What is Bathmate?

Once a small start-up, Bathmate now dominates the penis pump industry. In 2004, innovator John Edwin Oakes crafted the first hydro pump to aid his friend – an injured athlete unable to achieve erections post-spinal injury. Dissatisfied with existing pumps, John applied his engineering skills to develop a revolutionary solution. By utilizing water for vacuum pressure, he revolutionized ED treatment with the world’s first water penis pump. Penis pumps have a success rate of up to 90% in helping men with erectile dysfunction achieve erections.1

Bathmate dominates the penis pump industry today

Just like the original invention, Bathmate pumps utilize water to initiate a vacuum seal surrounding the penis. When placed over the flaccid penis filled with water, you can pump the device against your pelvis, expelling excess water via a unique valve. This forms even pressure inside the pump, drawing blood into the shaft comfortably and evenly. The result? Potentially enhanced erection size and quality without discomfort.2 Established in 2006, Bathmate launched its first product – which we now call the Hydro7. The Bathmate Hercules quickly became popular and grew into a variety of offerings with added features.

Primary characteristics of Bathmate Penis Pumps

Bathmates are not just another gimmick. They have been meticulously crafted with innovative design features to ensure the utmost effectiveness, comfort, and ease of use. Let’s explore these game-changing design elements.

What The Experts Said

Researching products online can be tricky. It’s tough to know whether the info comes from real users. To ensure you’re getting the facts, we consulted with Thomas M. Buckley, MD, an Associate Professor of Urology and our expert medical reviewer on the Bodyfreedom advisory board, for an honest opinion on the brand and its products:

Bathmate stands out as a top brand in the field, constantly innovating with new technology. By switching the medum of air to water, they eliminate uneven pressure risks. The patented PIP valve ensures even water distribution for controlled pressure. While lacking a pressure gauge, these pumps are best suited for experienced users. Despite a higher price tag, their products are worth the investment. If budget is an issue, there are alternative air pumps available with similar performance and quality.

Advantages of Using Bathmate Pumps

With each body being unique, penis enhancement through pumps is a personalized journey. Beware of false promises claiming identical results to others. Here are some common benefits users have experienced:

Enhanced Erections

Did you know that the muscles in your penis relax to allow blood flow into the ‘corpora cavernosa’ when an erection occurs? This sponge-like tissue can make your penis harder, longer, and thicker for intercourse. Erectile dysfunction can prevent full engorgement of the penis with blood, leading to a softer or weaker erection. Upto 77% of users are happy with the outcome of treating ED.4

Surprisingly, penis muscles relax when you become erect.

Water pumps address this issue with a two-pronged approach. By applying uniform pressure, they enhance blood flow to the penis for stronger erections. Warm water promotes muscle relaxation, further increasing blood flow. This unique method leads to superior results compared to using no pump or an air-based pump that doesn’t relax muscles.

Effects ranging from temporary to potentially permanent in both girth and length

Beware of false promises about penis pumps as permanent extenders, but some users do see gains. A pump is meant to increase blood flow for a fuller erection.5 With consistent use, you may notice a bigger and additionally satisfying result than usual.

Beware of promises that any penis pump ensures permanent extension. Stay skeptical

Speaking of permanent enlargement using hydro pumps is challenging due to the lack of scientific studies. Therefore, any claims of permanent gains should be taken with caution. However, don’t dismiss it entirely. Anxiety about penis length can affect sexual function, leading to softer erections. With a Bathmate, this anxiety may decrease, potentially resulting in a fuller and more prepared penis for action.

Heightened penile sensitivity.

Enhancing penis acuity is crucial for a satisfying sexual experience. A lack of sensitivity can lead to delayed or nonexistent erections and orgasms. The Bathmate is a valuable tool for increasing sensitivity, resulting in more powerful erections. Various factors such as stress, anxiety, cycling, and diet can contribute to decreased circulation around the penis, leading to reduced erection quality. A flimsier erection denotes less passionate sensations during sexual activity.

Heightened sensitivity in the penis is crucial for maximizing pleasure during sexual activities

The warm water relaxes muscles, boosting blood flow for optimal performance. Its powerful negative pressure draws blood where it’s needed most, priming nerve endings for peak action. Get ready to experience a whole new level of satisfaction.

How to use the Bathmate Pump: Pro Tips for Optimal Results
Shave or trim pubic hair
Ensuring a tight seal between your skin and the base of your Bathmate can be challenging with excessive body hair. Consider trimming to a 1-2 guard or removing hair completely for easier sealing.
Prepare the pump
Always ensure your pump is clean before use. To guarantee cleanliness, store it sanitarily or give it a quick clean with soap to eliminate any lingering bacteria.
Locate the perfect spot
Fill your Bathmate with water and maximize its effectiveness by pumping in the bathtub or shower. If you’re short on time, using it elsewhere is an option – just keep a towel handy to soak any spills.
Make sure to warm up
To maximize blood flow, consider warming up your penis and surrounding muscles with a hot bath or shower before pumping. This can enhance results by ensuring your muscles are primed for success.
Enter into it
Get ready to slip the pump onto your penis. Fill the cylinder with warm water, then insert your penis. For best results, don’t use the pump when completely flaccid – aim for some level of erection before starting. To get things going, try fantasizing or light masturbation. If you’re comfortable, consider involving a partner for added stimulation.
Create a water-tight seal
Insert your penis into the pump and push the base against your body. Excess water will be discharged via the top valve as you accommodate the bellows towards your groin until it seals. With practice, this process becomes more effortless each time.
Begin slowly Pumping
In a pumping motion push the pump against your groin until you can feel a suction seal around the base of the pump and your penis, ensuring pressure without discomfort. Adjust as needed and play with the suction until it feels right for you. Keep track of the number of pumps for future reference. The sensation of increased blood flow may be unusual, but if you’re not in pain, it’s doing its job effectively.
Pay close attention
For optimal results, our experts advise employing the pump in a few short 5-minute sessions. Release the pressure and pump again 2, 3, or 4 times to achieve your desired goals. Keep a close eye on your penis during this process – a slight flush is normal, but if it appears too discolored, injured, bruised, or swollen, reduce the pressure for next time.
Release the pressure
Once you’ve reached your desired time, simply press the top valve to release the pump. This gentle action gradually relieves pressure, preserving your gains.

What is the optimal timing for maximizing your gains?

As per the user guide, pump for a total of 10-15 minutes daily.6 Optimal results come from pumping in 5-minute increments.

Bathmate, a company of significant size, has thoroughly researched this product to ensure it is safe and well-suited for your body’s tolerance levels.

Each body is unique, so take days off between pumping sessions if you feel any irritation. Gradually increase the time as you become accustomed to the pump. Results and techniques will differ as per individual anatomy, so begin slowly and find a ritual that suits you best.

Can you use a Bathmate before sex?

Achieve a strong erection with its help, making it an ideal pre-sex preparation tool. Find a routine that suits you best for optimal results. Enhance your pumping experience by adding a cock-ring to the mix. Experiment with different types to find one that is comfortable and works well with your routine but don’t use it for longer than 30 minutes.7

Prepare for mind-blowing sex with the ultimate tool to achieve a powerful erection.

Wondering what a routine should entail? Begin by achieving a semi-erection, possibly with your partner’s assistance. Pump to the greatest comfortable tension as instructed above for 3-5 minutes to attain an erection. Discharge the pressure from the pump and promptly place the ring on.

Exploiting the Bathmate to Promote Growth

Are you ready to boost your sexual performance and health for long-lasting gains? To achieve this, you must approach a regular pumping regimen differently than just preparing for sex. Remember, any gains will come from a pumping marathon, not a sprint. Don’t overlook this crucial point!

Take your time and stay focused on your goals, avoiding the temptation of seeking quick fixes or immediate results.

Create a daily routine. Start with 2-3 short sessions. Consider adding massage or jelqing techniques for added benefits. Jelqing’s effectiveness varies depending on the person, but it can help warm up the area and improve blood flow for healthier erections.8 Results won’t happen overnight, so be patient. Stick to a plan that works for you and see progress after weeks or even months of consistency.

How to Clean Your Bathmate
Mastering the use of it is crucial, but maintaining its cleanliness is equally important. These steps not only eliminate bacteria but also extend the lifespan of your pump. Despite the detailed instructions, cleaning will only require 2-3 minutes plus drying time.
Take apart
Dismantle your pump meticulously, taking out the valve and any removable parts.
Rinse with water
After each use, flush the pump with warm water.
Use a Sanitizing Product
Clean your pump thoroughly by mixing warm water with soap or using a specialized cleaning fluid. Gently scrub both the inside and outside surfaces, focusing on areas that touch the skin directly. For tough spots, scrub using a brush to guarantee a deep clean.
Valve Maintenance
Be vigilant with the valve, making sure it is free of any remnants or soap deposition.
Always ensure a thorough rinse
Once the solution has been used for cleaning, make sure to thoroughly flush the pump with water to eliminate any leftover soap residue.
Leave to Air Dry
Dry the pump thoroughly by shaking off any surplus water and allowing it to air dry thoroughly. Place it in a well-ventilated place, away from direct sunlight to prevent damage to the material.
Put it back together
After ensuring all components are thoroughly dried, meticulously reassemble the pump.
Proper storage is crucial
Keep your Bathmate stored in a dry, cool area to protect it from direct sunlight.
Frequent Maintenance
Regularly inspect your pump, focusing on the valve for any indications of wear or deterioration. Bathmates are expertly crafted, ensuring minimal issues; however, if you do notice any problems, cease using the pump immediately.
