I doubt if it is something internal if the itching is only on your scrotum
. It is most likely a type of "jock itch" without the rash
of a fungal infection
. In the summer, itching is very common due to sweating and moisture build-up. The skin gets irritated and itches. If you wear tight, jockey style underwear, but sure to get some "air time" for your scrotum during the evening or night. Wash the scrotum twice a day, but not too much soap. Dry it well, and then apply a moisturizing cream or lotion. I suspect your itching will go away with a new routine.
