Why is the left testicle bigger than the right?

What is the reason for the left testicle to be larger than the right one? This question is more confusing for men, because men with this condition basically have no symptoms, just the appearance of the testicle is abnormal. However, it is necessary for people to pay attention to their own body parts. So, what is the reason for the left testicle to be larger than the right one? What is the impact on reproductive health? Let's take a look at the explanation below.

Some people have testicles that are one large and one small since childhood, and the difference is very obvious. This is mostly caused by congenital diseases. Among the congenital causes, there are two common ones: one is congenital testicular dysplasia, which is caused by a disease called Kleinfeldt syndrome, which is also called seminiferous tubule dysplasia. About one in 500 male babies has this disease. This disease is mainly caused by abnormal sex chromosomes. Normal males have 46 chromosomes, represented by 46, XY. Patients with Kleinfeldt syndrome have an extra sex chromosome X, and their karyotype is 47, XXY. The reasons may be that the mother's oocytes did not undergo meiosis during mitosis and formed double X eggs, or that the father's sperm was abnormal during production.

In addition, some people mistake other lesions in the scrotum for one testicle being larger than the other. For example, hydrocele is actually just a water bag around the testicle that wraps the testicle, not the enlargement of the testicle itself. Some people also mistake inguinal oblique hernia, varicocele, epididymal tuberculosis, epididymitis, etc. for enlarged testicles, because these diseases sometimes also manifest as one side of the scrotum being larger than the other side.

From the above introduction, the phenomenon of the left testicle being larger than the right is normal in most cases. Male friends do not need to worry too much about this situation. As long as they do not have bad habits, it is very important to keep their bodies healthy and stay away from reproductive diseases. Therefore, men must pay attention to this problem.
