Intra-cytoplasmic sperm injection (ICSI) is the same process as in-vitro fertilization (IVF), but instead of mixing the egg and sperm together, a single sperm is injected into the egg. ICSI is used for men with extremely low sperm counts, low motility, or those who have a history of no fertilization occurring at a previous IVF cycle.
At the MFC, we do not believe that ICSI should be performed unless it’s absolutely necessary. In our experience, allowing an egg to be fertilized through more conventional IVF will produce better-quality blastocysts (embryos) in the majority of cases.
It is important to note that ICSI does not guarantee fertilization of an egg. At the MFC, the normal fertilization rate by ICSI is approximately 75%.
