Most mammals use sexual reproduction, where fertilization is internal, and give live birth.
Some mammals are oviparous (egg laying) mammals called monotremes, namely platypuses and echidnas -- the young are not born live but are nursed after they hatch.
Pouched mammals and placental mammals give birth to tiny young ones, so are called viviparous.
