How to calculate the length formula for boys' younger brothers?
The length of penis is closely related to race and heredity. Western Europeans have relatively long penises, while eastern Asians have relatively short penises. This formula is aimed at the international average of men. For China people, the average length of penis after erection is 12 cm, and it will be normal if it exceeds 8 cm, and it will not affect normal sexual function.
The calculation method of penis length, there are two main ways to measure penis length, one is erectile state, the other is non-erectile state. There are two methods for measuring the diameter of the non-erect state length, as follows:
First, at the ulnar junction, that is, the side of the penis close to the stomach, the length from the root of the penis to the head end, that is, the tip of the glans penis, is measured without pressing the stomach with a ruler.
Second, at the root of scrotum, measure the included angle between scrotum and penis again. Theoretically, this part on the ventral side should be a little longer.
Another key issue is the length of the penis in an erect state. In the state of erection, it is still measured. Theoretically, the penis length is normal when the erection length is greater than 10cm, while the penis length is less than 10cm, which is generally called penile shortness in diagnosis. It is necessary to lengthen the penis or check why it causes penile shortness.
The length of penis
The size, length and thickness of penis have a certain range, and there is no fixed gold standard. There are obvious individual differences in the size of penis. There are many factors that can affect the size of penis, including some people who have more abdominal fat and cryptorchidism. The weather is too cold, which makes them look smaller when they swell with heat and contract with cold, but it has nothing to do with height.
In our country, the length of male penis is between 6-9cm and the circumference of penis is between 7-9cm, but this is not the gold standard to evaluate whether the penis size is normal or not, and it is not certain that the penis within this range is abnormal. The size of the penis has no practical effect on sexual life unless it is too big or too small.
