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 GAID:393 UBERON:0001300 FMA:18252 UMLS:C0036471 EMAPA:19296 galen:Scrotum Wikipedia:Scrotum In humans and some other mammals, the base of the scrotum becomes covered with pubic hair at puberty NCIT:C12785 The scrotum of marsupials is not homologous with the scrotum of mammals[ISBN:113945742X] In marsupials, the scrotum is not homologous to the eutherian scrotum, and development is under the control of X-linked genes, not androgens The external sac of skin that encloses the testes. It is an extension of the abdomen, and in placentals is located between the penis and anus.
