  • Male Infertility Crisis In US Has Experts Baffled

    Interesting article in Newsweek reporting that a recent meta analysis has found that male sperm count is declining worldwide. Here’s just a snippet of the article. It’s a fascinating discovery and one that bears watching as the studies continue.

    Startling new evidence suggests male infertility may be much worse than it appears. According to Levine and Swan’s work, sperm levels—the most important measurement of male fertility—are declining throughout much of the world, including the U.S. The report, published in late July, reviewed thousands of studies and concluded that sperm concentration had fallen by 52 percent among men in Western countries between 1973 and 2011. Four decades ago, the average Western man had a sperm concentration of 99 million per milliliter. By 2011, that had fallen to 47.1 million. The plummet is alarming because sperm concentrations below 40 million per milliliter are considered below normal and can impair fertility. (The researchers found no significant declines for non-Western men, in part because of a lack of quality data, though other studies have found major drops in countries like China and Japan.) And the decline has grown steeper in recent years, which means that the crisis is deepening. “This is pretty scary,” says Swan, who has long studied reproductive health. “I think we should be very concerned about this trend.”
