Assessment of testicular endocrine function in captive African elephants by measurement of urinary and fecal androgens

Abstract 10.1002/zoo.10034.abs Androgen measurements in urine and/or feces represent a potentially important tool for monitoring testicular endocrine function in the African elephant. To assess the feasibility of this approach, the aims of the present study were to: 1) examine the presence and relative abundance of immunoreactive testosterone (iT) and its 5α-reduced 17-oxometabolite epiandrosterone (iEA) in […]
