How does a positive ASAB test affect IVF sperm and egg preparation and fertilization?
If the husband tests positive for ASAB, his semen specimen for IVF will be collected into a specimen cup containing a buffer solution that will minimize the effect of ASAB on the sperm. Normal IVF fertilization rates (fertilization of 50% or more of the mature eggs) are usually achieved with this treatment. When the female partner or both partners have tested positive for ASAB, or if the husband also has a compromised semen specimen (low count, low motility or low SPA), fertilization rates may be lower and your physician may suggest ICSI.
