Do male marsupials have a pouch? Do male marsupials have a pouch, or is it a female organ only (like the womb)?

In most marsupials, only the females have a pouch. However, males of the water opossum and the extinct tasmanian tiger (or thylacine) also have a pouch. The males of both the thylacine and water opposum used/use their pouch to keep their genitalia from getting entangled in vegetation.
