What are normal testicles like?

Many men who don't know much about testicles want to have a comprehensive understanding of what normal testicles are like. The following content provides a detailed introduction to this knowledge for many men who want to have a comprehensive understanding of this aspect. For many people who want to understand it as soon as possible, you can have a specific understanding of the following content. I believe that through understanding, you can have a comprehensive understanding of this knowledge.

Structure

The surface of the testis is covered with a thick fibrous membrane called the tunica albuginea. Along the posterior edge of the testis, the tunica albuginea thickens and protrudes into the testis to form the testicular septum.

Tissue septa divide the testis into many lobules. The lobules contain convoluted seminiferous tubules, whose epithelium can produce sperm. The connective tissue between the tubules contains interstitial cells that secrete male hormones. The seminiferous tubules combine to form straight tubules, which enter the testicular septum and interweave to form the rete testis. From the rete testis, 12 to 15 efferent ductules of the testis emerge and enter the epididymis from the upper part of the posterior edge of the testis.

Testicles are male internal reproductive organs. Normal men have two testicles, one on the left and one on the right side of the scrotum. Testicles are oval in shape and grayish white in color. Adult testicles are 3.5-4.5 cm long, 2-3 cm wide, and 1-2 cm thick. Each testicle weighs 10-15 grams. Generally, the left testicle is about 1 cm lower than the right testicle. Some people have one testicle that is larger than the other, or one that is higher than the other. If the difference is not too big, it is normal. There are a large number of curved seminiferous tubules in the testicles, which contain interstitial cells. The seminiferous tubules are where sperms are produced. The number of sperms produced in a person's lifetime is astonishing. A single ejaculation of 3-4 ml contains 300-400 million sperms, and as few as 100-200 million. The number of sperms produced in a lifetime can reach more than 1 trillion. Sperm production is easily affected by many factors such as temperature. If the temperature around the testicles is too high or affected by chemical toxins, sperm production will be impaired. Interstitial cells produce androgens, which are closely related to male secondary sexual characteristics and physiological functions.

What are normal testicles like? The above is an introduction. I believe that through the above introduction, many people have already understood what normal testicles are like? After understanding, in order to protect your own testicular health, you must usually take good care of it, so as to ensure that your testicles can always be in a healthy state.
