The testicles are an important “factory” for the production of androgens and sperm, and play an important role in maintaining male sexuality and fertility. Therefore, the testicles are responsible for a man’s lifelong “sexual well-being” and are also responsible for the important mission of passing on the family name, so it is very important to pay attention to testicular health. When the testicles are diseased, what distress signals will be given to us? Stick your hand in your pants and give your testicles a medical checkup in the following order. First, count the number of testicles. Reach down and feel your scrotum to see how many “balls” there are in total. If you feel 2 “balls”, you can breathe a sigh of relief. If one side of the scrotum is empty and you only feel 1 “egg”, you should pay attention to this situation and consider that there may be cryptorchidism or congenital monorchidism. At this point, if you feel 3 “balls” in the scrotum, don’t smile there, more than 2 testicles is called “polyspermia”, such people have a higher probability of testicular torsion or malignancy than normal people, so you should go to the hospital to assess the risk. The second step is to feel the size of the testicles. The size of the testicles varies according to race, genetics and other factors, and the size of a normal adult male’s testicle is about 15-25 ml. If you feel your testicle is as small as a peanut rice, you should pay attention and wonder if there is congenital testicular dysplasia due to chromosomal abnormality or testicular atrophy caused by testicular infection. If you feel your testicles are big, don’t be proud of them, especially if they are painlessly swollen and hard, be alert to testicular tumors; if they are swollen and feel cystic when pressed, and the pressure pain is not very obvious, suspect testicular syringomyelia; if they are red and swollen, with obvious tenderness, it may be an infection that causes testicular inflammation, and also be highly alert to – testicular torsion. -testicular torsion. Next, feel the testicle and the surrounding area for any abnormal nodules or blood vessels. If you feel a round lump on the head of the epididymis with smooth surface, no obvious pressure pain and cystic feeling, it may be a seminal cyst; if the epididymis is thickened with obvious pressure pain, it may be an inflammation of the epididymis; if the epididymis and the nearby vas deferens are thickened with slight pressure pain or no pain, and bead-like nodules can be palpated, you should beware of epididymal tuberculosis. If you can feel the tortuous blood vessels around the epididymis of the testicles, like a mass of earthworms, you should suspect varicose veins of the spermatic cord. The “self-touch physical examination” is only a preliminary judgment of testicular health, it is recommended that friends who find testicular abnormalities go to a regular hospital for detailed consultation and treatment. The important thing to say twice is that the testicles are responsible for a man’s lifelong “sexual well-being” and also for the important mission of passing on the family name, so it is very important to pay attention to testicular health.
