Abstract
ED is defined as the consistent or recurrent inability to
attain and/or maintain an erection sufficient for a satisfactory
sexual intercourse (Caretta and Foresta, 2007).
ED is correlated with age, in Egypt it has 26% prevalence
at the age of 50 years, 49% prevalence at the age of 60 years
and 52% prevalence at the age of 70 years or older (Seyam et
al., 2003). ED can be classified as psychogenic, organic
(vascular, diabetic, drug-induced, traumatic, neurogenic and
hormonal) or mixed psychogenic and organic (Lue, 2000) and
(Burnett, 2006). Vascular insufficiency especially venogenic
ED is probably the most common cause of organic male ED
(Kandeel et al., 2001).
The pelvic floor and perineal muscles play a role in
erection; it is involved in the enhancement of blood flow to the
penis. The ICM facilitates and maintains erection as it
compresses the crus penis and its contraction results in rise of
the ICP well above the systolic pressure (Hassouna, 2001).
The BSM assists in erection as the middle fibers compress the
erectile tissue of the bulb of the penis and the anterior fibers
compress the deep dorsal vein of the penis to prevent the
outflow of blood from an engorged penis thereby maintaining
an erection (Dorey et al., 2004).
The reinforcement of the striated muscles of the penis
achieved through physiotherapy may improve penile erection
(Claes and Baert 1993). Physical therapy interventions are
non-invasive alternative to surgery for the treatment of patients
with venogenic ED and have a strong long-term effect on
erectile ability (Ballard, 1997) and (Van Kampen et al., 2003).
