Figures of abnormally shaped sperm

Patient charts were reviewed with men contacted and administered an Institutional Review Board IRB -approved telephone questionnaire to ascertain outcomes. After a median follow-up time of 2. Strict morphology should not be used to predict fertilization, pregnancy, or live birth potential. Semen analysis is a critical tool in the assessment of the infertile male; however, the importance of sperm shape, or morphology, is controversial. The ability of sperm morphology to predict in vitro reproductive outcomes was first proposed by Kruger et al. These findings were propagated by a study published in The Lancet 3 that noted in men with an increased proportion of sperm with abnormal morphology, and the likelihood of pregnancy was decreased.

Measurement and significance of sperm morphology

The measurement or evaluation and clinical significance of human sperm morphology has always been and still is a controversial aspect of the semen analysis for the determination of a male's fertility potential. In this review the background of the development of the evaluation criteria for sperm morphology will be discussed. Aspects of criticism on the strict criteria definition and use of the criteria for sperm morphology evaluation will be discussed as well as possible reasons for the decline in normal sperm morphology values and how we can compromise for this phenomenon resulting in the very low normal reference value as published in the WHO manual for the Examination and Processing of Human Semen.
