Hi I have has icis once and failed was just reading up on it and came across this on a Sydney internet page which has really scared me has anyone heard this before ;;;(With ICSI the scientist picks the one he/she thinks looks good, but there's a lot you can't tell about sperm by just looking at them. There is some evidence that ICSI might results in more birth defects but the science is inconclusive - they basically haven't been doing it for long enough.)
