It is unclear if phytoestrogens have any effect on male physiology, with conflicting results about the potential effects of isoflavones originating from soy. [1] Some studies showed that isoflavone supplementation had a positive effect on sperm concentration, count, or motility, and increased ejaculate volume.

Glycitin (glycitein 7-O-glucoside) is an isoflavone found in soy, and remains to various degrees in soy products like tofu, soymilk [1] and soy sauce. [2] Although glycitin has its own health associated properties (below), it can be transformed to glycitein by human intestinal flora by the action of beta-glucosidases.
Isoflavone differs from flavone (2-phenyl-4H-1-benzopyr-4-one) in location of the phenyl group. Isoflavones are produced via a branch of the general phenylpropanoid pathway that produces flavonoid compounds in higher plants. Soybeans are the most common source of isoflavones in human food; the major isoflavones in soybean are genistein and ...
Glycitein is an O-methylated isoflavone which accounts for 5-10% of the total isoflavones in soy food products. Glycitein is a phytoestrogen with weak estrogenic activity, comparable to that of the other soy isoflavones. [1] Glycitin (glycitein 7-O-glucoside) can be transformed to glycetein by human intestinal flora.
A 2019 systematic review found that intake of soy and soy isoflavones is associated with a lower risk of mortality from gastric, colorectal, breast and lung cancers. [74] The study found that an increase in isoflavone consumption by 10 mg per day was associated with a 7% decrease in risk from all cancers, and an increase in consumption of soy ...

Soy products decrease sperm quality due to the high content of a type of phytoestrogen called isoflavones. [16] [17] Theoretically, this exposure to high levels of phytoestrogen in men may alter the hypothalamic-pituitary-gonadal axis. A few studies on animals have shown that such a hormonal effect may be significant and decrease fertility. [18]
