Have a go at boron / borax; it is needed for hormone regulation, and works very well with the Iodine
Balances the sex hormones, increases estrogen. I am very happy for boron!
There are several posts about it at the forum, too.
Make sure you take all the other co-factors with iodine,like magnesium; also important for the hormones (enzyme reactions)
Infertility treatment, you mean medications?
