Soy and infertility
It is currently unknown whether soy has a positive or adverse effect on the fertility in women with PCOS. As mentioned, hardly any studies exist involving soy with PCOS and none so far have really examined its affect on ovulation. One study found that 6 g/day of black soybean powder taken for 6 months improved ovulation in women who weren’t ovulating (5). On the other hand, there are many studies available that show that mice treated with genistein had reduced fertility (6). Some studies even suggest early exposure to soy and/or isoflavones like those found in soy-based infant formulas may have long-term effects on reproduction (4). A study in The Journal of the American Medical Association, however, found no difference in a wide range of reproductive problems between those who were fed soy formula and those fed cow milk formula as infants (8).
A review of 7 soy intervention studies done on women using 32-200 mg/day of isoflavones showed increased menstrual cycle length (9). Currently the evidence doesn’t imply that soy prevents ovulation but may delay it.
While much more research is needed, those of you who are trying to become pregnant or struggle with infertility may want to limit your intake of soy.
Bottom line: much more studies need to be conducted on soy consumption as it applies to humans, and with PCOS in particular. Women with PCOS who struggle with infertility, consume few calories or eat a poor diet may want to avoid or limit soy products. Otherwise, a moderate-low intake of soy (once a day or several times a week) can be part of a healthy diet for women with PCOS.
