Do lifestyle factors have an impact on sperm morphology?
The assessment of sperm morphology, determined by the cells’ shape and size, is an important part of male fertility testing. Previous research has suggested that only sperm with good sperm morphology are able to make their way to the egg in the woman’s body and fertilise it. Our knowledge of factors that influence sperm size and shape is very limited, yet faced with a diagnosis of poor sperm morphology, many men are concerned to try and identify any factors in their lifestyle that could be causing this. To investigate the effects of lifestyle factors on sperm morphology, a team of UK scientists based at the University of Sheffield (Professor Harry Moore and myself), the University of Manchester (Dr Andrew Povey and Professor Roseanne McNamee), and the University of Alberta (Professor Nicola Cherry), conducted this landmark research.
