Some normal men, although their testicular development is normal, but their penis is relatively short, although also able to erect and ejaculate, but often compared with friends of the same sex, feel their penis is small and increased inferiority complex, some will also cause psychosexual abnormalities, and even doubts about their sexual ability, directly affecting the normal performance of sexual function. At present, the proportion of men with short penis in the proportion of men, there is a lack of scientific statistics, but from the point of view of the patients encountered in the clinic work, such patients are indeed quite a few. How thick and long is the ideal penis? I’m afraid there is no – a clear answer to this, everyone’s expectations are different. Just as women want to have a full breast, men want their penis to be big and thick. The size of the penis affects men in many ways. These effects include aspects of self-confidence, sexual attractiveness, and sexual satisfaction. What is the size of the average man’s penis? A survey was done on the penises of Chinese residents and found that the average length without erection was 7.1 centimeters and the circumference was about 7.8 centimeters; the average length with erection was about 13.0 centimeters and the average circumference was 12.2 centimeters. What factors are associated with penile shortening? Foreign literature reports that studies have found that male penis shortage is mainly related to the following factors: 1, genetic factors: penis and other organs of the body, its size and morphological characteristics are subject to the control and influence of genetic genes. 2, development and nutritional status: Generally speaking, adult men are physically fit, tall, their external genitalia, including the penis, scrotum development is also better, the penis may be thicker; conversely, it may be relatively small. But it must be reminded that the size of the penis is not proportional to the height, often seen in some men less than 1.60 meters tall, the penis can reach more than 16 cm when erect. 3, obese:Some small abdomen, pubic symphysis, perineum fat plump prominent men, often the penis is poorly developed, compared to the normal male penis will be relatively short, and the patients themselves visualize their penis difficulties, more think their penis is small. Indeed, compared with the hypertrophy of the body on the short side of the penis in marriage may bring some difficulties and undesirable sexual life. 4, other: such as endocrine disorders, male hormone levels are insufficient, the testicles or scrotum swelling of the penis “retraction”, etc., may cause penis short. Want to increase the penis, what are the ways? 1, increase the “capacity” of the penis: penile corpus cavernosum and urethral corpus cavernosum volume increase, so that the length and diameter of the penis increased (including erect and weak state). The most common method is the implantation of autologous fat, but also the implantation of a mesh stent. Some people also put “beads” (a polymer material) under the coronal groove to increase the “sexual” interest, this method is very popular in Korea. 2, surgery to lengthen the penis: because the penis body is not completely exposed outside the pubic bone, there is a long part of the pubic bone is not exposed, obese people are particularly obvious, medically known as occult penis. The purpose of surgery is to make the unexposed penis exposed again – a small part out, on the purpose of growth. The suspensory ligament of the penis is located in front of the pubic bone and is the connection between the heel of the penis on the dorsal side and the pubic bone. By allowing the penile suspensory ligament to stretch to its maximum extent, penile growth can be achieved effectively. By removing the suspensory ligament of the penis, we can achieve the purpose of lengthening the penis of the patient, and the results of clinical observation so far can lengthen about 2cm after the surgery. The only disadvantage of removing the penile suspensory ligament is that the penis feels less stable, but it does not affect erection and sexual life. 3, In addition, penile erection also involves a series of complex biochemical processes such as testosterone and hormone secretion. Adequate sex hormone secretion helps maximize penis development, erection and longevity, and it is important to maintain normal stability of sex hormones. For small penis associated with low hormone secretion before puberty, the penis can be lengthened and thickened after testosterone supplementation, however, hormone supplementation after puberty has no improvement effect on penis shape. 4, in recent years the prevalence of hyaluronic acid minimally invasive injection for penis enlargement, is also a clinically accepted way. Hyaluronic acid (HA), also known as hyaluronic acid, is a safe filler that can be absorbed and metabolized by the body. Different types of hyaluronic acid are used for different purposes, both for facial hydration injections, facial plastic surgery (nose contouring, chin filling, temporal hollow filling), and orthopedic joint cavity injections to lubricate joints. Hyaluronic acid is widely distributed in all parts of the body and is one of the main matrix components of the epidermis and dermis of human skin. Hyaluronic acid is injected into the sarcolemma (fascial layer) of the penis to thicken and lengthen the penis, which has remarkable clinical effects. In the field of male genital plastic surgery, hyaluronic acid can be used for penile enlargement, penile lengthening, glans enlargement and premature ejaculation treatment, which is the safest procedure among the known penile plastic surgery methods.
