It seems that fertility in North American men has taken a serious dip lately, according to a new sperm count research.
Hagai Levine led the research at the Hebrew University of Jerusalem. He and his team systematically reviewed 185 studies of sperm counts in just under 43,000 men.
Using sperm concentration and total sperm count as the primary variables, Levine found that sperm concentration among men in North America, Europe, and Australia declined significantly between 1973 and 2011.
Ultimately, the researchers found that men in those areas had 52.4% fewer sperm than back in 1973. That’s a drastic change considering only 38 years – about 2 generations, had passed.
The reason for the sharp decline isn’t clear, but “research on the causes of this continuing decline is urgently needed.”
If you are really keen on knowing your results, we just discovered there is a smartphone microscope commercially available in Japan to do some self-testing – but only if you’re into that sort of thing.
