How do multiple births occur in humans?

Well from what I seem to remember there are a variety of ways the situation can happen. Normally the female ovulates every 28 days and only releases one egg into the fallopian tube for fertlisation before the the fertilised egg is embeded in the uterus. However there are rare occassions when more than one egg is released and as each introduction of male sperm should be carrying millions of little tadpoles hell bent on finding the egg, they can both be fertilised.

This is more common when you find twins that are not identical. Ie a boy and a girl. The other way of multiple births occuring naturally is that the fertilised egg splits and then grow as two seperate but identical embryos.

I am not 100% sure about the stats but I think that identical twins are more common than the differing type. Anything over 2 births, I think can be a combination of both of the above situations and you may end up with triplets where two are identical etc. With todays advances in science the other answer is quite simply fertility treatment. I know that there are various examples of mothers giving birth to large "litters" after paying for treatment.

I think you may have heard of the woman in America who had 8 recently, after paying for treatment. I am sure that someone may be able to give you a more detailed scientific answer but I think this sort of sums it up.

I heard that multiple births occur in humans when an egg splits. (i saw some such instances on 2 programs on TLC cable channel; what I saw makes me glad it ain't me).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
