What are the causes of varicose veins?

Varicocele affects the quality of sperm due to local high temperature, blood circulation disorders, blood reflux, etc.

1, local high temperature

sperm is not easy to survive in high temperature environment, and varicocele will lead to local temperature rise, thus affecting the survival and quality of sperm.

2, blood circulation disorders

Varicocele will affect the normal blood circulation of testicular parts, resulting in lack of nutrition and oxygen supply in testicular parts, thus damaging sperm production and quality.

3, blood reflux

When varicocele causes vascular blockage, it is easy to cause blood reflux, thus affecting the blood supply of testicular parts leading to excessive contraction of testicular blood vessels, so that immature sperm fall off prematurely, affecting sperm quality.
