There are many factors that influence the chance of you having twins, but it is advantageous to know that in the United States out of every 1,000 births 32 are twin births. Normally you cannot predict twin births, but there is the slight possibility than any woman can give birth to twins. Basically if your body, age, your genetics, the correct sperm and egg meet up there is a pretty good possibility of conceiving twins naturally .
In our society twins are more prevalent due to the use of fertility drugs. Multiple births are a result of this use in more cases than they are not. Most of the twin birth increase of 400% over the past twenty years can be attributed to the use of fertility drugs. The woman who do become pregnant with twins are many times astonished at the fact.
If you are concerned you may be pregnant with twins, you probably have nothing to be concerned about. To relieve your worry, look to your mother's side in the family history. The odds of you having twins are low if there is not an extended history of fraternal or identical twins. This is contingent on the fact you have not in the past had twins yourself.
If you are attempting to have twins, the chances increase as you get older as opposed to when you were younger. Hormones and the release of eggs become just a bit out of sync so this increases your chance of having twins later in your life.
It has been shown that your race can also influence the odds of your having twins naturally. Twin pregnancies occur more with African American woman than woman of the other races. This is not to say you will have twins, just the odds are better if you are an African American female.
Good signs that you have a chance to become pregnant with twins naturally are age, race, and genetics. Even without these indicators there is still a small chance of having twins. Ultimately the correct egg and sperm need to meet along with the right parents to make a twin pregnancy without the use of fertility drugs. If you truly wish to become pregnant with twins having sex further along in the ovulation cycle or by eating yams are methods that many doctors believe will make you more likely to have twins.
Identical and fraternal are the two kinds of twins you could give birth to. Growing in the same amniotic sac, identical twins arise from a single fertilized egg that separated into two pieces. Fraternal twins are produced by the fertilization of two separate eggs. Each egg then grows as if it was a single pregnancy. Normally the type of twin you are likely to have is determined by genetics. But the same as in a single pregnancy a woman may have fraternal or identical twins even with on past instances of twins in the family.
