Kegel Balls: how they work, how to choose and use them

Geisha balls—also known as Kegel balls, vaginal eggs, or Ben Wa balls—are among the oldest intimate accessories in the world. Used for centuries in Asia to strengthen the pelvic floor, they have seen a considerable resurgence in interest in recent years, particularly driven by their portrayal in popular culture. But beyond the fantasy, what do geisha balls really do, and how do you choose the right ones?

How do geisha balls work?

Geisha balls are small spheres—usually two connected by a cord—designed to be inserted into the vagina. Some models contain an internal ball that moves freely, creating slight vibrations with every body movement. Others are solid and smooth.

Their primary benefit is strengthening the pelvic floor—the muscles that support the bladder, uterus, and rectum. By keeping the balls in place, these muscles work in constant contraction, which progressively strengthens the perineum with regular use.

Tangible benefits

A strengthened perineum offers several measurable advantages: a reduction in urinary leakage (very common after childbirth or with age), improved sensitivity during intercourse, and better control of contractions during orgasm. Some women also report sensations of mild stimulation while wearing them, linked to the micro-movements of the internal ball.

These benefits are not immediate—they develop with regular use over several weeks, like any muscle exercise.

How to choose your first geisha balls?

For first-time use, several criteria should be considered.

Weight is the first parameter: start light—between 25 and 50 grams. Balls that are too heavy for an untrained perineum can be uncomfortable and difficult to hold. Gradually increase the weight over the weeks.

Size also affects comfort: larger balls are easier for beginners to hold, as they require less muscular effort. Smaller balls require more muscular work and are suitable for more experienced users.

The material is non-negotiable: exclusively choose medical-grade silicone, stainless steel, or borosilicate glass—non-porous materials that are easy to disinfect and safe for mucous membranes. Avoid plastic balls or those made of unidentified materials.

The presence of a retrieval cord is recommended for beginners—it allows the balls to be removed easily and safely.

How to use them?

Start with a short session—15 to 20 minutes—while standing or walking lightly. For the first few times, focus simply on keeping the balls in place without excessive effort. With practice, you can gradually extend the duration up to an hour.

Use a water-based lubricant to facilitate insertion. After each use, carefully clean the balls with warm soapy water—models made of medical-grade silicone, glass, and metal can be sterilized in boiling water.
