Not recommended: EPO has been studied in a severe estrogen diminished state such as postmenopause. Available data suggest that it is no more effective than placebo. In the only randomized trial to address this issue 56 symptomatic postmenopausal women were randomly assigned to EPO versus placebo for six months. There was no significant difference in symptoms. And increasing estrogen can exacerbate certain cancers

While I appreciate your citing the literature, the fact that EPO does not help postmenopausal women has no bearing on whether it helps PCOS. The mechanisms via which EPO may help PCOS are related to its effects on prostaglandins and cervical mucous. Research is needed but it is plausible that it might help.

Does not raise E but: EPO does not raise estrogen but may help PCOS by increasing Prostaglandin E and may improve fertility by increasing cervical mucous. It should be balanced with Omega 3 Fatty Acids. There is no good research proving it helps, but none showing it doesn't. It's safe to try.
