Hello, Thank you for posting your worries on this forum. I will try as much as possible to elaborate on this issue as it is very sensitive and normally you need to discuss this with your doctor. They occur in 15-20% of all males. Usually diagnosed in males between 15-30 years and rarely above 40. Varicocele can be harmless, but in many cases it can cause infertility and pain. Although there are studies showing improvement in sperm quality in 57%, there are also studies showing that the regular surgery has no significant effect on infertility. Thus the surgery may not improve fertility and the patient will need to undergo a non-invasive treatment However researches show that if the treatment is performed adequately, both sides by interventional radiology procedure or by microsurgery, sperm production can be restored even in men without sperm cells at all (azospermia). Chances are, if your husband meets a specialist early enough either an interventional radiologist or a urologist he could get his condition corrected soon enough and fertility could be restored. hope this helps
