Ben Wa balls are small marble-sized balls that can be used to strengthen the pelvic floor muscles and tighten the vagina. They are sometimes connected by a string or a silicone coating. Common uses for Ben Wa balls include sexual stimulation and improving bladder control. Gynecologists and Obstetricians recommend them along with Kegel exercises and vaginal weights to improve elasticity of the vagina an increase bladder control. Increasing weights can be used to strengthen the vagina and improve sexual performance and experiences. Bladder control issues, like that which occurs during coughing or sneezing and becomes more common as women grow older, or after childbirth, can be helped with the use of Ben Wa balls or Kegel exercises.
