I was diagnose with varicocele on my left testis which affect my sperm count what can be done to improve my sperm count?

Urologist: Yes. It would affect fertility especially if other possible reasons are excluded. This can be fixed. You need to get a referral to a urologist.

Varococele Fertility: A varicocele may affect sperm but not always. You need a sperm analysis to check for quality. The numbers alone may suggest poor function but unless the numbers are very poor, you should try for a while. You cannot think of just you, as female factors can affect getting pregnant. You need help from a fertility specialist to get more info - not enough space here. Best wishes.

Varicocele Low Count: Varicocele could be the cause of your low sperm count but it is more likely to affect sperm motility. Also, surgery does not always correct the problem, so check for other fertility factors including female factors before deciding on surgery. I have an acrosome reaction sperm test that helps me. If test is normal then surgery less likely to help. See both male & female specialists to decide.

Varicocelectomy: Can be corrected by inguinal microdissection to tie off spermatic veins, laparoscopic spermatic vein clipping or ligation or more invasive open inguinal spermatic vein ligation. Vein occlusion by interventional radiology by injecting micro-coils can achieve similar result but results tend to be less successful in my experience.
