Varicocele rarely causes pain, and when it does, it may: range from intense to dull discomfort degrade over a day increase with standing or hard activities, especially for extended periods of time be relieved while laying in the back positionVaricoceles may enlarge and become more obvious with time. A testicle that is primarily on the left side may swell due to the disease.

When blood flows improperly via the valves inside the veins of the spermatic cord, varicocele develops. Blood then backs up, causing swelling and vein widening. During adolescence, varicoceles frequently appear. Due to the location of the left testicular vein, it typically develops on the left side.

Varicoceles may increase the temperature in the area around the testis, which could have an impact on sperm development, motion, and function. Additionally, it may result in insufficient blood flow to the testicles.

Men who have varicocele are treated when they feel pain or discomfort.A varicocele can be treated surgically with a varicocelectomy. The enlarged veins are tied up during this procedure. The blood is then sent to the healthy veins. IVF/ICSI is a therapy option to assist the couple in becoming pregnant if the sperm parameters (number, motility, or morphology) are compromised.
