Testis is the male internal reproductive organ, the processing factory of sperm and androgen, and the engine of male sexual desire. Testicles are very sensitive to the environment and prone to various problems, so men should pay attention to the self-examination of testicles. When should the testicular examination start? First of all, the testicles should be examined from the birth of a boy, so that diseases such as cryptorchidism can be found early, which needs to be completed under the guidance of a doctor. Secondly, under normal circumstances, the testicles of boys grow rapidly from 1 12 years old to 18 years old, and complete normal puberty development. If the testicular volume does not increase after 12 years old, it is necessary to seek medical advice in time to rule out the possibility of delayed puberty. Finally, it is suggested that testicular self-examination should be carried out once a month from the age of 15, so as to know the size, shape and touch of testis at any time and find diseases such as tumors early.
The best time for self-examination is after bathing, when the scrotal skin is looser and easier to check. The specific method of testicular self-examination: take a standing position, make the scrotum droop naturally, hold the scrotum up with your palm, and observe and appreciate its size and weight. Hold the testicles gently with your hands, with your thumb in front of them and your forefinger and middle finger behind them. Turn the testis gently with your index finger and thumb to check its size, smooth surface, lump and tenderness, and pay attention to the difference between the left and right testicles. If there is an abnormal lump, you should be vigilant and consult a male doctor as soon as possible.
