What if my eggs don’t fertilize?
Most eggs will fertilize when they are placed in a culture dish with several thousand normal sperm. This process is called “in vitro fertilization” or “IVF.” When there are not enough normal functioning sperm for IVF, fertilization will usually occur after a single live sperm is injected into each egg, termed “intracytoplasmic sperm injection” or “ICSI.” On rare occasions, fertilization does not occur even with ICSI, presumably because of a problem inherent to either eggs or sperm. In these cases, the use of donor sperm or donor eggs will usually result in fertilization. Your fertility specialist and IVF laboratory personnel will help you determine which approach is most likely to result in egg fertilization.
