Penis pumps, also known as vacuum erection devices, are tools designed to help men achieve and maintain erections. These devices work by creating a vacuum around the penis, drawing blood into the erectile tissue and thus causing an erection. This mechanism can be particularly useful for men with erectile dysfunction (ED), a common condition where achieving or maintaining an erection is difficult. Studies have shown that penis pumps can be effective for men who do not respond well to oral ED medications such as sildenafil (Viagra) .
