Abstract: Disclosed is a system and device for determining sex of an embryo utilizing a non-invasive grading of early stage embryos (pre-hatching) based upon specific gravity, density and/or estimated weight. The device comprises a drop chamber having a lumen, capable of assessing characteristics of at least one embryo while descending. The system allows 100% recovery of embryos. A processor is further capable of performing assessment of the embryos. The disclosed system supports a wide variety of scenarios for human and animal reproductive technologies and related products and services.
