What do we call the process where a female lays eggs, which are then fertilized by a male outside the female's body?

The process where a female lays eggs and these eggs are then fertilized by a male outside the female's body is known as external fertilisation. This reproductive strategy is commonly observed in various aquatic animals, such as many fish and amphibians, where eggs and sperm are released into the water simultaneously, allowing for fertilization to occur externally.

External fertilisation offers several advantages, including the potential for a large number of offspring produced at one time, which can increase the chances of species survival. This method differs distinctly from internal fertilisation, where the sperm fertilizes the eggs inside the female's body. Implantation refers to the embedding of a fertilized egg within the uterine lining, typically seen in mammals, and budding is a form of asexual reproduction observed in some invertebrates, which involves the formation of new individuals from a parent organism.
