Question
Does a child need surgery if one testicle is larger than the other? We have been worried about this situation for some time as parents, and we hope the doctor can give us some advice.
Answer
Normal testicles are not always of equal size on both sides. According to statistics, the right side is slightly larger than the left. As long as both sides are within the normal size range, it will not affect fertility. Some people have been one size larger or smaller since childhood, with one testicle very small and soft, while the other compensates by growing larger, with a very noticeable difference. This is congenital unilateral testicular underdevelopment. In summary, if the difference between the two sides is not significant and both are within the normal size range, it will not affect fertility. If one side is smaller and the other is normal, fertility may be lower, but it is still possible to have children. When one side is abnormally large or small, it is necessary to consider whether there is a disease present, and one should go to the hospital’s urology department for examination and treatment promptly.
