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
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
