    Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. [1] The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the 19th century. [2]

    en.wikipedia.org/wiki/Human_embryonic_development

    In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Fertilization occurs when the sperm cell successfully enters and fuses with an egg cell (ovum). The genetic material of the sperm and egg then combine to form the single cell zygote and the germinal stage of development commences.

    Diagram of stages of developing blastocyst in the human until implantation. There are two stages of migration involved in implantation, the first is the migration of the zygote, and the second is the migration of the trophoblast. [13] Fertilization of the oocyte, takes place in the ampulla of the fallopian tube.

  9. Ovulation - Wikipedia

    en.wikipedia.org/wiki/Ovulation

    Meiosis II follows at once but will be arrested in the metaphase and will so remain until fertilization. The spindle apparatus of the second meiotic division appears at the time of ovulation. If no fertilization occurs, the oocyte will degenerate between 12 and 24 hours after ovulation. [18] Approximately 1–2% of ovulations release more than ...
