It depends. Are you talking about humans? 8D Humans use internal fertilization but the disadvantages in external fertilization is that a small number of eggs survive.
internal same like humans
they have external fertilization , PS i learned it in science :P zz this is all wrong...it does NOT use exernal fertilization...external fertilazation is for fish and stuf,but internal is for humans and mamals.
Butterflies reproduce by internal fertilization and not by external fertilization. Butterflies, like most insects, will then lay the eggs and wait for them to hatch.
Internal fertilization is where the egg is fertilized inside the body(such as humans) and external fertilaztion is where the an egg is laid and then fertilized. Such as in fishes!
Internal. Dogs mate through copulation and internal fertilisation, like all mammals (including humans).

Internal.
External takes place outside the female, as with fish eggs on which the male fish places his sperm. Internal fertilization, in plants and animals, takes place within the organism's structures, where the gametes are joined. In humans, in vitro fertilization (i.e. test tube babies) is a form of external fertilization in that it bypasses the normal occurrence in the fallopian tubes, and then directly implants the fertilized egg(s) in the uterus.
Animals like reptiles (ex. snakes, turtles), birds, sharks, and mammals (ex. humans) undergo internal fertilization.Animals like some fish (ex. salmon), hydra, coral, sea urchins, amphibians (ex. frogs) undergo external fertilization.
It limits the amount of offspring being able to be produced at any one time. For example, humans cant walk around with 500 babies in their womb. Another example is that if the species has a threatening disease it is more likely to be spread via internal reproduction than external reprodution
