They lack genetic material or chromosomes. However, accurately evaluating sperm shapes on a wide range of very stringent morphological criteria is a much more difficult task. In regard to standard IVF, this paper found that the majority of the published studies support the findings that decreased strict morphology may have a negative impact on outcomes.
