ICSI may give you and your spouse a chance of conceiving your genetic child when other options are closed to you.
If your spouse is too anxious to ejaculate on the day of egg collection for standard IVF, sperm can instead be extracted for ICSI.
ICSI can also be used to help couples with unexplained infertility, though experts haven't found that ICSI makes pregnancy any more likely than standard IVF.
ICSI doesn't appear to affect how children conceived via the procedure develop mentally or physically.
