A vaginal speculum is a metal or plastic device used during a pelvic exam. It is inserted into the vagina to open up and hold apart the sides, which allows the examiner to see the opening to the uterus (cervix).

A speculum is often used to collect samples of cervical cells for a Pap test (a screening test for cervical cancer). The health professional may also use a speculum to collect tissue samples from and examine the inside of the vagina.
