My RE prescribed 75 mg of DHEA. I just grabbed my prescription bottle: CMP-DHEA.
Since starting DHEA, I have had my most successful cycles. Including finally making it to transfer which I hadn't made it to previously (only ER) and a chemical pregnancy from an IUI.
We also found a protocol that is more optimal for me too. In that regard, it's hard to say the exact impact of DHEA versus a better protocol.
