Penis Enlargement Methods–Surgery methods.

Penis enlargement procedures (sometimes euphemistically referred to as male enhancement procedures in spam email and television advertisements) are techniques alleged to make the human penis larger in width, length, or both. Often, in the course of advertising fraudulent products, the distinction between temporary enlargement, i.e. erection, and permanent enlargement, is deliberately muddied.
Procedures range from manual exercises to stretching devices and surgical procedures, with reports of successes and failures around the world. While some of these are known to be outright hoaxes, other techniques seem to have some measure of success.
Very little legitimate scientific research has been done on penile enlargement, so any claims of significant and permanent enlargement can be biased or anecdotal. Conversely, there is an element of risk to most of the procedures, with negative outcomes ranging from the tearing of skin and scarring, to permanent loss of sexual function. Due to the speculative nature of any hope for "improvement" and the many known cases of permanent injury involved in this endeavor, many medical professionals are skeptical of the subject.
At present there is no consensus in the scientific community of any non-surgical technique that permanently increases either the thickness or length of the erect penis that already falls into the normal range (4.5 to 7 inches).
Surgical techniques used for penis lengthening (enhancement phalloplasty) and penis widening (girth enhancement) have been in the urologic literature for many years. In a study conducted at St. Peter's Andrology Centre and Institute of Urology in London, it was determined that most patients who underwent penis-lengthening surgery were unsatisfied with the results.
Penis enlargement (girth) surgery
A related method involves injection of silicone, PMMA, and other materials into the penis and scrotum, to achieve girth enlargement. The results of the study into penile augmentation surgery mentioned above confirm that surgical techniques used to thicken the penis are far more effective than those designed to increase penile length. In the research sample of men studied, flaccid circumference following the above procedure had increased from an average of 3.1 inches to an average of 4.1 inches, whilst erect penile circumference increased from an average of 4.1 inches before surgery to 4.8 inches after surgery,[citation needed] but is effectively irreversible and may have side effects including loss of sensation, inability to perform penetrative intercourse, scarring, and deformation.
In 2006 the journal of European Urology reported autologous tissue engineering using biodegradable scaffolds as beneficial not only for men with penile dysmorphic disorder and for correcting severe penile shaft deformity after lipofilling but also an advanced, well-proven therapeutic approach for penile girth enhancement with remarkable safety, reproducibility, superior cosmetic results, low morbidity, and low incidence of post-operative complications. Unlike the high level of dissatisfaction with lengthening cited in the opening paragraph of this article, 81% of patients scored the results of autologous tissue engineering as "excellent" and "very good" with most experiencing a 4 cm (1.6 inches) permanent flaccid girth gain. Unlike the injection or implantation of foreign substances into the penis such as AlloDerm, silicone, and other substances, tissue culture leaves no residual foreign tissue around the penis after scaffold reabsorption by the body.
Although AlloDerm (treated cadaver flesh) is currently being used by some plastic surgeons, its manufacturer does not recommend it for penis enlargement phalloplasty. The U.S. Food and Drug Administration (FDA) regulates its use and has specifically not approved AlloDerm as a "void filler" nor for "cosmetic augmentation". The manufacturer warns phalloplasty surgeons that it is: "important to clarify ... cosmetic augmentation phalloplasty does not fall within approved procedures for which LifeCell can promote AlloDerm".
Penis enlargement (length) surgery
Approximately one-third to one-half of the penis is inside the body, and is internally attached to the undersurface of the pubic bone. Penis lengthening involves the release of the fundiform ligament and the suspensory ligament that attaches the two erectile bodies to the pubic bone (ligamentolysis). The suspensory ligament makes the penis arch under the pubic bone. Release of this ligament allows the penis to protrude on a straighter path, further outward to give a longer physical appearance. With the penis on stretch, the ligament is divided close to the pubic bone until all midline attachments have been freed. Once these ligaments have been cut, part of the penile shaft (usually held within the body) drops forward and extends out, enlarging the penis by 2–3 cm (0.78–1.18 in.). After surgery, part of the postoperative treatment includes stretching of the penis to prevent the severed suspensory ligament from healing shorter than it was previously. The article "Penile Suspensory Ligament Division for Penile Augmentation: Indications and Results" discussed the subject. According to Nim Christopher, a urologist at St. Peter's Andrology Center in London, among men who have had the surgery, "the dissatisfaction rate was in excess of 70 percent".
Real penile lengthening (i.e., lengthening of corporal bodies vs. ligamentolysis) is not a routine or safe procedure because of high risk of losing the ability to have an erection. It can only safely be done during implantation of penile prostheses in patients with erectile dysfunction or Peyronie's disease. The world's leading urologists specializing in the field of penis enlargement surgery use only ligamentolysis, liposuction of the pubic area, and skin redistribution. They state clearly that surgeons can only expose the penis more outside the body with especially visible results in obese patients and ones with different deformities of penile skin where the penis is layered.

Inflatable implants

A further method is to replace the two corpora cavernosa with inflatable penile implants. This is performed primarily as a therapeutic surgery for men suffering from complete impotence; an implanted pump in the groin or scrotum can be manipulated by hand to fill these cylinders from an implanted reservoir in order to achieve an erection. The replacement cylinders are normally sized to be direct replacements for the corpus cavernosa, but larger ones can be implanted.
One advantage to this surgery is that an erection can be created whenever desired, for as long as is desired and as firm as desired. However, this surgical procedure can never be reversed.
Beside surgery, there are some other penis enlargement methods you can do by your seft are: cosmetic, pills, penis pump, stretching, jelqing, clamping or hanging.
