A. The cryopreserved sperm that Xytex provides is just as fertile, if not more fertile, than typical freshly ejaculated sperm. Cryopreservation requires careful selection of “freezable” donors, then adding materials to protect the cells from freezing injury, as well as regulating cooling and freezing in such a way to minimize freezing injury. The insemination material in IUI and ICI samples provided by Xytex has no fewer than 30 million motile sperm per milliliter, much “richer” than that provided by other sperm banks. A normal sperm count in a typical “fresh” ejaculate is 20 million sperm per milliliter. Because fewer cells are needed in procedures such as IVF and ICSI, Xytex ART vials have a guarantee of at least 15 million motile sperm per milliliter.
