Similarly, you may ask, can soy increase estrogen levels?
Since soy acts as a natural estrogen, it may help reduce these symptoms. Studies confirm soy's beneficial role in menopause. In a review of 35 studies, soy isoflavone supplements raised estradiol (estrogen) levels in postmenopausal women by 14% ( 13 ).
Likewise, does soy affect progesterone? Daily consumption of the soya diet reduced circulating levels of 17beta-estradiol by 25% (P<0.01, Wilcoxon signed rank test, two-tailed) and of progesterone by 45% (P<0.0001) compared with levels during the home diet period but had no effect on luteinizing hormone or follicle-stimulating hormone.
Additionally, is soy bad for women's hormones?
Many of soy's health benefits have been linked to isoflavones—plant compounds that mimic estrogen. But animal studies suggest that eating large amounts of those estrogenic compounds might reduce fertility in women, trigger premature puberty and disrupt development of fetuses and children.
Does soy increase estrogen in females?
Isoflavones are structurally similar to estrogen, the female hormone, so the thinking has been that eating a soy-rich diet might have some of the same consequences as an increase in estrogen levels. If soy has estrogenic effects, it might be good for the bones, the heart, even the brain — and in men as well as women.
