The sofa is a destroyer of male testicles

　　Normal people's testicles are unequal in size on both sides, but the difference is generally not too big. If the testicles on both sides were basically similar in size in the past, and one testicle suddenly appears to be significantly enlarged in the near future, you should seek medical advice promptly. Hospital Carry out inspection.

　　Nowadays, more and more people sit on soft sofas. Some people sit on the sofa and watch TV for several hours without moving. No one would have thought that this soft and comfortable sofa would actually cause damage to the function of the testicles.

　　Get to know our testicles
　　
　　The internal structure of the testicles is surrounded by a tough layer of tissue called the tunica albuginea, which protects the testicles. The tunica albuginea thickens and extends inwards, dividing the testicles into many compartments. These compartments are called the testicular mediastinum, and the compartments are called testicular lobules. Normal men generally have 200 to 300 lobules, which are filled with testicular substance and are responsible for the production of testicles. sperm The place is called the seminiferous tubule. If you cut out a small piece of testicular parenchyma and observe it under a microscope, you can see that the seminiferous tubules are thin tubes.
　　
　　testicular data
　　
　　In adults, the diameter of each seminiferous tubule is 150 to 250 microns, and the length of each seminiferous tubule is 30 to 70 cm, with the longest one reaching 150 cm. There are about 300 to 1,000 seminiferous tubules in a testis, with a total length of 200 to 300 meters. Obviously, the base for sperm production in the testis is quite large. The seminiferous tubules in each testicular lobule merge into 2 to 3 straight seminiferous tubules to form the rete testis, and then merge into 15 to 20 testicular efferent tubules to communicate with the epididymis. Sperm enter the epididymis through this channel to mature. The seminiferous tubules are the base for sperm production. Why does such a small tube have this magical ability? It's really hard to explain. There are quite complex subtle changes in cell biology and biochemistry. To this day, scientists are still painstakingly exploring its origin. Nonetheless, the basic processes of sperm production are now recognized.
