the type of reproduction that requires the union of sperm and egg
Human fertilization Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube.[1] The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century.[2]
Egg Reproductive structures similar to the egg in other kingdoms are termed "spores," or in spermatophytes "seeds," or in gametophytes "egg cells".
