Estrone and estrone conjugates were measured in the feces of three female pygmy lorises (Nycticebus pygmaeus) throughout estrus, pregnancy, and the postpartum period. Two females gave birth to twins, while the third had a single stillborn. A comparison between the hormonal profiles of these three pr...
