Testicular pain after chiropractor visit?

I know this is a women’s health platform but I have a question regarding male genitalia.. My husband went to the chiropractor today because he threw his back out last weekend and he told him he had a herniated disk. So he gave him an alignment and did a bunch of work to try getting the disk back in place but said it would take at least a few more visits cause it started bothering him years ago. Anyways, he came home earlier and tonight he said his right teste was sore and he was genuinely concerned it was from the adjustment. He said he thought he gave him ball cancer 😂 I assured him it was probably not abnormal after having a major alignment like that. I obvs do not know much about male anatomy as far as pain goes nor have I ever been to a chiropractor. Does anyone know if this is normal at all?
