What do testicles look like in pictures?

Male testicles (located in the scrotum, one on the upper and one on the lower. Male testicles are slightly flattened ellipses with a smooth surface, divided into the outer edge, front edge, upper and lower edges. The outer edge is mineral acid; the edge has blood vessels, nerves and lymph vessels entering and exiting, and touches the epididymal cyst and the lower part of the ejaculatory duct (male testicle). Male testicles grow and develop rapidly with estrus, and the male testicles of the elderly shrink with the decline of sexual function.

There is a thick chemical fiber membrane on the surface of the male testicle, called the white membrane. The white membrane thickens along the edge of the male testicle and protrudes into the male testicle to form the male testicular septum. Many connective tissue septa extend from the septum, dividing the male testicular essence into many male testicular lobules.

What are the pictures of male testicles?

The male testicle is a key organ of the human body. Its main function is to produce androgen and sperm, and participate in maintaining the secondary sexual characteristics and reproductive function of human beings. The male testicle is mainly oval in shape, one on the upper and one on the lower, and exists in pairs. The size of male testicles is somewhat different, roughly the size of eggs, or larger. If you want to know the details of male testicles, you can go to the hospital outpatient clinic to do a scrotal color Doppler ultrasound examination to confirm the diagnosis. This is a very simple and quick examination method.

The testicular lobule contains the convoluted seminiferous tubules, and the epithelial cells of the seminiferous tubules can produce sperm. The connective tissue in the middle of the tubules contains homogeneous somatic cells that metabolize male hormones. The seminiferous tubules fuse into the straight tubules, which enter the testicular septum and interweave into the testicular rete. From the testicular rete, 12 to 15 testicular efferent ductules are transmitted, and they exit the upper end of the testicular edge and enter the epididymal cyst.

The testicles are part of the male internal reproductive organs. Normal men have two testicles, one on each side of the scrotum. The testicles are oval in shape and grayish white in color. The testicles of adults are 3.5-4.5 cm long, 2-3 cm wide, 1-2 cm thick, and weigh 10-15 grams on each side. Generally, the left testicle is about 1 cm lower than the right testicle. Some people have one testicle that is larger than the other, one that is higher than the other. If the difference is not significant, it is normal. There are many curved seminiferous tubules in the testicles, with interstitial cells in between.

The seminiferous tubules are the area where sperm is produced. The number of sperm produced in a man's lifetime is astonishing. A man ejaculates 3-4 ml of semen each time, containing 300-400 million sperm, and as few as 100-200 million. The number of sperm produced in a lifetime is as high as more than 1 trillion.

The production of sperm is easily affected by many factors such as temperature. If the temperature around the male testicles is too high or is affected by organic chemical toxins, the production of sperm will be hindered. Interstitial cells produce male hormones, which are closely related to male secondary sexual characteristics and physiological functions.
