What are the consequences of having only one testicle?

The male testicle is located in the scrotum, one on each side, usually 1cm lower on the left side than on the right side. The male testicle is slightly flattened and oval, with a smooth surface, and is classified into two sides, front and back edges, and upper and lower sides. Its outer edge is mineral acid; blood vessels, nerves, and lymphatic vessels enter and exit the edge, and it touches the male testicle part of the epididymal cyst and ejaculatory duct. The upper and edge are attached to the epididymal cyst head, and the lower side is mineral acid.

What are the consequences of having only one testicle for boys?

Men have a pair of testicles. Even if one testicle is lost due to an accident, men can still maintain their male characteristics. Testicles are key organs in maintaining male reproductive function and sexual characteristics. If the testicles of adult men are too large or too small, it will affect the reproductive function. For those who have been married for many years but have not had children, this should be taken seriously.

The size of the testicles is related to age. From newborns to children under 12 years old, male testicles are in a relatively quiescent period, with a general volume of 1 to 4 ml. After 12 years old, boys enter puberty, and the volume of male testicles expands rapidly. The volume of male testicles of adult men is about 16 to 25 ml, with an average value of . After 60 years old, they enter the stage of sexual decline, and the volume of male testicles gradually shrinks. After 70 years old, the volume of male testicles can shrink to less than 16 ml.

When a testicle is missing, many people will think of eunuchs in the palace, who have male sexual dysplasia, lack of sexual desire and male sexual function. In fact, this is a misunderstanding. Eunuchs often lose some of the characteristics of men because both of their male testicles are cut off.

The testicle is a human organ that produces androgens. If the testicle is lost and no androgens are used for treatment, it will naturally lead to the above-mentioned series of "castration" symptoms, as well as loss of sexual desire and sexual function. However, if one testicle is left out, the situation will be very different. There are many paired internal organs in the human body, such as the lungs and kidneys. These internal organs have a characteristic that once one side of the internal organ loses its function or is damaged, the normal internal organ on the other side will take on the role of the internal organs on both sides, while expanding its own volume and enhancing its function. This is called compensatory hypertrophy in medicine.

Men have one testicle. For those men with only one testicle, as long as their testicular function is normal, they still have hope of getting pregnant. In fact, it is closely related to the sperm density produced by the testicles, and sperm count has a wide range of normal ranges. Therefore, as long as the testicular function is normal and can produce enough sperm to provide fertilization, pregnancy is still possible.
