TY - JOUR AU - Samplaski, Mary K. PY - 2017 TI - A few more fragments: putting sperm DNA integrity testing into clinical practice JF - Translational Andrology and Urology; Vol 6, Supplement 4 (September 30, 2017): Translational Andrology and Urology (Sperm DNA Fragmentation) Y2 - 2017 KW - N2 - While routine semen analysis has been the cornerstone of the male fertility evaluation, we know that it is far from a perfect predictor of fertility, and there will be some couples who struggle to obtain a live birth despite the male having a normal semen analysis. Indeed, the World Health Organization semen analysis normal reference ranges were based on samples from fertile men (1). The LIFE study, a prospective observational cohort study of 501 couples, which looked at the relationship between routine semen parameters and time to pregnancy, found that on multivariate analysis, none of the routine semen parameters (volume, concentration, motility or morphology) were associated with time to pregnancy. Only male age and female body mass index (BMI) were associated with the time to pregnancy (2). From both this data and others, we know that the standard semen analysis is not a perfect predictor for male infertility (3). These limitations have led to the investigation of sperm DNA fragmentation as an adjunctive test to guide the management of the sub-fertile couple. UR - https://tau.amegroups.org/article/view/15123
