A two-decade drop in sperm counts.

Several researchers have observed signs of a decline in sperm counts throughout the industrial world recently -- signaling, they suggest, a possible threat to men's fertility (SN: 1/22/94, p.56). In the Feb. 2 New England Journal of Medicine, Jacques Auger of Universite Paris Sud in France and his colleagues report a steady, 20-year drop in the concentration, motility, and percent of normal-shaped sperm among the 1,351 fertile men they studied. This unexplained drop occurred "independent of the age of the men," they add.
