biopsy, endometrial

biopsy, endometrial A procedure for sampling the lining of the uterus (the endometrium). Endometrial biopsy is usually done to detect the cause of abnormal uterine bleeding, but it may be used to determine the cause of infertility, test for uterine infections, and even monitor responses to certain medications. The procedure can be done in a physician’s office. There are few risks, the most common being cramping and pain. Oral pain medications taken beforehand may help reduce cramping and pain.
