Can varicocele cause infertility, and what is the best surgery if it comes back?

Yes, a varicocele can cause testicle pain, heaviness, and is a major factor in low sperm count and male infertility. If you have a recurrent varicocele (varicocele came back after surgery), advanced microsurgery for varicocele (Microsurgical Varicocelectomy) is the most effective treatment with the lowest recurrence rate. Get treated by Dr. Gautam Banga, a top varicocele specialist in Delhi, to safely resolve the 'bag of worms' sensation and improve fertility.
