A device (10) for stretching the foreskin of a subject is disclosed. The device has a body (10) having a passage (14) that extends through the body (10) to a distal end (18). The distal end (18) is adapted to receive a balloon (B). Fluid may be introduced through the passage (14) to cause the balloon (B) to expand. A flow regulating member (20) is positioned across the passage (14) to selectively close the passage (14) to fluid flow.
