What is the normal length of a penis?

The penis is a reproductive organ in the male body that cannot be ignored. It also plays an important physiological role in the male body. From a general probability point of view, most men are particularly concerned about the length of the penis, because the length of the penis is generally positively correlated with the male's sexual ability. However, the length of the male penis is mainly related to congenital genetic factors. So how long is the penis of a normal man?

1. How long and how big is the penis considered qualified?

The length of the normal adult penis in my country is 12 cm at most, 3.5 cm at most, and 7.1 cm on average. When erect, the longest is 18 cm, the shortest is 7 cm, and the average is 12.4 cm. The maximum circumference is 11 cm at most, 5.5 cm at most, and the average is 8.1 cm. When erect, the maximum circumference is 14.5 cm, the minimum circumference is 8 cm, and the average is 11.1 cm.

2. Penis size calculation formula

The International Men's Health Organization (MTD) has concluded through nearly 30 years of research:

Normal penis length M=(height T-105)*0.618/3.14 (cm).

The normal penis diameter is D=M/3.14 (cm).

In fact, there are great differences in the size of male penis and race. Generally speaking, Western men's penises are larger, while Oriental men's penises are smaller. However, Oriental men's penises are indeed the hardest, and because they are relatively straight, they can easily satisfy women.

3. How to enlarge a man's penis?

3.1. Increase the "capacity" of the penis: The volume of the penis cavernous body and the bifurcated urethral cavernous body increases, thereby increasing the length and diameter of the penis (including erection and flaccid state). Some people also place "beads" (a kind of polymer material) under the coronal sulcus to increase "sexual" interest.

3.2. Surgery to lengthen the penis: Since the penis body is not completely exposed outside the pubis, there is still a considerable part inside the pubis that is not exposed. Therefore, if a small part of the penis that is not exposed can be exposed, the purpose of lengthening can be achieved. The penis suspensory ligament is located in front of the pubis and is responsible for the connection between the dorsal penis root and the pubis. Extending the penis suspensory ligament to the maximum can effectively lengthen the penis. We achieve the purpose of lengthening the patient's penis by removing the patient's penis suspensory ligament, and the effect is obvious. The only disadvantage of removing the penis suspensory ligament is that the penis feels unstable, but it does not affect erection and sexual life.

Criteria for determining a small penis

1. Short penis: When the penis is flaccid, the length from the pubis to the glans penis is less than 6.5 cm. According to the cases we have treated, some small penises are less than 3 cm long.

2. The testicles are very small, some are only the size of a peanut or a thumb, and are soft in texture. Some men have no testicles at all in the scrotum, which is called cryptorchidism.

3. Secondary sexual characteristics are underdeveloped, with no beard, armpit hair or pubic hair, and also showing female characteristics to varying degrees, such as delicate skin, high-pitched voice, and no Adam's apple.

4. Changes in body shape: obesity, breast development, enlarged buttocks, short stature, etc.

5. Low sexual function or loss of sexual function. If married, they are often unable to complete sexual life.

6. There are often no sperm in semen, but spermatogenic cells can sometimes be seen.

Among the causes of small penis and small testicles, testicular disease and hypothalamic or pituitary insufficiency are the most common.
