Hi, Thanks for the query. I understand your concern. Clomid is a drug which leads to stimulate follicular stimulating hormone FSH from pituitary gland .. stimulates maturity of follicle ( higher dose of the medicine can cause maturity of multiple follicles & cause twins/ triplets/ quadruplets & so on) .. These follicles secretes estrogen .. & on full maturity of ovum... estrogen stimulates Leutinizing hormone secretion by pituitary gland which is responsible for ovulation. Soy isoflavone are known to help in estrogen production by body ... & thereby helps ovulation. Somehow it is not proven to influence FSH secretion by pituitary for more follicles to mature... Some how Isoflavones action is unpredictable in this respect... so it s not sure to cause twin or triplet pregnancy like Clomid. In case you are willing for twin pregnancy you should consult a gynecologist & use either clomid or IUI for increased chance of success Thanks.
