Air Pollution May Affect Sperm Quality, Says Study (theguardian.com) 58

Posted by msmash from the closer-look dept.
Air pollution may affect semen quality, specifically sperm motility -- the ability of sperm to swim in the right direction -- according to a new study analysing the sperm of over 30,000 men in China. From a report: The research, published today in the journal JAMA Networks, also suggests that the smaller the size of the polluting particles in the air, the greater the link with poor semen quality. "Our findings suggest that smaller particulate matter size fractions may be more potent than larger fractions in inducing poor sperm motility," wrote the authors of the paper. The researchers believe that these findings highlight yet another reason for the need to reduce exposure to air pollution among men in their reproductive age.

    Perhaps the problem is insulting being the old manly, and the cultural desire to re-gender what manly means today.

      The interest in such therapies may be because movies and pop culture exaggerate body differences these days. Men are shown with bulging muscles and women with DD's. Older shows didn't have that as often. Charlton Heston was considered a "hunk" in his day, but he looks wimpy when shirtless by today's standards.

        You can't buy a house because the prices are based on a feedback loop. Buyers make offers based on the size home loan a bank approves them for, and the loan gets approved if the house meets the appraised value. The appraised value is based on what neighboring homes sold for, which is based on offers that buyers made based on what the bank approved them for and the appraised value of the homes, which is based on the value of what the neighboring homes sold for..

        This happened because we treat homes like a t

          There is undeveloped land out there - and a lot of it is going to be tough to build on (zoning, access, wetlands, offset requirements, etc.), but that may be what you mean by red tape.

          Trouble is, the land is too expensive! They price the land by looking at what the nearest homes sell for, and deducting an amount to cover building a house on it. So it really ends up no cheaper to build it yourself.
