Male genital self-testing needs to check the development of the scrotum and testis, penis, and foreskin, and comprehensively evaluate the growth of the pubic hair. Precautions for male genital development self-test: inappropriate population: none. Contraindications before inspection: Wash hands before inspection. Requirements for examination: If the testicular volume is abnormally abnormal, the urologist should be examined in detail to find out the cause. The testicles are sensitive to the pressure exerted by the fingers, and attention is not given to excessive force when touching. Excessive skin and phimosis can affect sexual life, and can induce balanitis, so it should be surgically removed early.

Basic Information

Specialist classification: male examination inspection classification: physical examination

Applicable gender: whether the male is fasting: not fasting

Tips: If the testicular volume is abnormally abnormal, you must promptly check the urology surgeon for the cause. Normal value

The adult testicles have a volume of approximately 2 x 4 x 3 cm3, which is 2 cm thick, 4 cm long and 3 cm wide. The testes on both sides should be approximately equal in volume, smooth in surface, oval in shape, and have a certain degree of mobility in the scrotum. The foreskin phimosis is normal.

Clinical significance

The second phase of the abnormal results is no earlier than 11 years old, and no later than 18 years old. If the genitals still have no pubic hair after the age of 19, or if they have long pubic hair before the age of 11, they should go to the hospital for examination.

The male genital developmental stage of the population to be examined.

Precautions

Inappropriate crowd: None.

Contraindications before inspection: Wash hands before inspection.

Requirements for examination: If the testicular volume is abnormally abnormal, the urologist should be examined in detail to find out the cause. The testicles are sensitive to the pressure exerted by the fingers, and attention is not given to excessive force when touching. Excessive skin and phimosis can affect sexual life, and can induce balanitis, so it should be surgically removed early.

Inspection process

The developmental age of the testis is between 10 and 18 years old, and the apparent developmental period is between 12 and 16 years old. The size and volume of a mature testicle can be roughly determined by a two-handed examination. When checking, put the two testicles in front of the thumb with both hands, the food of the hands and the middle finger are placed behind the testicles, and touch the outline and size of the two testicles. The adult testicles have a volume of approximately 2 x 4 x 3 cm3, which is 2 cm thick, 4 cm long and 3 cm wide. When the testicular volume is measured, the thickness between the inner and outer sides is the width between the front and rear edges, and the length between the upper and lower ends. The testes on both sides should be approximately equal in volume, smooth in surface, oval in shape, and have a certain degree of mobility in the scrotum. Its size is above and below the above standard range, and it should not be considered abnormal if it is slightly larger or smaller. If the volume is obviously abnormal, you must promptly check the urology surgeon for the cause. The testicles are sensitive to the pressure exerted by the fingers, and attention is not given to excessive force when touching.

The age of male penis development in penis is between 11 and 17 years old, that is, it begins to develop from about 11 years old. Many teenagers always think that their penis is too small or too short, which is not necessarily correct. The penis is in a state of stagnation and a full erection state, and its volume is so large that it cannot be judged to be too small in its sallow state. When the erection is sufficient, the length of the penis is less than 10 cm, and the penis is considered to be short. In addition, the development of the penis is determined in combination with the development of the shape and volume of the penis.

The foreskin is too long and the phimosis is somewhat confusing for the foreskin and the phimosis. In fact, the difference between the two is greater. In childhood, the foreskin wraps the entire penis head. As the external genitalia develops, the foreskin gradually recedes to the back of the penis head. If the penis head is completely covered by the foreskin in adulthood, it is called "the foreskin is too long"; if the foreskin is narrow, the foreskin can not be retracted and turned over to the back of the penis head, which is called "phimper". Because the foreskin is too long and the phimosis can affect sexual life, and can induce balanitis, it should be surgically removed early.

Not suitable for the crowd

There are no specific taboos.
