How about an ICSI split?

Posted on 19:37 by Unknown
Life would be much easier for me if I had a crystal ball at work. Then I could be sure who needed ICSI and who didn’t. I could always be 100% sure of when to trigger with HCG for IVF and no one would ever get OHSS (ovarian hyperstimulation syndrome). Clearly there are honest differences of opinion between physicians and this can be confusing to patients who sometimes believe that there is an absolute right answer to medical questions. Sometimes there is an obvious answer but not always. So what do you do when 2 well-trained, well-educated physicians suggest different plans? That is the topic of today’s “Question of the Day” that goes hand-in-hand with yesterdays topic.

59. My husband and I were told by one RE that we needed ICSI, but another RE says that we don’t. What should we do?


ICSI is accepted as a standard treatment option for infertile couples with severe male factor infertility. In most clinics, approximately 50% to 90% of the eggs that are injected with sperm using ICSI will fertilize normally. Some eggs do not survive after injection with the sperm and subsequently degenerate. The criteria regarding what constitutes severe male factor infertility, however, vary from clinic to clinic. Some clinics use ICSI for all (or nearly all) patients based on the theory that assisted fertilization is better than no fertilization at all.

In general, ICSI is employed in cases where the semen analysis reveals abnormalities related to sperm count (less than 20 million/mL), sperm motility (less than 50% are motile), or sperm morphology (less than 30% have a normal shape). ICSI should also be considered in couples with no previous evidence of fertilization or a history of failed fertilization with a prior IVF attempt. In our clinic, we often perform an IVF/ICSI split. That is, the eggs that are collected during the oocyte retrieval phase are divided between normal fertilization and ICSI. If some component of male factor infertility is present, splitting the eggs between ICSI and IVF may reveal whether the sperm can actually fertilize an egg. If the eggs fail to fertilize with IVF but fertilize normally with ICSI, then the logical conclusion would be that the sperm is incapable of fertilizing the egg with IVF alone.

Couples with unexplained fertilization failure with IVF may have a problem with the sperm, the egg, or both. In such cases a repeat cycle of IVF using ICSI will usually yield good fertilization results and, ideally, a pregnancy.
