Abstract

Aneuploidy is a common cause of poor reproductive outcomes in humans and is associated with severe medical problems in liveborn offspring, yet little is known about its underlying cause. A substantial amount of aneuploidy is known to be contributed by the father through cytogenetically abnormal sperm. The purpose of this cross-sectional, observational study was to investigate the potential contribution of common lifestyle exposures (smoking, caffeine, and alcohol) to the aneuploidy load in sperm from 45 healthy male volunteers 19-35 years of age. Sperm FISH (fluorescence in situ hybridization) was used to determine aneuploidy and diploidy frequencies for chromosomes X, Y and 18 across varying exposure levels of smoking, caffeine, and alcohol. Caffeine was significantly associated with increased frequencies of sperm aneuploidy XX18 and XY18, diploidy XY18-18 and the duplication phenotype YY18-18 controlling for alcohol, smoking and donor age. Alcohol was significantly associated with increased frequencies of sperm aneuploidy XX18, diploidy XY18-18 and the duplication phenotype XX18-18 controlling for caffeine, smoking and donor age. There was a suggestive, but not unstable, association between smoking and XX18. Even within our truncated age range, we were able to confirm an increased risk for XX18 aneuploidy with increasing donor age. Sperm FISH proved to be a useful biomarker to detect and compare numerical cytogenetic abnormalities in human sperm cells across differing levels of exposure to smoking, caffeine, and alcohol.

Interesting...thanks for posting.

I wish there was a chart or info on the rate of increase for mutations vs. age.

Besides advancing paternal age, it would have been interesting to see if the caffeine correlation held when corrected for green/black tea consumption vs. those chemical-laden sugar bombs (Cola drinks!).
