Hello! This is Dr. Klarida Papaqako answering your question. Having a varicocele (testical varicose) is thought to increase the chance of being infertile but most men with a varicocele are not infertile. Treatment is not usually needed, as most men do not have any symptoms or problems caused by the varicocele. If there are symptoms symptomatic treatment is recommended- scrotal support or analgesics according to the symptom. If required, an operation can clear a varicocele. Some methods that can be used are venous ligation or embolization with a success rate 90%-95%, laparoscopic surgery (expensive but better for bilateral procedures) or radiologic embolization via groin catheter (expensive, good for recurrent varicocele). However, remember that most men with a varicocele are not infertile. Take care, Regards.
