Hi Annabel,

Just done some research and yes some phytoestrogens do bind to SHBG but not all. Phytoestrogens also increase SHBG because they act like estrogens.

Thank you very much for your reply, and please accept my apologies for muscling in on your thread, but SHBG was on my mind at the time. It seems from the references you have found that whether or not miroestrol or deoxymiroestrol is bound, PM contains phytoestrogens that are bound and is thus probably unlikely to do other than produce some possibly slight increase in SHBG.

Hi Annabel,

It's good to ask question! How else do we learn.

Phytoestrogens are plant-derived estrogen not generated within the endocrine system but consumed by eating phytoestrogenic plants.

Miroestrol or deoxymiroestrol do bind to SHBG. The phytoestrogens in Pueraria mirifica including miroestrol, deoxymiroestrol, daidzein, genistin, genistein, β-sitosterol, stigmasterol, coumestrol, pueraria, campesterol, mirificoumestan, kwakhurin, and mirificine.

All phytoestrogens have an estrongenic effect to differing extents.

Any thing that act like estrogen will cause an increase in SHBG.
