Men have large differences in penis size due to factors such as genetics and acquired development. Some friends with short penis, although there is no sexual function abnormalities, but always, but extremely dissatisfied with their penis size, thus inducing low self-esteem and anxiety, not only affect the quality of sex life, or worse, will cause serious mental illness. The actual number of men who are currently troubled by this “disease” lacks specific statistics, but according to the author’s outpatient work experience, this type of “patient” is indeed quite a few. What is the ideal size of the penis? I’m afraid there is no clear answer to this question, because everyone’s expectations are different. Just as women want to have a full pair of breasts, men want to have an impressive penis size. As a symbol of masculinity, penis size affects many aspects of an individual’s self-confidence, sexual attractiveness, and sexual satisfaction. What is the size of an average man’s penis? Some scholars have investigated the penis size of the nation and found that in the unerected state, the average length of the penis is 7.1cm and the average circumference is 7.8cm; when erect, the average length is 13.0cm and the average circumference is 12.2cm. What factors are associated with penis shortening? Foreign literature reports that male penis size is mainly related to the following factors: 1, genetic factors: the penis, like other organs of the body, its length, circumference and shape are mainly controlled and regulated by genes. 2, development and nutritional status: In general, male penis size and and height are positively related. Individuals who are physically fit and tall have larger external genitalia, and vice versa. But there are exceptions, clinically you can often see some men who are less than 1.60m tall, their penis can be more than 16cm in length when erect. 3, obesity: In the lower abdomen, the pubic symphysis area there is fat accumulation of men, their penis is often small, in addition to obesity factors, but also may be the fault of the occult penis. Due to the usual part of the penis body buried under the skin, visually more appear short penis. As you can imagine, the rich torso and relatively short penis does not meet the modern aesthetic, after marriage often brings a more significant negative impact on sex life. 4, other: such as endocrine disorders, serum androgen levels are insufficient. What are the ways to increase the size of the penis? 1, increase the “capacity” of the penis: increase the length and circumference of the penis (including erection and weak state). At present, the more commonly used methods are autologous fat implants and decellularized allogeneic dermal implants. Some people also place “beads” (a polymer material) under the coronary sulcus, aiming to increase “sexual” interest, and this method is especially popular in Korea and Southeast Asia. 2, penis lengthening surgery: surgery by cutting the penile suspensory ligament below the pubic symphysis, part of the “hidden” in the body of the penis body released, so as to achieve the purpose of lengthening. Generally speaking, the surgery can increase the static length of the penis by 2-3 cm. It should be noted that the amount of the suspensory ligament cut is limited, otherwise it may cause the penis to lose stability and also affect the erection angle of the penis. 3. Androgen level: In addition, the development of the penis involves a series of complex physiological and biochemical processes such as androgen level and androgen receptors. During the developmental period, abundant androgen secretion helps the penis grow bigger and thicker. However, when puberty is over, it is impossible to stimulate the development of the penis by supplementing androgens. 4, hyaluronic acid minimally invasive injection penis enlargement: In recent years, the treatment of short penis through hyaluronic acid injection is favored by many male friends, with a high degree of acceptance. 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 injected into the sarcolemma layer (superficial fascial layer) of the penis can significantly improve the length and circumference of the penis. In the field of male genital surgery, hyaluronic acid can also be used for glans enlargement and premature ejaculation treatment, which is one of the safest, convenient and minimally invasive treatment methods known for penile plastic surgery.
