* NOTE: We use the term “kegel balls” here, but terms such as "Ben-Wa balls, Geisha balls, vaginal balls, pelvic floor training balls" are also suitable in this context.

In this guide, I will share my professional tips as a former midwife and certified pelvic floor therapist on how to use kegel balls* for postpartum recovery after pregnancy and childbirth. You’ll learn how these tools can help prevent or improve pelvic floor weakness – and, most importantly, which kegel balls* are actually effective. There are only a few that are truly suitable for this purpose, and they are available not only in sets but also individually. Certified medical kegel balls* with proven effectiveness are not the cheapest, but they are worth every penny.

Take some time to understand the basics:

Pregnancy and childbirth are natural events that a woman’s body is designed for. Yet, these experiences put intense strain on the pelvic floor, often leading to weakness. That’s why I strongly recommend that all women start targeted training after childbirth to prevent pelvic floor weakness as early as possible. Using kegel balls* during pregnancy, however, is not advisable.

Many sex toy manufacturers have discovered “pelvic floor training” as a new market. You’ll find countless products in attractive designs and colors, all promising better sexual pleasure and help with pelvic floor weakness (including postpartum recovery).

However, the quality of kegel balls* varies enormously – both in terms of material and the intensity of the vibrations generated by the inner ball.

We will get to the criteria that make kegel balls* truly effective for pelvic floor training. But first, let’s look at the basics:

The function of the female pelvic floor

The pelvic floor of a woman has done amazing work during pregnancy and childbirth: it has carried significant extra weight in addition to its usual tasks – supporting and holding pelvic organs, ensuring upright posture, and controlling bladder and bowel functions. This extra weight includes not only the baby but also amniotic fluid, the growing uterus, and the placenta.

Pregnancy hormones make tissues like tendons, ligaments, and the pelvic floor itself softer and more flexible. For childbirth, the pelvic floor needs not only strength but also elasticity and flexibility. Psychologically and spiritually, a healthy pelvic floor provides a feeling of inner stability.

In sexuality, a healthy pelvic floor is crucial: It allows the vagina to open, hold, and massage the partner’s penis during intercourse. A cesarean section can negatively affect the pelvic floor, as it is connected to the abdominal muscles, which are cut during surgery. This weakens the overall structure and makes training more challenging.

The consequences of pelvic floor weakness

Weak pelvic floor muscles can lead to various issues, with urinary incontinence being the most common. This can be embarrassing and distressing for women. Fecal incontinence, though less common, has an even greater impact on daily life and self-confidence. High-impact sports such as running, ball sports, or trampoline exercises should be avoided because they put extra strain on a weakened pelvic floor. (Side note: Nordic walking with Viball® is a real miracle workout!)

Poor posture often accompanies pelvic floor problems. This can lead to chronic back pain, especially in the lower spine. Additionally, pelvic organ prolapse – where the uterus, bladder, or bowel descends – can occur, leading to inflammation and discomfort during sex due to a "too wide" vaginal opening.

Which kegel balls* help after pregnancy?

After childbirth, targeted training to rebuild and strengthen the pelvic floor is essential. A postnatal course with other mothers is ideal, but extra home training will boost results significantly. I have developed special pelvic floor exercises with Viball® (see below) that strengthen both the pelvic floor and the surrounding muscles. It’s also important to check your everyday movements and habits for pelvic floor-friendly behavior and make adjustments as needed.

Besides exercises, vaginal devices can be very effective. Vaginal cones (weights in a conical shape) are well-known but can cause tension and are often too small to stay in place. That’s why they are not ideal for postpartum training.

Better suited are kegel balls*: Hollow balls with an inner ball that moves and vibrates with your movements, stimulating the pelvic floor. They combine both weight and vibration effects. However, not every product marketed as a “love ball” or “geisha ball” is of sufficient quality to provide real therapeutic benefits.

1. The weight helps train the muscles – just like strength training at the gym.
2. When worn during everyday activities, the vibrations remind you to engage your pelvic floor consciously, improving your posture and movement.
3. The vibrations trigger reflex contractions of the pelvic floor muscles, especially the fast-twitch fibers, which helps reduce incontinence.
4. The subtle impulses act as a constant reminder to do a few strong contractions during the day.
5. Erotic stimulation from kegel balls* also leads to contractions that speed up recovery and tone the pelvic floor.

Kegel balls* for pelvic therapy must meet these criteria:

1. Multiple sizes and weights – because every woman’s body is different. Three sizes are common but far from sufficient!
2. High vibration intensity – not just promised, but proven.
3. Body-safe materials: Long-term use requires a hygienic, non-toxic material. Unfortunately, many cheap products fail here – tests show that many contain harmful substances.
4. Certification as a medical device: Only certified medical kegel balls* prove their safety and effectiveness.

Does this mean medical device or sex toy? Not at all: Medical devices can also be used for erotic play – and with even better sensations!

Up until now, there was no true “medical-grade kegel ball” that met all these criteria. That’s why I developed Viball®.

Viball® is a certified medical product with proven results. Don’t settle for cheap compromises when it comes to the most intimate part of your body.

Why Viball® kegel balls* work so effectively

1. Six sizes – for every woman

To ensure perfect adaptation to your body and to different training goals, Viball® is available in six different sizes and weights – whether for young women, for use during menopause, or after multiple births.

The crucial factor is the ratio between the size of the outer ball and the size of the inner ball: if the inner ball is too large, it doesn’t have enough space to swing; if it is too small, it lacks the weight needed for a powerful vibration. Most sex toys do not meet this requirement, resulting in weak vibrations.

2. The vibration intensity of Viball® is unmatched

With Viball®, the ratio of inner to outer ball is calculated precisely for each of the six sizes. This results in maximum vibration intensity, further enhanced by the unique ability of stainless steel to transfer vibrations optimally to the body. Simply put: it’s impossible to generate more vibration in a ball of the same size than with a Viball®.

3. Viball® is made from high-quality implant-grade steel

Most erotic products are made from silicone. But silicone is not inert – it changes over time: it discolours, releases chemical components, and can absorb odours. In addition, its surface becomes rougher with every cleaning, creating an environment for bacteria.
That’s why Viball® is made from implant-grade stainless steel: hypoallergenic, 100% biocompatible, and permanently hygienic. The perfectly polished surface makes the balls exceptionally easy to insert and remove.

4. Viball® moves freely inside the vagina

Conventional kegel balls usually come in sets of two, joined by a connector in the shape of a figure eight. This design means they get “stuck” in one position due to muscle tension. External covers or retrieval cords – which are supposedly needed – restrict this mobility even further. In contrast, the free movement of Viball® provides additional stimulation, which can also gently massage scar tissue.

5. Maximum hygiene & safety – no retrieval cord

Retrieval cords or loops on conventional kegel balls can increase the risk of infections, especially in the postpartum phase. They act like a bridge for germs, leading to vaginal infections or thrush. Viball® has no retrieval cord, so your vagina can fully “embrace” it, and the ball can move naturally up and down due to your muscle tone. This gentle movement also supports healing from tears or scars after birth.

But how do you remove it?
Viball® can be easily removed under normal conditions. For rare cases where assistance is needed, special application sleeves are available. Using a small amount of the included pjur med lubricant makes insertion smoother. You’ll find all details in the user manual and our FAQ.

6. Viball® is invisible to others

You can wear Viball® anytime and anywhere – even in the sauna or during sports – because it remains completely inside your body and is invisible to others.

7. Viball® is a certified medical device

Viball® meets all requirements for a medical-grade kegel ball, including proven effectiveness, biocompatibility, and safety – even without retrieval cords. This makes it not only a high-end training device for your pelvic floor but also your personal pleasure product de luxe.

How to use kegel balls* correctly

Whether you want to use kegel balls* for pelvic floor recovery after childbirth or for erotic stimulation – both have a positive effect on a healthy pelvic floor. Apply a small amount of lubricant (we recommend pjur med) and insert the ball gently. Wear it during daily activities, especially when moving or doing sports, as this is when Viball® works most effectively. Smooth-flowing exercises like yoga, walking, dancing, or gentle gymnastics are perfect. Avoid high-impact sports such as jumping or trampoline workouts during your postpartum recovery phase.

How to choose the right size

(Too) small kegel balls* often lead to unintentional tension because the muscles work to prevent them from slipping out – plus their training effect is weaker. To ensure both effectiveness and safety, the size must be just right. Every vagina is different due to age, childbirth, and individual anatomy. “One size fits all” is definitely a no-go!
