A vaginal probe is a small, wand-like medical device inserted into the vagina, primarily for transvaginal ultrasounds (TVS) to get detailed images of pelvic organs (uterus, ovaries, fallopian tubes) for diagnostics like pregnancy, pain, or infertility, and also used for pelvic floor muscle therapy (biofeedback/stimulation) for issues like incontinence. These probes are covered with a condom and gel for hygiene and smooth insertion, allowing doctors to visualize anatomy better than with external scans.
