During erection the genital organs are filled with blood. That is most visible with the penis (erection), but other organs are affected, too. This overflow can sometimes be excessive and cause too much blood to come in the testicles, thus causing pain. The left testicle is more affected due to anatomical causes (the left testicle is usually larger and positioned lower). The condition is not pathological. Masturbating for a shorter period might decrease the frequency and intensity of the pain.


You might want to visit a urologist to check for urinary or genital infections and the presence of varicocele which might worsen the condition.
