Patient's question:
Medical Description: In childhood, I developed the habit of masturbation. Gradually, I noticed that the left testicle was larger than the right, and the sperm produced seemed to be less in quantity. Could it be that the right testicle has already died? Now, when I occasionally masturbate, I find that the time is too short, and I ejaculate very quickly. Is it that my sexual function is not working properly?History of Treatment and Effects: I have never received any treatment.
Desired Help: Please help me clarify my doubts. I have read online that it is normal for the left testicle to be larger than the right, but in my case, it is the opposite. I am very worried and hope you can help me. Thank you!
Doctor's answer:
The male body has two testicles, located on the left and right sides of the scrotum. The testicles are oval-shaped and grayish-white in color. In adults, the testicles are 3.5-4.5 cm long, 2-3 cm wide, and 1-2 cm thick, with each testicle weighing 10-15 grams. Generally, the left testicle is about 1 cm lower than the right. Some people have one testicle that is larger or smaller, or one that is higher or lower. If the difference is not significant, it is considered normal. Statistics show that the right testicle is slightly larger than the left. As long as both testicles are within the normal size range, it will not affect fertility.Some individuals have one testicle that is much larger or smaller since childhood. One testicle may be very small and soft in texture, while the other compensates by becoming larger, with a very noticeable difference. This is known as congenital unilateral testicular dysgenesis. Trauma to one testicle can also result in one being larger or smaller. The injury may cause bleeding or a hematoma inside the testicle, leading to insufficient blood supply and gradual atrophy, making the affected testicle significantly smaller than the other. Some people, as children, suffered from mumps complicated by orchitis, where the virus damaged the epithelial cells of the seminiferous tubules in the testicle, causing one testicle to atrophy and resulting in one being larger or smaller.
