  • Range from sharp to dull uneasiness
  • Deteriorate over a day
  • Increase with standing or heavy work, particularly over an extended duration
  • Be relieved while lying in the back position

Gradually, varicoceles may widen and become more visible. The condition may result in a swollen testicle, mainly on the left side.

Varicocele forms when there is an improper blood flow in the valves inside the spermatic cord’s veins. Then blood backs up, resulting in swelling and widening of the veins. Varicoceles often develop during puberty. Generally, it arises on the left side due to the position of the left testicular vein.


What is the effect of varicoceles on sperm?

Varicoceles might raise the temperature around the testicle, which affects sperm formation, movement, and function. Also, it can generate inadequate blood supply in the testis.

What is the treatment for varicocele?

Varicocele is treated when males are experiencing pain or discomfort.

Varicocelectomy is a surgical process to correct a varicocele. In this process, the swollen veins are tied off. Then the collected blood is forwarded to the healthy veins. If the sperm parameters (number, motility, or morphology) are impaired, IVF/ICSI is the treatment option to help the couple to get pregnant.
