Is it possible to have twins without family history

Some of these factors include:. Twins are a fascinating phenomenon, which is why people are so curious about the genetic connection to conceiving twins. If you suspect that you might have a genetic link to twinning, you may be partially right.

As stated earlier, your genes may play a role when it comes to your chances of conceiving fraternal twins, rather than identical twins. It is important, however, to understand that other factors may increase your chances of having twins. The chances of conceiving fraternal twins are about two times higher for women whose sister or mother had fraternal twins. This is because of the twin gene. Genetics, therefore, should explain an increased presence of fraternal twins in families with a tendency to hyper-ovulation.

There is no way to predict whether you will have twins, even if you have a history of twins in your family. If you want to calculate your chances of having twins, you need to consider the most viable partners that have twins in your family.

Identical twins do not run in families; rather, they are random. There are certainly both risks and rewards with twins. But before you get too carried away with dreaming, try first looking forward to seeing double… with the lines on your pregnancy test. This can help women or….

We have some suggestions on how you can increase your chances of getting a positive result. A new study finds that epidurals do not affect child development in their later years. A fetal arrhythmia is an irregular heart rate — too fast, too slow, or otherwise outside the norm. It's often benign. Postpartum diarrhea after a C-section is normal.

Factors that increase your odds of having twins naturally. Having twins with fertility treatments. How to increase your odds. A woman has a slightly higher chance of having twins if she has a family history of twins.

However, this only applies if conception takes place without the use of fertility treatments. According to the ASRM , women who are themselves nonidentical twins produce twins in around 1 in every 60 births. For men who are nonidentical twins, the chance of conceiving twins is only 1 in every births.

Some people believe that twins can skip a generation, meaning that a person will potentially have twins if one of their grandparents did. However, there is little evidence to support this theory. The ASRM note that the main factor that increases the chance of having twins is the use of fertility treatments. The various types of fertility treatment available increase the likelihood of twins in different ways.

If sperm fertilizes both of these eggs, this can result in twins. To increase the likelihood of success, the healthcare professional may place more than one embryo into the womb. Twins can occur if both embryos implant and develop successfully. The reason for this is that women of this age are more likely than younger women to release more than one egg during their reproductive cycle. If sperm fertilizes two separate eggs, a twin pregnancy can occur.

The ASRM report that nonidentical twins are slightly more common in taller or heavier women than they are in small women. The reasons for this are not clear, but it may be due to better nutrition. Women with a higher body weight may have more resources available for a developing fetus.

In the U. There are many unproven claims about how to increase the likelihood of conceiving twins. Some people advise following specific diets or using certain alternative therapies, but there is no scientific evidence to support these methods.

You may have heard that twins 'skip a generation'. While it's not a blanket true statement, it is actually based on some truth. Here's how: we know that twinning is due to factors on the woman's side, like hyperovulation. But it takes two to make a baby, or babies in our case! This is where the skipping is relevant.

If a man has inherited the hyperovulation gene from his mother, he may pass this gene on to his daughter, but it won't impact on the chances of him conceiving multiples with his own partner. Men, of course, don't ovulate, so the chance of twins or more is up to the woman. The man's daughter, however, having inherited the hyperovulation gene through her father is then more likely to release more than one egg when she ovulates and therefore could conceive fraternal twins.
