NEW YORK (Reuters Health) - A new study has found a "substantial" drop in U.S. men's testosterone levels since the 1980s, but the reasons for the decline remain unclear. This trend also does not appear to be related to age.


The average levels of the male hormone dropped by 1 percent a year, Dr. Thomas Travison and colleagues from the New England Research Institutes in Watertown, Massachusetts, found. This means that, for example, a 65-year-old man in 2002 would have testosterone levels 15 percent lower than those of a 65-year-old in 1987. This also means that a greater proportion of men in 2002 would have had below-normal testosterone levels than in 1987.

The cause is not clear, but I will speculate that it's the chemicals.


I also believe this is why the LGQBTPPPEEE is growing.
