How can you conceive twins?

I think it has to be in the blood line or to see a fertilty specialist. == answer == Older, well-nourished, fertile women are more likely to have fraternal twins naturally. There is nothing that can increase your cances of identical twins. Even IVF cannot guarantee twins as both may not implant. However, talk to any Mum of twins (mine are 18 today) and although they would not be without them they would never wish them on anyone else, they are SUCH hard work when babies. They are 3 times as much work as a single baby.

There are two primary types of twins, Identical and Fraternal.

Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins.

Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
