In vitro evaluation of sperm quality
Animal Reproduction Science, 2008 This paper highlights selected laboratory analyses that are currently used to evaluate sperm, and describes why results from these assays do not consistently correlate with sperm fertility. Reasons for the disconnect between the two are due in part to the definition and reliability of the fertility data collected, to the complexity of the spermatozoon ...
