Whenever I flex my abdominal muscle (like when you cough), only my left testicle contracts/rises. The right testicle does not react. I'm 18 now and I've noticed this for 5 years. Nothing has been wrong with my testicles besides this problem. Possible causes/treatment?
Shouldn't be a problem.... I've lived with it all my adult life. (one testicle moves the other doesn't when I flex abdominal muscle). I'm 54 and have fathered one boy and one girl. And I never saw it as a problem... just an oddity or quirk.
