A vaginal speculum is a medical instrument which is used to dilate the vagina for examination of the vagina and cervix. This medical instrument can also be used in examinations of the anus, although specialized anal specula are also available. Numerous medical instrument manufacturers produce vaginal specula, which are available for sale through medical supply catalogs. Some women's health centers also sell these devices to their patients, for patients who are interested in performing vaginal self exams.

Specula in general are a family of medical instruments which are used to visualize the interior of the body by inserting the instrument to get a better view. In the case of a vaginal speculum, the instrument includes a blade which is gently inserted and used to dilate the vagina to make it easier to see. Classically, doctors use a two-bladed speculum which resembles the bills of a duck, with a locking handle to manipulate the blades, although single blade vaginal specula are also available.

Clear plastic specula are preferred for examination, because it is easier to visualize the area when using a plastic speculum. These specula are disposable, designed to be discarded after use with a patient. Metal specula are also available, and must be cleaned and autoclaved between patients. Vaginal specula come in several different sizes, to accommodate women with vaginas of various sizes. Especially small versions can be used for examinations when a woman has an intact hymen.

A specialized form of vaginal speculum is the weighted speculum, which consists of a broad half tube which is bent at about a 90 degree angle, with the channel of the tube on the exterior side of the angle. One end of the tube has a roughly spherical metal weight surrounding the channel of the speculum. A weighted speculum is placed in the vagina during vaginal surgery with the patient in the lithotomy position. The weight holds the speculum in place and frees the surgeon's hands for other tasks. A vaginal speculum is also used in fertility treatments, particularly artificial insemination, and allows the vaginal cavity to be opened and observed thereby facilitating the deposit of semen into the vagina.
