Comprehensive Chromosomal Screening (CCS) has opened up the possibility of identifying normal embryos as well as the gender of these embryos.
Using that knowledge, gender preference embryos can be selected to:
- Avoid sex-linked genetic disease
- Achieve a more balanced representation of both genders within a family
Technology only allows us to identify normal embryos and their gender, not the ability to influence the proportion of male or female embryos in a particular cohort. This ability may become possible with the FDA approval of Microsort (currently pending). Microsort technology is designed to isolate particular sperm that carry either the Y or X-chromosome aiding to select the proportion of male or female embryos in any particular IVF fertilization based on gender preference.
