In sexual reproduction, a sperm and egg cell unite to form the first cell of the new offspring.
Organisms that have both eggs and sperm are said to be hermaphroditic. This means they have the reproductive organs of both sexes.
sperm and eggs/ovaries
genes
We get organisms because eggs and sperm unite to form embryos, usually. Although some organisms form from spores or cell division.
External. In most cases, adults release sperm and eggs into the surrounding water, where the (unprotected) eggs are fertilized and mature into new organisms.
No, consuming a man's sperm is not beneficial for your health.

No, girls do not have sperm. Sperm are the male's reproductive cells. Only men have sperm. Girls (females) have eggs instead.
No, eggs are not motile. They are typically stationary and rely on external factors like water flow or other organisms for movement. In the context of reproduction, sperm are the motile gametes that swim towards the egg for fertilization to occur.
No, human sperm cannot fertilize goldfish eggs. Sperm and eggs from different species are not compatible for fertilization due to genetic and biological differences.
In the cells that will divide to become eggs or sperm (or the eggs or sperm themselves).
Parthenogenesis is a type of asexual reproduction where organisms can reproduce without their eggs being fertilized by sperm. This is common in species such as reptiles, insects, and fish.
