Males have testicles in a contained sac (scrotum) which lies outside of the body between the legs which makes it embarrassing to scratch when one has a scrotal itch. Commonly, dryness of scrotal skin due to use of harsh soaps or old age may lead to scrotal itching. However, over sweating in the groin area after walking around during a hot day or overdressing in tight clothes can cause the same problem. Many men do not wash their scrotum properly or not at all leading to accumulation of sweat, skin oil and dirt which when combined cause itching.
