The appropriate term for a guy with only one testicle is monorchid. Since you can’t go around calling someone a monorchid, I have compiled a list of popular nicknames for guys with one testicle.
Monorchism describe the state of having only one testicle within the scrotum and it can happen for several reasons.
One of the reasons a guy might have one testicle is due to injury. For example, Brian Foster, a former UFC 129 fighter literally lost a testicle as a result of a kick to his groins.
Another reason a guy might have one testicle is due to testicular cancer or the possibility of testicular cancer. For example, Nigel Farage, former leader of the UK Independence Party had a testicle removed due to testicular cancer.
Also, a common reason why a guy might have one testicle is due to an undescended testis. For example, Adolph Hitler had one testicle due to cryptorchidism; undescended testis.
To answer the question that is on your mind, a man with one testicle can live a normal life. Having one testicle can be awkward but it doesn’t affect sex or reproduction.
So, what type of nicknames can you call a guy with only one ball?
