OMG, how stupid can you be?!!
Serves him right! Honesty with his wife and a trip to the doctor right away would have been the better path after his poor choice of the seedy intimate encounter that caused his pain.
If he's a farmer, he should know a bit more than to spray a restricted use herbicide on his skin, anywhere, especially his scrotum. Sorry, not a lot of sympathy for the pain he went through, but a lot of sympathy for his wife!
