The Claim

At equivalent bone-protective doses, 8-prenylnaringenin (8-PN) demonstrates approximately 10-fold lower stimulatory effect on uterine and endometrial tissue compared to 17beta-estradiol

Source: Tissue specificity of 8-prenylnaringenin: protection from ovariectomy induced bone loss with minimal trophic effects on the uterus.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

A compound found in hops called 8-prenylnaringenin (8-PN) appears to be much weaker at stimulating the uterus and uterine lining than the hormone estrogen, even when both are given at doses that protect bones equally well.

What the research says

1 study

  1. Study: Tissue specificity of 8-prenylnaringenin: protection from ovariectomy induced bone loss with minimal trophic effects on the uterus.

    The study directly confirms the claim - when researchers gave rats 8-PN at doses that protect bone as well as estrogen does, they found the phyto-estrogen stimulates the uterus about 10 times less than estrogen does. This matches exactly what the claim says.
