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.

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

Cohort Study

Animal

2005 Nov

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.

Similar Assertions

This claim is about a compound called 8-prenylnaringenin (found in hops) and how it affects the uterus and uterine lining in rats that had their ovaries removed. The claim says it has very small growth effects on these tissues, and importantly, these effects don't change no matter how much of the compound is given.

A compound called 8-prenylnaringenin (8-PN) was found to fully stop bone loss in rats that had their ovaries removed - these rats are used to study a condition similar to osteoporosis that happens to women after menopause.
