GMO foods could make it worse.
Testosterone deficiency is a serious health issue. It can lead to loss of stamina and lean muscle mass, reduced libido in both men and women, anxiety, depression, and cognitive decline. Growing research also suggests low testosterone levels might be linked to insulin resistance, metabolic syndrome, and type 2 diabetes.
Many of the herbicides and pesticides used in conventional farming are “environmental estrogens.” This means that their molecules mimic the activity of the human hormone estrogen, too much of which is not good for men or women; it also affects testosterone levels. Now GMO crops have likely exacerbated this problem. According to a recent animal study published in the journal Toxicology in Vitro, glyphosate (the active ingredient in Roundup, Monsanto’s widely used pesticide) often leaves a residue on Roundup Ready crops—and this can affect testosterone levels and men’s sperm counts. It is actually toxic to testicle cells, and significantly lowers testosterone synthesis.
