Testosterone and anti-Müllerian-hormone (AMH) in lean and overweight male Labrador Retrievers

Conclusions Serum concentrations of testosterone and AMH did not differ between lean and overweight dogs. This could be due to a lack of real difference, that the sample population was too small and the power of the study thus limited, or that the BCS was too low in the overweight dogs (only mild overweight). The concentration of testosterone, and potentially also AMH, varies throughout the day, but due to the standardised sampling, this should not affect the results.
