Patient's question:
What are the causes of varicocele? It has been many years, and I want to have children, so it's time to see a doctor.Doctor's answer:
The main cause of varicocele is the congestion of blood in the spermatic veins. Due to the upright posture of humans, the return flow of spermatic veins is affected; the weakness of the venous wall and surrounding connective tissues, or incomplete development of the cremaster muscle; and defects or incompetence of venous valves, making it prone to varicocele.1. Blood stasis in the dilated veins leads to an increase in local temperature of the testes, which affects spermatogenesis.
2. Blood stasis affects the blood circulation of the testes, resulting in a lack of necessary nutrients and oxygen supply, which impacts spermatogenesis.
