Men With And Without Obesity May Have Differences In Sperm Protein, Study Indicates

reports “an analysis of sperm from men who were part of a couple whose partner was undergoing in-vitro fertilization (IVF) identified differences in samples between” men with and without obesity. In the study published in the Journal of Assisted Reproduction and Genetics, “there were differences in the amounts of 27 proteins contained in the sperm.” However, “the men all had normal sperm concentration, motility, morphology, and DNA fragmentation, which indicates that ‘these changes in obese men with no overt andrological diagnosis…suggests that traditional clinical semen assessments fail to detect important biochemical changes in spermatozoa which may compromise fertility,’ the authors write.” https://www.medscape.com/viewarticle/925200
