When ICSI may not be best…

images-6ICSI (intracytoplasmic sperm injection) is a form of IVF that was developed to help overcome male fertility problems by injecting sperm directly into eggs, but in recent years is often used far more widely and sometimes in cases where there isn’t a male factor problem at all. Patients are often told that ICSI improves the chances of success, but a new study from the States has found that this is not the case unless there is a male fertility problem.  In fact, in cases where there is no male factor problem, ICSI is associated with lower rates of implantation and live birth than conventional IVF.

The research was a big retrospective study looking at more than 1 300, 000 IVF and ICSI cycles from 1996 to 2012.  The use of ICSI in the US in this period had gone up from 36% of cycles to 76%, but it was not associated with improved outcomes.

The research is published by the Journal of the American Medical Association, and you can read the full findings on their website – http://jama.jamanetwork.com
