Sperm Counts Among Western Men Have Halved In Last 40 Years, Says Study (theguardian.com)

New submitter flote shares a report from The Guardian: Sperm counts among men have more than halved in the last 40 years, research suggests, although the drivers behind the decline remain unclear. The latest findings reveal that between 1973 and 2011, the concentration of sperm in the ejaculate of men in western countries has fallen by an average of 1.4% a year, leading to an overall drop of just over 52%. The study, published in the journal Human Reproduction Update by an international team of researchers, drew on 185 studies conducted between 1973 and 2011, involving almost 43,000 men. The team split the data based on whether the men were from western countries -- including Australia and New Zealand as well as countries in North America and Europe -- or from elsewhere. After accounting for factors including age and how long men had gone without ejaculation, the team found that sperm concentration fell from 99 million per ml in 1973 to 47.1 million per ml in 2011 -- a decline of 52.4% -- among western men unaware of their fertility. For the same group, total sperm count -- the number of sperm in a semen sample -- fell by just under 60%.

    Have they done a study to determine if there has been a balancing increase in sperm production by western women?

    One sperm is enough, doesn't matter if it's 100 or 50 million.

    Heck, my wife gets pregnant if I look at her too long.

    I don't think so. You might want to get a paternity test done on "your" kids.

    Not being able to belch and fart in public, no more wolf-whistling or swearing like a sailor, the cancellation of the Man Show, eating fscking gluten-free vegan yoghurt steak-substitute, and having to get in touch with our "feelings", not only are sperm counts heading for zero, at this rate we're going to start having periods.

    I blame skinny jeans. I've been in boxers and loose pants for decades and have no issues. I see these young beta males running around in skin tight jeans and I just figure they never want kids or something.

    Also, what do you mean by "no guy at all?"

    Possibly you have identified the root cause of the lack of sperm count.

    If the trend continues, there will be a day when Western Man is no longer able to produce sperm at all.

    But fear not, humanity! Thanks to frozen sperm, bulls that died years ago are still fathering calves. With my high IQ and 6' 2" manly-man size, I am willing to contribute now to save First World Man from extinction.
