A penis pump is a cylinder that is fitted over the penis, with a manual or motorized pump to create suction. As the apparatus creates a partial vacuum around the penis, blood is drawn into the penis, helping it to become engorged. As vacuum increases, the difference between the inner blood-pressure and the pump pressure increases as well; excessive pressure causes vascular damage rather than a harder penis.
They usually described in this context as vacuum pumps, have use in conventional alleviation of impotence. The pump itself is essentially as described above, although often made to higher standards of quality with a much higher price, and arrangements for distribution by suppliers of medical equipment. The purpose is not to cure the condition, but to attain an erection by mechanical and hydrodynamical means even if there is nerve and vascular damage preventing a full natural erection; once the penis is erect, a compression ring is slid on to maintain the erection which will otherwise subside immediately.
A flexible compression ring (or sometimes more than one), commonly called cock rings when used recreationally, must be used. It is fitted on the open end of the cylinder, then an erection is created by pumping. Then the ring is pushed by hand onto the base of the erect penis before releasing the vacuum. This restricts blood flow out of the now erect penis, enabling the erection to be held even in the presence of problems of the vascular or nervous system which would otherwise lead to immediate loss of erection. In the best circumstances erections can be maintained for a considerable time, but manufacturers' literature recommends that, for safety, rings should be removed after no more than 30 minutes. Very prolonged use (hours) will cause permanent harm.
A personal lubricant of a type not harmful to the ring material is used, primarily to make a good seal at the base of the pump to prevent air leakage, in the same way as vacuum grease is used with a laboratory vacuum pump,. It also makes it easier to slide the ring off the cylinder, and later to remove the ring.
Pumping must be done very carefully to avoid serious injury: over-enthusiastic pumping can burst blood vessels and form blisters. In some cases the testicles can be unexpectedly pulled into the cylinder, causing discomfort, pain, and possibly injury.[citation needed] It is also believed that the rim of the cylinder can cut into the skin and over time cause damage to the ligaments surrounding the penis. Impatiently pumping without reading explanatory material can produce too much suction (any pressure lower than 10 torr/1,333 Pa)[citation needed] and cause permanent and irreparable injury. Attempts at using vacuum cleaner units for this purpose have resulted in extremely severe injuries because the suction is far too powerful.
Pumps used with rings are virtually always effective, as they operate by a simple mechanical process, in cases of ED, even when pharmaceutical methods fail. They may nonetheless be found unsatisfactory due to the inconvenience and similar factors.
The effectiveness of penis pumps for permanent penis enlargement was examined by Kazem, Hosseini and Alizadeh. They studied 37 men with penis length less than 10 cm and found no significant change in penile length after using pumps for six months, although the follow-up have found 30% satisfaction with the method.
A 31-patient study conducted by the Department of Urology at St Peter's Hospitals and the Institute of Urology in London investigating the usefulness of pumps to correct the penile curvature associated with Peyronie's disease found that "There was a clinically and statistically significant improvement in penile length, angle of curvature and pain after 12 weeks of using the vacuum pump". In this study, subjects with Peyronie's undertook two ten-minute pumping sessions per day for twelve weeks. The additional penis length was an unexpected side effect and not an intended aim of the study, but large enough to be statistically significant.
Stretching
Stretching consists of attaching a penis stretcher or "extender" device to the penis for set periods of time. The device exerts a constant traction on the penis, which, in theory, lengthens and widens the penis. The traction supposedly causes the cells in the penis to divide and expand. In 2002 a study published in the International Journal of Impotence Research concluded that penis extender devices are effective at elongating the penis and furthermore increases the penis length in correlation with the amount of time the device is worn. A study conducted at the University of Turin and published in 2009 in the British Journal of Urology showed similar results, using a penile extender exerting a continuous and gradually increasing traction force on the penis. The device consists of a plastic ring, where the penis is introduced, with two dynamic metallic rods which produce the traction. After using the device at least four hours daily for six months, the mean gain in length in flaccid state was 2.3 cm, with significantly improved erectile function scores and treatment satisfaction scores of "acceptable" to "good improvement" in all items, except for penile girth, where there was no significant measurable or subjective changes. However, the study population only included patients with inadequate penile dimensions, so it remains uncertain whether the same effects would occur on all subjects.
Jelqing
Jelqing and "jikok" is a penis enlargement method intended to make the penis larger by "exercising" tissues in the penis, with the goal of permanently increasing the maximum erect size of the penis. This technique, also called "milking", involves wrapping the thumb and index finger around the penis while semi-erect and repeatedly drawing them away from one's body to force blood into the glans, thus encouraging more vascularity in the corpus cavernosum and associated tissues.
There are many products (tools, instructions, etc.) that one can buy; however, much of what they offer (instructions) is available on forums and free websites, however this information is usually not composed or supported by medical professionals, thus can be inaccurate.
Jelqing is typically preceded by a warm-up with a hot compress on the genitals, and concluded the same way. The reasoning behind the 'warm-up' mimics the normal operation of the biological processes of the penis during the four stages of arousal. The third stage is heat.
Jelqing may lead to damage of the penile tissues and may also result in permanent scarring and permanent discoloration of the penis[citation needed], amongst other things there is a moderate risk of damage to and rupture of the penile veins and capillaries[citation needed]. One should always take caution when performing this exercise.
Clamping
Clamping is a risky and dangerous technique. The goal of clamping is to increase the girth of the penis. This enlargement technique uses a constricting device, such as a shoe string, cable clamp, or a tight cock ring. The device is firmly tied, clamped, or put, respectively, on the base of the erect penis while "edging" (extended masturbation) with a firmly erect penis. Use of a metal cock ring is not advised because trapped blood engorging the penis can make it impossible to remove without amputation or emergency intervention such as sawing the ring off. Clamping is considered extremely dangerous by both practitioners and the medical community as it can cause permanent catastrophic damage to the penis.
Hanging
Hanging is perhaps the oldest self-applied method of penis enlargement, with evidence suggesting it was practiced by certain African tribes as much as 2,000 years ago. Weight hanging consists of attaching a device (usually a rope or a strap) that grips the glans or just behind the glans and allows a weight to be suspended for a specific amount of time. Then a conscious effort is made to exercise the penis by raising the weight in repetitions (lasting no more than 5 to 10 minutes at a time) starting with the smallest and lightest weight 1/16 pound to the heaviest usually 1/4 pound or more, to increase the strength and stamina as well as elongation of the penis.
Weight hanging, however, can also carry serious risks, which include nerve damage, chronic pain, scarring and impotence. The idea behind weight hanging is to stretch the tunica albuginea and other various tissues of the penis. The general effect is to elongate the penis, although widening can also occur, commonly at the base of the penis.
Hanging carries additional health risks due to the restriction of blood flow to the glans, including possible erectile dysfunction. Many tribal practitioners of weight hanging are impotent[citation needed], although urination is unaffected.
The procedures (sometimes euphemistically referred to as male enhancement procedures in spam email and television advertisements) are techniques alleged to make the human penis increase in girth, length, or hardness. 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 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 to 6 inches).
A related method involves injection of silicone, PMMA, and other materials into the penis and scrotum, to achieve penis girth enlargement. The results of the study into penis 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, and some have even shrunk, 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 donated 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".
