It’s important to note that using a penis pump does not treat any underlying causes of erectile dysfunction, says
Dr. James Elist, MD—a urologist in private practice and inventor of
Penuma, the first FDA-cleared penile implant.
According to Elist, the effects of using a penis pump can last for up to 30 minutes. This can range, though, depending on your overall health and level of arousal.

Are penis pumps safe?According to Pearlman and Elist, penis pumps are generally considered safe for most men to use. However, keep in mind that using a penis pump
can worsen existing penile conditions, like priapism.
In some cases, penis pumps can
cause blood clots, scarring, and other damage—but don’t worry, these issues are rare and typically only happen with improper use. One
older study of 1,500 penis pump users showed that not a single participant reported any serious adverse effects.
Here are some precautions Pearlman and Elist advise taking to minimize the risk of any negative side effects:
• Consult with your doctor to ensure that you’re a good candidate for a penis pump.
• Following the manufacturer's instructions carefully.
• Consider applying a warm compress before sexual activity as the penis pump can make the penis colder to touch.
• Follow a pattern of pumping three times and then pausing for 10 seconds until you achieve a solid erection. If you pump too fast or too much, Pearlman warns that you may experience pain, bruising, and skin discoloration.
You’ll likely feel some pressure or a stretch in your penis, Pearlman explains—but you should never be in pain using a penis pump. If you do feel extreme discomfort or pain, stop using it immediately.
How to use a penis pumpUsing a penis pump for the first time may feel intimidating—but they’re actually pretty easy to operate.
Just follow these steps, per Pearlman and Elist’s advice:
1. Trim public hair around the base of your penis. This isn’t a requirement, but it’s well worth the extra step—it allows you to get a closer seal, and prevents your pubic hair from getting caught in the ring (ouch).
2. Apply a water-based lubricant on the shaft and base of the penis. Lube reduces friction to prevent irritation, and also makes it easier to slip the pump off after you use it.
3. Insert your penis into the plastic tube—you may need to reposition your scrotum here until it’s comfortable. Then, use the attached hand pump or electric pump attached to suction out the air and create a vacuum effect. Keep in mind: it’s a marathon, not a race—so build the pressure slowly.
4. Most people get an erection in
30 seconds to seven minutes. Once you’re hard, hold the base of your penis firmly with one hand while you remove the tube, and then slip the constriction ring around the base of the penis to keep it hard. (If you’re using the penis pumps as part of a rehabilitation program rather than for sexual activity, Pearlman recommends skipping this step.)
5. To reduce the risk of side effects, never use the pump or constriction ring for longer than 30 minutes.
As a general rule, Pearlman and Elist say penis pumps are safe for daily use. Still, they advise checking in with your doctor to get more personalized guidance on the appropriate frequency for you.
