Internal Fertilisation
The fertilisation which take place inside the female body is called internal fertilisation.
The female animal’s eggs are fertilised by sperm inside her body.The male animal puts his sperm into the female animal’s body.And these sperms then fertilise the eggs inside body.
Type of fertilisation in which the fusion of a male gamete and a female gamete occurs inside the body of the female animal is called internal fertilisation.
For Ex:Humans, cow, dogs, cats, tigers, lions, rabbit, deer, horse, birds, reptiles etc.
External Fertilisation

Reproduction in frog is called in external fertilization because the fusion of male and female gamate take place out side the body of female (WATER)
Whereas in reproduction in hens is called internal reproduction because fusion of male and female gamate take place inside the female body
