A transvaginal ultrasound is a diagnostic procedure that uses sound waves to create detailed images of the uterus, ovaries, fallopian tubes, and pelvic area. A long, thin probe covered with a latex sheath and gel is inserted into the vagina to get a clearer view of pelvic organs and to diagnose conditions like pelvic pain, abnormal bleeding, infertility, cysts, fibroids, or to monitor pregnancy. The procedure is generally painless, involves no radiation, and requires you to empty your bladder beforehand.
