Gut Microbiota and Phytoestrogen-Associated Infertility in Southern White Rhinoceros

Phytoestrogen Metabolism by Adult Human Gut Microbiota.

Phytoestrogens are plant-derived polyphenols with a structure similar to human estrogens. The three main groups of phytoestrogens, isoflavones, ellagitannins, and lignans, are transformed into equol, urolithins, and enterolignans, respectively, by bacteria. These metabolites have more estrogenic/antiestrogenic and antioxidant activities than their precursors, and they are more bioavailable. The...

Patients with type 2 diabetes account for about 90% of people with diabetes. Studies over the past years have shown a significant association between intestinal microbiota, intestinal dysbiosis, and metabolic syndrome. Changes in the...

Fecal corticosterone concentrations and reproductive success in captive female southern white rhinoceros.

Prolonged or frequent secretion of adrenal glucocorticoids in response to aversive stimuli can negatively impact reproduction. Because female southern white rhinoceros (Ceratotherium simum simum) reproduce poorly in captivity, we compared fecal corticosterone metabolite concentrations among parous, nulliparous, and adolescent females and examined social and physical aspects of the captive envir...
