Whether it be as a treatment for erectile dysfunction, Peyronie’s disease, rehabilitation post prostate surgery, a dramatic increase in penis length and girth or enhanced sexual pleasure: Here's everything you need to know about Bathmate Hydropumps.

How Does a Bathmate Hydropump Work?

In the Bath or Shower, with the tube filled, the water displaces the air inside the tube. You place your penis inside the tube and hold your Bathmate pressed tightly against your body at the base of your penis. With the comfort ring sealed against your body, no air can get inside creating a vacuum.

When pumping water out, this vacuum pressure, by a natural process, draws blood into your penis to counteract the change in pressure in the tube with minimal pressure on the heart. Increased blood flow to the penis produces an erection that can last up to 30 minutes depending on your level of sexual stimulation.

If used to increase penis size it's necessary to train your penis regularly. Much like when achieving muscle gains, penis gains involve a routine. Bathmate recommends using your hydropump for 3 consecutive sessions of 5 minutes (a total of 15 minutes use) for at least 4-6 months daily. Similarly, as when lifting weights you increase the dumbbell size, as your penis gets larger so too will you have to reinvest in a new Bathmate a size up.

How Do I Use a Bathmate Hydropump?

Regardless of which penis pump from the Bathmate Hydropump product line you decide best suits your goals, the Hydro7, the HydroMax or the HydroExtreme, the way you use each product on your penis follows a similar procedure.

1. Allow yourself to soak in the warm water for five minutes loosening the skin of your penis and scrotum and preventing the risk of your testicles being pulled into the unit. Keep your testicles clear of the Bathmate tube by pulling them back with your free hand when positioning the device for use. Whilst this is not a risk for injury, it would be more than a little uncomfortable.

2. If in the shower, hold your Bathmate upside down under the water stream with the black pip at the top of the device closed. If using your Bathmate in the bath you do not need to close the latch, simply submerge the device underwater.

3. Insert your flaccid penis into the tube pressing your Bathmate tightly against your pubic bone to seal the device. You can angle the Bathmate penis pump upwards or downwards, whichever feels most comfortable.

4. Open the black pip at the top of the device and begin pumping. This will expel water in short jets with each pump. You will feel your penis being sucked into the chamber and your foreskin stretching. The blood vessels will engorge with the change in pressure and you will begin to achieve an erection. The girth of your penis will appear larger due to distortion from the water.

5. Release the vacuum by pressing the valve cap inwards to activate the quick-release mechanism BEFORE removing your penis from the tube.

Pumping in the shower can be more difficult because air may enter reducing suction if your Bathmate is not pushed tightly enough into your pubic bone to seal the device. Once the black pip at the end of the device is opened, begin pumping immediately otherwise water will leak from your Bathmate Hydropump.

If you find air is getting trapped between the comfort ring and the pump you may find it easier to remove the comfort ring before filling and then replace when pumping. Shorter, quicker pumps will increase pressure and slower pumps will give less pressure. To achieve the most gains per workout, it helps to release the vacuum, refill the device and commence pumping two or three times per 15 to 20-minute session.

Are Bathmate Hydropumps Safe To Use?

Bathmate vacuum pumps are noninvasive and without side effects providing they are used sensibly and that you follow the manufacturer’s directions.

Penis injuries can occur and one of the most common ways is by over-pumping. Over-pumping and overuse, too often or in sessions of too long a duration, can damage tissue leading to softer erections.

Dr Christopher Fox, senior lecturer in sexual health at the University of Sydney, says: "Men will over-pump. This can cause damage to the vascular system of the penis. It really needs to be done under guidance - either a sex therapist who understands what they're doing or another pumper who has experience in what they're doing."

The recommendation from experienced users is to ensure the water is warm, massage the penis to warm up the muscles beforehand and start off with a beginner routine of 5 to 10 minutes per day building up to 20-minute sessions.

The exception to this is if you take warfarin, another form of blood-thinning anticoagulant, or have any form of a blood clotting disorder. Under which circumstances Bathmate Hydropumps, nor any form of penis pump, is considered safe for use.

One regularly noted side effect of using a water-based penis pump is fluid retention. This is when the vacuum which has drawn blood flow into the penis has also drawn in fluid. This results in a swelling of the skin covering the penis and some further expansion in girth.

This doesn’t affect penis growth and may cause a doughnut swelling at the base of the penile glans. Depending on the amount of fluid retention this should disappear after 24 hours. The best way to avoid fluid retention is to spread sessions of 15-20 minutes into smaller 4-5 minutes sessions as recommended by Bathmate.

Which is Better, Bathmate Hydropumps or Traditional Air Pumps?

Short answer: Bathmate Hydropumps.

Bathmate pumps capitalize on the natural benefits of warm water which makes the tissues of the penis more supple and further increases natural blood flow by vascular dilation. Warmth also has a conditioning effect on nerves preventing the pain when stretching regularly noted by users of traditional air vacuum pumps.

Applying a hot towel to your penis for several minutes before using a traditional pump mimics this effect. However, if using the pump before play, more time away in prep is, well, more time away. Between having the feature built into your pumping routine and adding in an extra step, it's clear which is the more convenient option.

With air pumps, it's necessary to use lube to keep the penis soft when stretching which is eliminated with the use of water. Water is also denser than air and blankets the penis with a more even distribution. Side effects of air pumps include bruising caused by areas of excess pressure on the penis from uneven air distribution. This can cause subcutaneous bleeding and tiny red spots on the penis.

Traditional pumps have a gauge showing pressure level. If you go too high there's no way to release pressure and air will continue to compress inside the tube. It’s up to you to know how much pressure is enough pressure and don’t surpass it. Do you know how much air pressure is the right amount of air pressure?

Bathmate Hydropumps have a one-finger valve that will immediately release the pressure if you over pump. Bathmate's design restricts the water entering the tube and therefore pressure from the start allowing you to pump for max gains without damage.
