A monthly self-exam of the testicles is recommended.
Some men do this after a warm bath or shower, so the scrotal muscles are more relaxed and the skin is softer. The testicles should first be visually examined to look for bumps or swelling. Then they should be palpated by holding the scrotum and testicle in the hand. Gently roll the testicle back and forth between the thumb and forefinger. Abnormal findings in the testicles that warrant further evaluation are a painless swelling or lump, any change in how the testicle feels, any change in size, an acute build-up of fluid in the scrotum, or pain in the testicle. Further testing may include an ultrasound, a painless procedure during which high energy sound waves are bounced off the testicular tissue.
