The external vacuum device consists of a clear plastic cylinder,
a vacuum pump and a tension ring. The cylinder is placed
over the penis and the vacuum pump draws blood into the
penis. A tension ring placed around the base of the penis,
traps blood inside the penis and maintains the erection.

At first some men may develop reddish pinpoint dots (petechiae)
or bruising (ecchymosis) on the penis from the negative
pressure of the vacuum pump.
It is a non invasive technique (is used on the body not
in the body). An erection may be obtained within a few minutes.
Some men find the vacuum device awkward to use. The penis
is cooler to the touch because fresh blood is not circulating
through the penis. The tension ring must be removed within
30 minutes (after several minutes the process may be repeated).
Ejaculation may be difficult. |
