Abnormally high body mass index and tobacco use are associated with poor sperm quality as revealed by reduced sperm binding to hyaluronan-coated slides.

摘要

Responses on a lifestyle questionnaire were correlated with results from traditional semen analysis and a newer functional sperm assay, namely, the ability of sperm to bind to a hyaluronan-coated slide. Increased percent normal morphology and motile sperm concentration were positively correlated with increased HA-binding score, whereas tobacco use (either current or previous history) and abnormally high body mass index were associated with lower binding scores.
