Penis Pump vs Vacuum Erection Device - What's the difference?

‘Penis Pump’ is the generic name for the ‘sex toy’ intended version of trouser vacuum technology.

Think: Austin Power. Think: misleading adverts on the side of free pornographic websites. Think: novelty purposes only.

You tend to find Penis pumps in physical and online sex shops. They consist of a plastic cylinder, usually 2 inch + diameter, with a hose attachment for sucking air out to create the vacuum with a bulb or trigger mechanism (if you buy a penis pump, always check it has an air release valve for safety).

The penis pump is intended for men who already have an erection or semi-erection. The penis pump draws more blood in for a little bit more oomph.

Does using a penis pump regularly cause permanent lengthening? There is no hard evidence for this (sorry, puns are always intended).

However, straight after pumping the pumper will likely enjoy more fullness, girth and length, especially when coupled with a constriction ring (sex shop translation: ‘cock ring’).

Vacuum erection devices on the other hand use the same basic technology, but with a different intention and therefore subtle but important design differences.

Vacuum Constriction/Erection devices, or Vacuum Pumps, refer to medical-grade standard pumps. They are designed with chronic erectile dysfunction in mind. ie - you feel aroused but with no response downstairs. This can be a common side effect of many cancer treatments, diabetes, cardiovascular conditions, or the cause may be hormonal or psychological.

The device is therefore designed so that men can use it from a flaccid state, and can maintain the erection created in the cylinder afterwards with proper constriction technology (like the five ring system by Vacurect - see image above).

Subtle differences between a medical-grade vs a commercial penis pump include :

  • medical grade pumps tend to come with a more robust constriction system designed to keep blood in the penis (sex shop ‘cock rings’ tend to be too loose for this purpose).

  • some medical grade pumps have smaller, tapered openings to avoid testicle suck-up when pumping from flaccid (an awfully painful experience).

  • the pressure within the cylinder is usually stronger with a medical-grade device so it takes less time to move blood into the penis from flaccid.

  • the system for removing air from the cylinder is usually a lot easier on the hands

In conclusion : If you achieve erections spontaneously or using medical aids like pills or injections and you just want to add a bit more oomf factor, then you may want to try a commercial penis pump. They are usually cheaper and available at sex shops. However, if you have chronic ED (no spontaneous erections) and you want the device for regular rehab and for the bedroom (or you are not getting consistent results using pills or injections) then I recommend investing in a medical grade device.
