Fertilisation in kangaroos is an internal process, not external. This is the case with all mammals.
Most mammals fertilize internally. A platypus fertilizes externally.
yes. just like all other mammals . if that egg inside the female does not get fertilized by the male then it becomes break feast for predators . but if your talking about humans then simply goes away

An elephant uses the internal fertilization as the male elephant mounts the female.
both internally and externally.
