Lauren, can I ask, do the statistics actually show that ICSI has a higher fertilisation rate? I would have thought that IVF is higher because it allows the best sperm to penetrate the egg as it naturally would, where as with ICSI, they have to take a guess at which sperm seems best.
Naty, I read a website saying that failure of an egg to fertilise is generally a sperm issue. If it fertilises but is poor quality then it is generally an egg issue. Sorry I can't find the site again to post up the link.
My experience:
My hubby has 100% abnormal sperm.
IVF 1: 1 egg retrieved. Fertilised but disintegrated before ET.
IVF 2: 4 mature eggs retrieved. 2 fertilised normally, 1 fertilised abnormally with only one pro-nuclei and 1 didn't fertilise. 2 embryo's transferred but poor quality. BFN.
IVF 3: 3 mature eggs retrieved. 1 of 3 fertilised. Great quality. 1 transferred but still BFN. (Blaming the hospital getting trainee to do my transfer!)
So as you can see we don't have a great fertilisation rate either which I definitely put down to hubby's sperm. It is interesting that my embryo quality has improved each time so I definitely believe the website that says the embryo quality is up to me because I can see improvements with each IVF and I have been working so hard since my first failed IVF with a high protein diet, acupuncture and supplements.
Oh, if it helps, DH's first sperm analysis showed low count as well as low motility and abnormal morphology (the works!). I studied what supplements can help and after a couple of months, his count and motility were both way up and in the normal range (but still 100% abnormal morph which is the hardest to change without diet which my husband is very slack at). So I would definitely start him on the supplements before your next IVF if low count is the only issue.
One more point is that I tried to have sex every day for 5 days leading up to ER. One study showed that men who ejaculted daily for 7 days had 20% less DNA damage in their sperm. Gets the older sperm out that has been exposed to the bodies oxidation process. Maybe that also helped with our embryo quality?
I have done lots more but will stop for fear of boring you to tears and you can ask any questions you like. But maybe I am not the best person to ask seeing as I am not yet able to score a BFP for myself! Starting IVF again early March.
