Men with severe oligospermia are encourage to seek genetic counseling and karyotyping due to the increased risk of genetic caused for this condition. With any reproductive technology procedure, women who conceive are encouraged to consider genetic evaluation of the fetus through chorionic villus sampling or amniocentesis. Oocytes exhibiting polyspermic fertilization will not be used for embryo transfer or cryopreservation. This process is done prior to transfer by applying tiny amounts of enzymatic solution with the aid of the micromanipulation microscope. The process is thought to improve the hatching, or escape, of the blastocyst from the zona pellucida.
Age is the predominant determining factor for using assisted hatching.
Assisted hatching is not used very frequently and is considered on an individual basis. Please do not submit individual or personal questions that pertain to patient care. Duke University Reproductive Endocrinology and Infertility.
