The male sexual organs are of the exposed type, consisting of the penis and testicles. During sexual life, the penis will "grow up" due to stimulation, and the testicles will also have certain contractive changes. But these are all superficial phenomena, and the "work" they do goes far beyond that. Do you want to know how the penis and testicles work? Let's take a look at the most scientific answers!
The operation of the penis in sexual intercourse
The main function of the penis is to urinate, excrete semen, and perform sexual intercourse. It is the main organ for sexual behavior. The skin of the penis is extremely thin, without fat under the skin, and has activity and extensibility. The blood sinuses of the cavernous body of the penis can attach to the blood.
"When there is no sexual impulse, the penis is spongy. When stimulated by sexual activity, the blood in the blood sinuses of the cavernous body of the penis increases, and the penis expands, thickens, hardens, and becomes erect. When the inflow of blood and the return of blood are equal, the penis continues to erect."; The nerves on the head of the penis are not slightly rich and extremely sexy. When sexual intercourse reaches its climax, the high excitement of the ejaculatory center causes ejaculation.
"Under sexual stimulation, if the penis cannot erect or the erection stiffness is insufficient, it is unable to engage in sexual activity, which is referred to as" impotence ". Abnormality of penis erection or penis deformity can cause sexual difficulties.".
The functioning of the testicles in sexual intercourse
The main function of the testis is to produce sperm and secrete male hormones (testosterone). The former is fertilized by combining with the egg, which is an important material basis for reproduction of offspring, while the latter is an important material for maintaining male secondary sexual characteristics (parasexual characteristics).
"In the early stages of the embryo, the testicles are located in the abdominal cavity, precisely at the inner ring of the inguinal canal, and gradually decline. By the seventh month, the testicles quickly pass through the inguinal canal and fall into the Yin steamed bun, while the upper parts of the testicles are locked.".
During the process of testicular descent to the scrotum, various abnormalities can occur, such as incomplete or incomplete occlusion of the tunica vaginalis, hydrocele of the tunica vaginalis, cysts of the spermatic cord, and hernia; If the testicle fails to descend completely and stops in the abdominal cavity or inguinal canal, it is called "testicular insufficiency", or "cryptorchidism"; "If the testicle does not reach the scrotum when it descends and deviates to the perineum, penis root, thigh, etc., it is called" ectopic testicle. "". Abnormal testicular position affects the quality and quantity of sperm production and development, which is not conducive to fertility.
