What are the reasons for ICSI failure rate for fertilization procedure 0 % ?
Since the fertilization rate was 0 % you think another protocol would have a different outcome?
ICSI is commonly used for reasons stated here http://www.hfea.gov.uk/ICSI.html. However, IVF doesn’t have a 100% success rate, not even when using ICSI. There are many factors that can affect this, including (but not limited to), egg/sperm quality, age, decreased blood flow to the pelvis, hormonal imbalances, etc. Does this help?
Poor sperm DNA fragmentation is an important reason for IVF or ICSI failure. This cannot be seen on a standard semen analysis and has to be tested for separately. At our clinic we advise patients to use the SpermComet test. Reasons for a high rate of fragmentation include but are not limited to smoking, alcohol, poor diet, environmental toxins. DNA fragmentation can sometimes be improved using high quality anti-oxidants and nutritional therapy. For further information see http://www.spermcomet.com and http://www.thenaturalfertilitycentre.com
