Declarations
:
: Smithsonian Conservation Biology Institute’s Animal Care and Use Committee granted a waiver of the animal care and use approval for that study because testes and ovaries were collected at local veterinary clinics as byproducts from owner-requested routine neutering and spaying. The same applied to the use of ovaries at the Leibniz Institute for Zoo and Wildlife Research (IZW), Berlin, Germany. Ovaries and testes were collected as byproducts from the routine neutering program of the Berlin Animal Shelter.
