Inherent curvature of the penis (penile deviation)
It is common that an erection is not absolutely straight and is characterised by a mild curvature.
A slight penile curvature does not limit ability to engage in sexual intercourse. However, there may be a desire for straightening due to aesthetic or psychological reasons, particularly regarding downward curvatures or curvatures to one side.
Erectile angles of curvature of more than approx. 30 degrees (e.g. Peyronie’s Condition) can make introitus (vaginal penetration) more difficult and may cause discomfort for the partner. Even stronger curvatures (Peyronies disease) may render the penetration close to impossible (buckling effect or simply an awkward shape to shape fit issue). Such a pronounced penile deviation can be corrected surgically by removing a tolerable loss of penile tissue substance of the longer non-fibrosed side (so-called Nesbit technique) – see below for more information on surgical approach solutions..
Regarding a modification of the penile tissue named after its discoverer (Francois de la Peyronie), Peyronie’s Disease – also known as Induratio penis plastica, IPP) is a strong curvature or a strong angularity of up to 90 degrees (or more) that frequently occurs with the consequence of painful erections (during the ACTIVE inflammatory phase), erectile dysfunction (secondary to dorsal impedance of penile circulation or reduced sexual activity), or loss of sensitivity of the glans (dorsal impedance of nerve conduction). The penis may also shorten significantly in light of the curvature, or more so if there is an associated erectile dysfunction (dis-use atrophy).
Peyronies disease is a diagnostically palpable induration (so-called "plaque"), presumably a consequence of an inflammation between the cavernous bodies organ and their adventitia (tunica). Peyronie’s occurs in people between 20 and 80 years of age and must not be confused with an inherited (congenital) penile curvature which men are born with – and is relatively common in minor angulations.
The penile extenders PeniMaster and PeniMaster PRO can generally help in reducing curvatures of the penis from peyronie.
The application of PeniMaster PRO at the beginning of Peyronies disease can counteract a progressive penis curvature. Even before a penis is straightened by an operation within the framework of Peyronies disease or inherited penile deviation, wearing an expander may already result in an established curvature being straightened so that less healthy tissue must be removed from the member for compensation purposes and the penile shortening may be smaller. An extender may also be used to counteract the retractive scar-healing procedure and therefore help establishing the operation result also after peyronie operation.
Regarding a so-called acquired penile curvature (Peyronie disease) tissue lumps (scar tissue or Peyronie’s Plagues) form on one side of the penis (semi-circle) while the other side is no longer able to erect to the full extent. The surgeon will cut out a wedge of tissue from the side that has the longer normal length (triangle) and will suture the sides together afterwards. The penis will be straighter afterwards, but it will also be significantly shorter (potentially several centimetres in erection) after a Nesbitt’s operation.
