Why does he say that ? Does he come froma family of twins?
Non identical twins do have an increased probability - but it has to pass through the females, as they happen as a rsult of double ovulation. (So your dh may pass that susceptibility on to any of your offspring - but can't force you to double ovulate !)
If he comes from a line of identical twins, then I suppose there may be a genetic basis in a slight increase in the probability of the embryo splitting - but definitely not as high as 95%!
Left handers (don't know why) and older mothers (probably double ovulation, as ovualtion becomes less predictable )are also supposed to increase the odds - but only very slightly.
thats the thing i couldn't understand, he does come from a bid family that carries identical twins. he foung out the info from when he went to have a sperm test. is there any chance of conceiving twins even if its on my side (we have no twins in our family) x
