The Andrology Laboratories Committee will present a unique, laboratory-based training workshop with "hands-on" exploration of virtual smears for sperm morphology assessments at the 2008 American Society of Andrology Meeting. The Workshop will teach the two most popular morphology schemes used by fertility specialists today: the WHO 3rd Edition, based on a traditional classification of normal sperm morphology, and Strict Criteria, as described by lab scientists in Tygerberg and in the WHO 4th Edition, where normal is defined according to very stringent criteria.
