What Is the Key by Jopen Stella I Kegel Ball Set?
The kegel ball set from Key by Jopen — the Stella I in Robin Egg Blue — is a single, body-safe device designed to support pelvic floor muscle training in a gentle, progressive way. Pelvic floor health matters more than many people realise. Weak pelvic floor muscles are linked to stress urinary incontinence, reduced core stability, and changes in sexual sensation — all of which can significantly affect quality of life. The NHS recognises pelvic floor exercises as a first-line approach for managing these concerns, particularly in women who have given birth or are approaching menopause.
Priced at just £23.49, this product sits within our women's health range and offers an accessible entry point for anyone new to pelvic floor training. The robin egg blue colourway is discreet and appealing, and the single-ball design makes it ideal for beginners who want to build confidence before progressing to heavier or multi-ball options.
How Does the Stella I Kegel Ball Work?
The mechanism is straightforward but effective. When inserted vaginally, the ball creates a gentle internal resistance. Your pelvic floor muscles naturally engage to hold it in place — essentially performing a sustained, low-level contraction without you having to think about it consciously. Over time, this passive engagement builds muscle endurance and tone.
- The ball is inserted into the vaginal canal using a water-based lubricant.
- Pelvic floor muscles contract reflexively to retain the ball during movement.
- Sustained muscle engagement over 15–30 minutes per session builds progressive strength.
- Regular use over weeks leads to measurable improvements in muscle tone and bladder control.
Who Should Use the Stella I Kegel Ball Set?
This product is designed for adults who want to take a proactive approach to pelvic floor health. It's particularly well-suited to those who find traditional kegel exercises difficult to perform correctly — the physical feedback from the ball helps you engage the right muscles. That said, it's not appropriate for everyone, and you should always check with a healthcare professional if you're unsure.
- Adults experiencing mild stress urinary incontinence (leaking when coughing, sneezing, or exercising).
- Those recovering from childbirth, once cleared by a midwife or GP.
- People approaching or going through menopause, when pelvic floor changes are common.
- Anyone wanting to improve pelvic floor strength as part of a general wellness routine.
How Does the Stella I Compare to Other Kegel Devices?
| Feature | Stella I Single Kegel Ball | Double Kegel Ball Set |
|---|---|---|
| Number of balls | 1 | 2 |
| Resistance level | Light — ideal for beginners | Moderate to high |
| Ease of insertion | Easier — smaller profile | Slightly more complex |
| Recommended for | Beginners and post-partum (with GP clearance) | Intermediate to experienced users |
Is the Stella I Kegel Ball Set Clinically Suitable for You?
If you have a history of pelvic organ prolapse, recurrent pelvic infections, or have recently undergone pelvic surgery, you must speak to your GP or a women's health physiotherapist before using any kegel ball set. The same applies if you are pregnant — internal devices are not recommended during pregnancy without explicit medical guidance. For those with bladder or urinary tract concerns, it's worth discussing whether pelvic floor training is appropriate alongside any ongoing treatment.
Store the device in its provided pouch, away from direct sunlight and extreme temperatures. Clean it thoroughly before and after each use with a toy-safe cleaner or mild soap and warm water. Never use silicone-based lubricants with this product — always opt for a water-based alternative.
This product is a wellness device, not a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Key by Jopen Stella I Single Kegel Ball Set - Robin Egg Blue
What Is the Stella I Kegel Ball Set and What Is It Used For?
The Key by Jopen Stella I Single Kegel Ball Set is a non-pharmacological pelvic floor training device intended for adult use. It is used to strengthen the pelvic floor muscles — the group of muscles and connective tissues that support the bladder, bowel, and uterus. Weak pelvic floor muscles can contribute to stress urinary incontinence (leaking urine when you cough, sneeze, or exercise), reduced sexual sensation, and pelvic organ prolapse risk. The NHS recommends pelvic floor exercises as a first-line intervention for these concerns.
This device works by providing gentle internal resistance during everyday movement, encouraging the pelvic floor to engage passively. It is not a medical treatment and does not replace professional pelvic floor physiotherapy where that is clinically indicated.
What Do You Need to Know Before Using the Stella I Kegel Ball Set?
Before using this device, read the following carefully. There are situations where use is not appropriate without medical advice first.
Do not use this product if you:
- Are currently pregnant.
- Are fewer than 6 weeks postpartum, or have not yet been cleared by your midwife or GP.
- Have a current vaginal or pelvic infection.
- Have recently undergone pelvic or abdominal surgery.
- Have been diagnosed with pelvic organ prolapse (without physiotherapist guidance).
- Have unexplained pelvic pain or discomfort.
Drug and product interactions:
- No known drug interactions — this is a physical device, not a medicine.
- Do not use silicone-based lubricants, as these may degrade the device material. Use only water-based lubricants.
- Do not use alongside other internal vaginal devices simultaneously.
How Should You Use the Stella I Kegel Ball Set?
Using this device correctly is important for both safety and effectiveness. Follow these steps each time:
- Wash your hands thoroughly with soap and warm water before handling the device.
- Clean the kegel ball with a toy-safe cleaner or mild soap and rinse well. Allow to dry.
- Apply a generous amount of water-based lubricant to the ball.
- Find a comfortable position — lying down or squatting can make insertion easier.
- Gently insert the ball into the vaginal canal, leaving the retrieval cord outside the body.
- Stand up and move around gently. Your pelvic floor muscles will naturally engage to hold the ball in place.
- Begin with sessions of 15 minutes and gradually increase to 30 minutes as your strength builds.
- To remove, relax your pelvic floor muscles and gently pull the retrieval cord. Never force removal.
- Clean the device thoroughly after every use and store in the provided pouch.
| Indication | Age Group | Session Duration | Frequency |
|---|---|---|---|
| Pelvic floor strengthening (beginner) | Adult (18+) | 15 minutes | Daily or 5 days per week |
| Pelvic floor maintenance (intermediate) | Adult (18+) | 20–30 minutes | Daily |
| Post-partum recovery (with GP clearance) | Adult (18+) | 15 minutes | As directed by healthcare professional |
What Are the Possible Side Effects of the Stella I Kegel Ball Set?
As with any internal device, some people may experience mild side effects, particularly when starting out. These are usually temporary and resolve on their own. If symptoms persist or worsen, stop use and seek advice from your GP.
Common side effects:
- Mild pelvic discomfort or pressure during initial use.
- Temporary vaginal soreness after longer sessions.
- Mild muscle fatigue in the pelvic floor area.
Less common side effects:
- Increased vaginal discharge (if the device is not cleaned properly between uses).
- Localised irritation if a non-compatible lubricant is used.
- Difficulty removing the device if pelvic floor muscles are very tense — relax, breathe, and try again calmly.
If you experience significant pain, bleeding, or signs of infection (unusual odour, discharge, or fever), discontinue use immediately and contact your GP. You can also find support through our women's health section for related products and guidance.
How Should You Store the Stella I Kegel Ball Set?
- Store in the provided storage pouch after every use.
- Keep in a cool, dry place away from direct sunlight and heat sources.
- Do not store near sharp objects that could damage the surface of the device.
- Keep out of reach of children.
- Do not submerge in boiling water or place in a dishwasher — this may damage the material.
- Check the device for any cracks or damage before each use. Do not use if the surface is compromised.
If you have any concerns about pelvic floor health more broadly, it may also be worth exploring vitamins and supplements that support general musculoskeletal wellbeing, alongside your pelvic floor training routine.

How does a kegel ball set work to strengthen the pelvic floor?
A kegel ball set works by providing gentle internal resistance inside the vaginal canal, which prompts the pelvic floor muscles to contract and hold the ball in place during normal movement. This passive engagement trains the muscles over time, much like low-level resistance training for any other muscle group. The NHS recommends pelvic floor exercises as a first-line approach for stress urinary incontinence and general pelvic health.
How do I use the Stella I Kegel Ball step by step?
Start by washing your hands and cleaning the device thoroughly. Apply a water-based lubricant to the ball and insert it gently into the vaginal canal, leaving the retrieval cord outside the body. Begin with 15-minute sessions of light activity such as walking, and remove the ball by relaxing your pelvic floor and pulling the cord gently.
How long should I use a kegel ball set each day for best results?
Most pelvic health guidance suggests starting with 15 minutes per session and gradually building up to 30 minutes as your pelvic floor strength improves. Daily use is generally recommended, though rest days are important to prevent muscle fatigue. Consistency over several weeks is key — results typically become noticeable after 4–6 weeks of regular use.
Are there any side effects of using a kegel ball set?
Some users experience mild pelvic discomfort or temporary vaginal soreness when they first start using a kegel ball set, particularly if sessions are too long initially. These effects usually resolve quickly with shorter sessions and adequate rest. If you experience persistent pain, unusual discharge, or any signs of infection, stop use immediately and speak to your GP.
Who is the Stella I Kegel Ball Set suitable for?
This product is suitable for adult women who want to strengthen their pelvic floor muscles, including those experiencing mild stress urinary incontinence or those who have been cleared by their GP or midwife following childbirth. It is designed as a beginner-friendly option due to its single-ball, lighter-resistance design. It is not suitable for use during pregnancy or for those with active pelvic infections or recent pelvic surgery.
Can I use a kegel ball set after having a baby?
You should wait until at least 6 weeks postpartum and receive clearance from your midwife or GP before using any internal pelvic floor device after childbirth. The pelvic floor and vaginal tissues need time to heal following delivery, whether vaginal or by caesarean section. Once cleared, a single kegel ball set like the Stella I can be a helpful tool for rebuilding pelvic floor strength gradually.
What lubricant should I use with the Stella I Kegel Ball?
Always use a water-based lubricant with this device. Silicone-based lubricants can degrade the surface material of the ball over time, which may compromise hygiene and safety. Oil-based lubricants are also not recommended for internal devices. You can find compatible personal lubricants in our personal lubricants collection.
What are the alternatives to the Stella I Single Kegel Ball Set?
Alternatives include double kegel ball sets, which offer greater resistance for more experienced users, weighted vaginal cones, or guided pelvic floor physiotherapy with a specialist. Your GP or a women's health physiotherapist can advise on the most appropriate option based on your individual pelvic floor assessment. For related products, browse our condoms and sexual health collection.
How long does it take to see results from using a kegel ball set?
Many people begin to notice improvements in pelvic floor strength and bladder control within 4–6 weeks of consistent daily use. More significant changes — such as reduced leakage episodes or improved muscle tone — may take up to 3 months of regular training. Patience and consistency are essential, as pelvic floor muscles respond to training in the same way as any other skeletal muscle.
How do I clean and maintain the Stella I Kegel Ball?
Clean the device before and after every use using a toy-safe cleaner or mild, unscented soap and warm water. Rinse thoroughly and allow to air dry completely before storing. Never boil the device or place it in a dishwasher, as heat can damage the material. Store it in the provided pouch in a cool, dry place away from direct sunlight.
Is it safe to wear a kegel ball set all day?
No — it is not recommended to wear a kegel ball set for extended periods, particularly when starting out. Sessions of 15–30 minutes are generally considered appropriate, and you should never wear the device overnight or while sleeping. Overuse can lead to pelvic floor muscle fatigue, which is counterproductive to your training goals.
Can using a kegel ball set help with urinary incontinence?
Pelvic floor training, including the use of kegel devices, is recommended by the NHS as a first-line treatment for stress urinary incontinence in women. Regular use of a kegel ball set can help strengthen the muscles that support the bladder, potentially reducing episodes of leakage over time. However, if your incontinence is severe or worsening, you should seek assessment from your GP rather than relying solely on self-managed training.
What is the latest research on kegel ball training for pelvic floor health?
Clinical evidence consistently supports pelvic floor muscle training (PFMT) as an effective intervention for stress urinary incontinence and pelvic organ prolapse prevention. Research published in peer-reviewed journals and endorsed by NICE guidelines confirms that structured PFMT programmes lead to measurable improvements in muscle strength and continence outcomes. Kegel devices such as this one are used as adjuncts to support correct muscle engagement during training.
Can I use a kegel ball set if I have a pelvic organ prolapse?
If you have been diagnosed with pelvic organ prolapse, you should not use any internal vaginal device without first consulting a women's health physiotherapist or your GP. In some cases, pelvic floor training is still recommended, but the type and intensity of exercise must be carefully managed. Self-directed use of a kegel ball set without professional guidance could worsen symptoms in this situation.
How Should You Use the Stella I Kegel Ball Set?
Using the Stella I correctly from the outset will help you get the most from your pelvic floor training and reduce the risk of discomfort. Always clean the device before and after each session, and use only a water-based lubricant to ensure safe insertion and comfortable use.
What Is the Correct Dose of the Stella I Kegel Ball Set?
There is no pharmacological dose for this device, but session duration and frequency are important for safe, effective training. Starting with shorter sessions and building up gradually is the recommended approach for all users, particularly beginners.
When Is the Best Time to Use the Stella I Kegel Ball Set?
Many people find it easiest to incorporate kegel ball training into their daily routine during light activity — for example, while doing household tasks, going for a gentle walk, or during a yoga session. Avoid using the device during high-impact exercise, swimming, or any activity that involves significant straining or bearing down, as this can place excessive pressure on the pelvic floor rather than training it effectively.
Morning sessions work well for many users as the pelvic floor muscles are typically well-rested. However, the most important factor is consistency — choose a time that fits naturally into your day so that you are more likely to maintain the habit long-term.
How Long Can You Use the Stella I Kegel Ball Set For?
This device can be used as part of an ongoing pelvic floor maintenance routine for as long as it remains in good condition and use remains comfortable. Most users see meaningful improvements within 4–12 weeks of consistent training. Once your pelvic floor strength has improved, you may wish to progress to a double kegel ball set with greater resistance, or continue with the Stella I for maintenance purposes.
Never use the device for more than 30 minutes per session, and always take rest days to allow the pelvic floor muscles to recover. If you experience any pain, discomfort, or worsening symptoms at any point, discontinue use and consult your GP or a women's health physiotherapist.
Do not exceed the recommended session duration. If in doubt, speak to your pharmacist.
What Are the Most Common Side Effects of the Stella I Kegel Ball Set?
Most people tolerate this device well, particularly when they start with shorter sessions and build up gradually. That said, some mild side effects are possible, especially during the first few uses as your body adjusts to the sensation of internal resistance.
- Mild pelvic pressure or a feeling of fullness during use.
- Temporary vaginal soreness after sessions, particularly if the session was longer than recommended.
- Mild pelvic floor muscle fatigue, similar to the feeling after any muscle workout.
What Are the Less Common Side Effects of the Stella I Kegel Ball Set?
Less commonly, some users may experience the following. These are usually related to incorrect use, inadequate cleaning, or use of an incompatible lubricant rather than the device itself.
- Localised vaginal irritation or mild redness, often linked to use of a non-water-based lubricant.
- Increased or altered vaginal discharge if the device is not cleaned properly between uses.
- Difficulty removing the device if pelvic floor muscles are very tense — this is usually resolved by relaxing, breathing slowly, and trying again calmly.
- Mild lower abdominal cramping in some users during initial sessions.
What Are the Serious Side Effects of the Stella I Kegel Ball Set?
Serious side effects are uncommon but should be taken seriously if they occur. Stop using the device immediately and seek medical advice if you notice any of the following:
- Significant or worsening pelvic pain during or after use.
- Unusual vaginal discharge with an unpleasant odour — this may indicate infection.
- Vaginal bleeding not associated with your menstrual cycle.
- Fever or systemic symptoms alongside pelvic discomfort.
- Inability to remove the device after relaxing and attempting gentle removal.
What Should You Do If You Experience Side Effects?
For mild side effects such as temporary soreness or muscle fatigue, simply reduce your session length and allow more rest time between uses. Ensure you are using a water-based lubricant and that the device is thoroughly cleaned before each session. If symptoms persist beyond a few days or are causing significant discomfort, stop use and contact your GP.
In the event of a serious side effect — particularly signs of infection, significant pain, or inability to remove the device — seek medical attention promptly. Do not attempt to force removal. A healthcare professional can assist safely if needed.
Can the Stella I Kegel Ball Set Interact With Other Products or Medicines?
This is a physical wellness device and has no known pharmacological interactions with medicines. However, there are some important product compatibility points to be aware of. Do not use silicone-based or oil-based lubricants with this device, as these can degrade the surface material and compromise hygiene. Do not use the device simultaneously with other internal vaginal products. If you are using topical vaginal treatments — such as antifungal creams or hormone pessaries — consult your GP or pharmacist before using this device alongside them.
If you are concerned about any side effects, contact your pharmacist or GP immediately.
