Estrogenicity of captive southern white rhinoceros diets and their association with fertility

Highlights • Captive-born female southern white rhinoceros (SWR) exhibit poor fertility. • We investigated whether developmental exposure to phytoestrogens is a potential cause. • Many components of captive SWR diets are estrogenic. • We found a significant negative correlation between diet estrogen...

Zusammenfassung:Highlights • Captive-born female southern white rhinoceros (SWR) exhibit poor fertility. • We investigated whether developmental exposure to phytoestrogens is a potential cause. • Many components of captive SWR diets are estrogenic. • We found a significant negative correlation between diet estrogenicity and fertility of captive-born female SWR. • Our data suggest feeding low phytoestrogen diets to SWR should be strongly considered.
