Patient's question:
Okay, here is the translation following your instructions:A normal person has two testicles, but Brother has one extra. He's too embarrassed to see a doctor and wants to ask: Why do some men have an extra testicle? What are the effects? Will it affect future fertility? Who can help clarify this? Thank you very much!
Doctor's answer:
Your brother has three testicles, two more than the normal number. This condition is likely due to an extra testicle that developed during his embryonic growth and development. This is often related to his chromosomal genes, as well as the influence of embryonic expansion drugs or environmental chemical substances. Having an extra testicle generally does not affect future fertility. It is recommended that your brother have a medical examination to check his chromosomes and reproductive organs.
