Varicocele embolization is an image-guided procedure that uses a catheter to place tiny coils and/or a liquid substance in a blood vessel to divert blood flow away from a varicocele.

A varicocele is an enlarged vein in a male's scrotum with reversed or stagnant blood flow. It can cause pain, swelling and infertility. A clinical examination can confirm the presence of a varicocele and an ultrasound examination may allow further evaluation of the findings.

Varicocele embolization safely relieves that pain and swelling and may improve sperm quality for infertile couples.
