    Identical twins: One sperm cell, one egg. Egg splits into two embryos. Triplets, the same.
    Fraternal: Two eggs, two sperms, two different embryos.

  • What happens to those millions of sperm which failed to fertilise?

    They die and are either absorbed in the uterus or are expelled. I'm not sure. I doubt if that question has ever been asked in all of history.

  • And then what happens to them? Does the woman have the mechanism to deal with them?

    Basically the woman's body removes them in several ways just a our bodies defend against a bacteria or virus.  Mucus layers and the immune system. Of about 200,000 only 200 will even reach the egg.

  • The egg splitting is something I need to look into further. The whole biology of reproduction is fascinating.

    It starts with dinner when two people are feeling a bit Randy.  Wine, dinner and the evening progress's.  Viola the EPT stick about a month later shows you got lucky, or unlucky depending on ones point of view.

    You either have multiple eggs meeting with sperm, or the egg splits into twos or threes.  Your first clue is the meeting with the Ob and the ultra sound. We had the two eggs meeting the sperm.......

    Alternative method is the Petri Dish conception and implanting multiple eggs hoping one sticks to the womb, in a lot of cases multiple eggs stick.
