Sperm Morphology in Fertile Men

Abstract

Sperm morphology was assessed in 78 fertile men according to the Düsseldorf classification. There were 30% normal forms on average, which conforms with the new World Health Organization guidelines. This differs from the strict criteria of the Tygerberg group [9] probably due to the fact that these criteria were established under in vitro conditions.
