taxon notes

The scrotum of marsupials is not homologous with the scrotum of mammals[ISBN:113945742X]

In elephants the testes remain in the abdomen

In hedgehogs the testes remain in the inguinal canal

In marsupials, the scrotum is positioned in the caudal area of the abdomen, in the same position as the pouch in females. It has been suggested that the pouch and marsupial scrotum are sexual homologs, but it is more likely they arise from different primordia in the same morphogenetic field

In marsupials, the scrotum is not homologous to the eutherian scrotum, and development is under the control of X-linked genes, not androgens

In humans and some other mammals, the base of the scrotum becomes covered with pubic hair at puberty
