    Description“Previous smaller studies have suffered from confounding factors, including the fact that methods of counting sperm in the laboratory might have changed over the years, or that the populations of men being studied might have changed,” says Daniel Brison, at the University of Manchester, UK.

    “This new analysis overcomes those problems by including a large number of studies of varying design and location around the world, to confirm that the decline in sperm counts is likely to be real,” says Brison.

    DescriptionProfessor Daniel Brison, an expert in clinical embryology at Manchester University who was not involved in the review, said the study’s large size meant any debate about whether the decline was happening was probably over.

    He said by including a large number of studies from around the world the researchers had been able to “confirm that the decline in sperm counts is likely to be ‘real’”.

    And Professor Brison added: “The extent of the decline in sperm counts in the Western world revealed in this study is shocking.

    “As the authors point out, this has major implications not just for fertility but for male health and wider public health.

    “An unanswered question is whether the impact of whatever is causing declining sperm counts will be seen in future generations of children via epigenetic or other mechanisms operating in sperm.
    “This study should act as a wake-up call to prompt active research in this area.”
