ABSTRACT
The predictive values of four categories of established sperm function assays-computer-assisted
semen analysis (CASA), induced-acrosome reaction testing, sperm penetration assay,
and sperm-zona pellucida binding assays-are still unsure. In this article we examine
the evaluation of sperm competence. We propose that assessment of sperm competence
should include investigations at the nuclear, organelle, and cytoskeletal levels.
In light of this, we discuss the assessment of sperm nuclear integrity as an alternative
new method of analysis. We also question the merit of having such tests, whereby it
may be an easier choice to direct these patients straight to an assisted reproduction
treatment.
