of the uterus which can cause pain and abnormal bleeds when the endometrium sheds; Pregnancy related complication (i.e. miscarriage) Short cycle (less than 21 days) but ...
Under the influence of estrogen the endometrium (uterine lining) is stimulated and eventually such lining will be shed off (estrogen breakthrough bleeding). The anovulation chapter discusses its multiple possible causes. Longstanding anovulation can also lead to endometrial hyperplasia and facilitate the development of endometrial cancer.
D&Cs can be performed on people who have a polyp on their uterus or a retained placenta after childbirth or to help control bleeding, Streicher says. In the case of a miscarriage, the D&C is often ...
Acquired: Other structural uterine anomalies such as uterine fibroids, polyps, and adhesions (also known as Asherman's syndrome) have a less clear association with recurrent pregnancy loss. [3] Cervical weakness has been shown to lead to premature pregnancy loss resulting in miscarriages or preterm deliveries.
Besides the aforementioned physiologic forms, IMB may also represent abnormal uterine bleeding and be a sign of an underlying disorder, such as a hormone imbalance, endometriosis, uterine fibroids, uterine cancer, or vaginal cancer. [citation needed] If the bleeding is repeated and heavy, it can cause significant iron-deficiency anemia.
