Proficiency testing results suggest that the human sperm survival assay is comparable to the mouse embryo bioassay for detection of embryotoxicity. However, more studies are needed to determine the appropriateness of the sperm motility assay as a standard bioassay for human embryo viability and IVF Author: C. Adams, L. Anderson, L. Wheeler, S. Wood.


Testing confirmed that the device in both tube and applicator met all acceptance criteria for appearance, color, odor, viscosity, osmolarity, specific gravity, pH, microbial limits, endotoxin, mouse embryo assay, and human sperm survival assay throughout the entire proposed two year shelf life. Among these bioassays, the human sperm assay (HSA) has been an integral part of IVF since its inception. Edwards and Steptoe, the 2 pioneers of human IVF, utilized HSA for testing the suitability of the solutions and materials used in the first successful IVF pregnancy in the world [1, 9].Cited by: 2.
