It appears that sperm counts in developed nations are significantly down over the past 10-15 years. Not only are there fewer little guys per load but the quality of them is also below par. What this means for the quality of the people they turn into, I have no idea but one feel that it can’t be great.
For instance, one sperm bank in Israel says that when it opened its doors 1991, it turned away about a third of the applicants for low quality. Using the same standard today, it would reject more than 80 percent, according to an article in the LA Times. And while the jury is still out on whether there is a real “sperm decline” and what that means for fertility, scientists say if the little swimmers are truly changing, it may be a red flag for harmful environmental toxins or even physiological changes in the human body.
It’s hard to tell what is causing this decline but one cant help but look at the way in which we live in the west and wonder. Perhaps we’ll start paying more attention to our sperm, who knows weather or not they’ll be a canary in the coal mine of greater physiological changes in the species.
“Rapid changes in reproductive function may indicate serious changes in our environment, which may be affecting our health in so far undetectable ways,” said Deonandan. So, while the global decline in sperm quality may not stand up to rigorous testing, “it’s definitely worth taking seriously, since it may open the door to deeper insights into other ways in which changes to our environment, behavior and lifestyles are negatively affecting our biologies.”
