A prolonged decline in male fertility in the form of sperm concentrations appears to be connected to the use of pesticides, according to a study published Wednesday.

Researchers compiled, rated and reviewed the results of 25 studies of certain pesticides and male fertility and found that men who had been exposed to certain classes of pesticides had significantly lower sperm concentrations. The study, published Wednesday in Environmental Health Perspectives, included data from more than 1,700 men and spanned several decades.

“No matter how we looked at the analysis and results, we saw a persistent association between increasing levels of insecticide and decreases in sperm concentration,” said study author Melissa Perry, who is an environmental epidemiologist and the dean of the College of Public Health at George Mason University. “I would hope this study would get the attention of regulators seeking to make decisions to keep the public safe from inadvertent, unplanned impacts of insecticides.”

      There’s no fda approved male birth control because everything they’ve tried to specifically target fertility has other unacceptable side effects.

      So view this as a canary in a coal mine scenario. This is one aspect of health that’s easy to measure, but without further study we cannot assume that there aren’t other more severe health complications associated with exposure to pesticides.

          Sterilization is not equivalent to birth control. To be considered birth control, fertility should return shortly after the cessation of usage. Since vasectomies are considered permanent it’s not in the same category.

          Although, that’s beside the point, and I’m pretty sure you know it and are being cheeky. The point is if researchers trying to target just fertility with no unwanted adverse health effects have a hard time developing such a drug, then we should assume that it is very likely that substances that cause decreased fertility are also causing other adverse health consequences.

      Depends if the economy can cope with the shrinking labor force and demand. And who is going to take care of all these old people. Unless we have automated a large part of our economy by then either we’d be fucked or the developing nations will be exploited even harder.

      It’s not for countries with shrinking populations. The most sustainable model is a roughly constant population, which we’re going to reach sometime within the next 50 years. A shrinking population means an aging population, which comes with its own host of issues (see: Japan and Korea).
