From Philippe Buchet:

Re: Men’s testosterone levels dropping, study says (Nov. 4): Your article speculates that the drop in testosterone levels may be due to rising obesity rates and decline in smoking. I wonder if it might be due to meat consumption? Just this week, a study reported a possible link between elevated risk of breast cancer and higher rates of red meat consumption. . . possibly due to the use of hormones in beef.
