Regarding the standard size of the prostate, it is generally recognized in the current medical community that "40 × thirty × 20mm. Therefore, this value naturally becomes one of the important diagnostic bases for prostate diseases.
Next, let's take a look at the actual size of the prostate, approximately or less than the standard size, which diseases can be used for diagnosis.
1. The actual size of the prostate is greater than 40 × thirty × 20mm』
The actual size of the prostate is greater than 40 × thirty × "20mm" can generally preliminarily determine the presence of prostatitis, prostatic hyperplasia, prostate cysts, and prostate cancer.
According to the descending order of clinical incidence, the approximate order is "prostate hyperplasia → prostatitis → prostate cyst → prostate cancer". According to the descending order of increase amplitude, the approximate order is "prostate cancer → prostate hyperplasia → prostate cyst → prostatitis". According to the descending order of the possibility of enlargement, the approximate order is "prostate hyperplasia → prostate cancer → prostate cyst → prostatitis".
2. The actual size of the prostate is less than 40 × thirty × 20mm』。
The actual size of the prostate is less than 40 × thirty × "20mm" can generally preliminarily determine the presence of prostate atrophy, prostate calcification, and prostatitis.
According to the descending order of clinical incidence, the approximate order is "prostatitis → prostate calcification → prostate atrophy". According to the descending order of reduction, the approximate order is "prostate atrophy → prostate calcification → prostatitis". According to the descending order of reduction probability, the approximate order is "prostate atrophy → prostate calcification → prostatitis".
However, the standard size of the prostate cannot be applied mechanically
Prostate gland × thirty × Although the standard size of "20mm" has been widely recognized by the medical profession, this standard is only a relative standard, and in actual clinical practice, it is not allowed to use it to carry a rigid condom. As for the reasons, there are two main reasons:
1. Prostate size, influenced by race.
Compared to the yellow race, the black and white races have very tall stature and well-developed external genitalia (including the penis, testicles, etc.). In fact, in addition to their stature and external genitalia, black and white people often have a slightly larger prostate size than yellow people.
It is understood that the prostate has the function of secreting hormones, stimulating transformation, and supplying the whole body. These hormones secreted and transformed by the prostate have a very important function, which is to promote the development of bones and sexual organs, and maintain the secondary sexual characteristics of men.
It can be imagined that black and white people, who can grow such tall stature and well-developed external genitalia, will not have too low requirements for prostate secretion and transforming hormone function. Therefore, the prostate of black and white people can only grow rapidly to meet the stringent requirements of a tall body, developed external genitalia, and prostate secretion and transforming hormone function during growth and development.
In this case, the prostate size of black and white people is naturally slightly larger than that of yellow people.
2. The size of the prostate is influenced by age.
(1) Before the age of 22-24, the prostate size is relatively small.
Like other organs in the human body, the prostate gland is not as large as it was from the beginning. Generally speaking, before the age of 22 to 24, men's prostate gland has been at the extreme of continuous growth and development. In other words, before the age of 22-24, the size of the prostate gland in men is usually smaller than 40 × thirty × 20mm.
Of course, this only applies to yellow people, and we should never compare it to black and white people.
(2) After the age of 45, the prostate size is relatively large.
Human organs, including the prostate, age and necrosis when they grow and develop. After the age of 45, the prostate gland of a male will gradually develop aging and necrosis, and the secretion of hormones, transforming hormones, and functions that attack the whole body will gradually decline, unable to continue to meet the needs of the whole body. At this time, the prostate gland will compensate for lost function through compensatory growth.
On this basis, it is inevitable that the actual size of the prostate is greater than 40 × thirty × 20 mm.
Next, let's take a look at how men over the age of 45 can determine whether the prostate size is normal:
① The difference between the left and right, upper and lower diameters of the glands is greater than age - 44, indicating a relative increase;
② The difference between the left and right, upper and lower diameters of the glands is ③ For patients of any age, the gland value is greater than '60' × fifty × "40mm" is an increase.
