That very much depends on the quality of your sperm at the time of the procedure. The most sensible thing you can do now is to take the supplements for 6 months, live a clean lifestyle (no alcohol, cigarettes, fast food etc), reduce processed meats and sugar to an absolute minimum (if not eliminate meat altogether) and do take up yoga & meditation if you can. This should give you the best sperm your body can possibly produce in 6 months. The fertility specialist will then judge if your sperm is good enough for ICSI treatment. Wishing you the very best of luck!
