Clomiphene and gonadotropins are commonly used fertility drugs that can increase your chances of having twins. Clomiphene is a medication available only through prescription. In the United States, the brand names for the drug are Clomid and Serophene.
This is why fraternal twins run in families. However, only women ovulate. So, the mother's genes control this and the fathers don't. This is why having a background of twins in the family matters only if it is on the mother's side.
Identical twins are identical, right? After all, they derive from just one fertilized egg, which contains one set of genetic instructions, or genome, formed from combining the chromosomes of mother and father. But experience shows that identical twins are rarely completely the same.
If you were an identical twins or you previously had identical twins then the risk is still the same, it's 1 in 250. Your chance of having twins is not increased because you are an identical twin. Here are the odds of having twins: 1 in 85 in general.
Twin pregnancies have a higher risk for prematurity, which means birth that occurs after 20 weeks but before 37 weeks gestation. Just 40% of twin pregnancies go full term. The average twin pregnancy is 35 weeks, compared to the average singleton pregnancy, which is 39 weeks.
Identical twins form when one egg has been fertilised by one sperm and the zygote splits into two. This happens at the very earliest stage of development, when the zygote is no more than a cluster of a few cells. If this egg then splits into two, an identical twin pregnancy can result.
For every 20 pregnancies conceived with Clomid, only one will result in twins. Clomid (clomiphene), a pill taken by mouth to induce ovulation, causes twin pregnancies between 5% and 12% of the time. 1? That's fewer than one in 10 pregnancies.
So experts say that all women who are able to get pregnant should take a daily supplement that has 400 to 800 mcg of folic acid. Some women need even higher doses. Women who are pregnant with twins or more should take 1000 mcg a day.
In other words, a tall woman with a family history of fraternal twins is more likely to conceive twins during fertility treatments than a short woman without any family history of twins. A young woman with healthier eggs is more likely to conceive twins than a woman over 40, whose egg quality is poor.
Pregnant women who take the recommended folic acid supplements may be more likely to have twins, say researchers in Sweden. The supplements cut the risk of birth defects, but twins have their own problems – they are more likely to be premature, have low birth weights and suffer from cerebral palsy.
It is impossible to definitively know whether you are carrying twins (or multiple babies) by simply gauging how you feel or going off of what a home pregnancy test shows. In fact, only an ultrasound can confirm a twin or multiple pregnancy.
In general, it is fraternal (dizygotic or DZ) twins that run in families. Identical twins don't generally run in families, but fraternal twins do. It looks like twins “skip a generation” in some families. This is because genetic factors that may cause hyperovulation resulting in DZ twins can only be observed in women.
It's a fact that women who naturally conceive twins tend to live in areas where sweet potatoes/yams are a major part of their diet. Yams are supposed to increase the fertility of a woman and improve the ovulation process as well, thereby increasing the chances of getting twins.
If you're wondering how to increase your chances of getting pregnant with twins, try these natural ways:
- Delay Your Next Pregnancy.
- Try to Conceive While Breastfeeding.
- Increase Your Consumption of Dairy Products.
- Ask Your Partner to Consume Zinc-Rich Foods.
- Eat Protein-Rich Foods.
- Take Folic Acid Supplements.
- Sex Positions.
As of 2003, there are on average around 16 sets of twins born per 1,000 births in the United States. It is estimated that 1 in 250 natural pregnancies will naturally result in twins. While twin pregnancies can happen by chance, there are some factors that may increase your odds of having two babies at the same time.
How to Get Pregnant with Triplets?
- Consume a nutritious diet rich in yams, milk, and dairy products.
- The only possible way to increase your chances of having triplets is to have lots of intercourse during your high sex-drive years.
- Eat foods that stimulate progesterone production such as almonds, walnuts, chicken, eggs, and whole grains.
Taking a prenatal vitamin with the recommended 400 micrograms (mcg) of folic acid before and during pregnancy can help prevent birth defects of your baby's brain and spinal cord. Take it every day and go ahead and have a bowl of fortified cereal, too.
Here are 7 Tips to Improve Egg Quality and Boost Fertility
- Stay Away from Cigarettes. Smoking permanently speeds up egg loss in the ovaries.
- Manage Stress.
- Eat Healthy.
- Achieve a Normal BMI (body mass index).
- Boost Blood Flow.
- Invest in Supplements.
- Freeze Your Eggs.
Such a long interval between twins is rare, but not unheard of. (The world record — twins born 87 days apart — was set in 2012). But it's not just the separate birthdays that set these twins apart — it's the fact that each one gestated in a separate womb.
Although two fetuses develop simultaneously in superfetation, they differ in maturity, having been conceived days or even weeks apart. Superfetation is suspected only when the twins are of different sizes and at different stages of development. It is typically noticed during a routine checkup on the ultrasound.
In a twin pregnancy, there are elevated levels of hCG, making it possible to have a very early positive result. However, home pregnancy tests won't confirm if twins are present, only the presence of hCG. It takes around 2 weeks after conception for hCG to be detected in a hCG pregnancy test.
In prenatal ultrasounds, the baby positioned lowest in the uterus is given the designation of “Baby A.” Under this convention, Baby A will likely be born first in a vaginal delivery. However, about 75 percent of twins are delivered by cesarean section.

Boy-girl twins are the most common kind of dizygotic twins, occurring 50 percent of the time. Girl-girl twins are the second most common occurrence. Boy-boy twins are the least common.
In case of a twin pregnancy, babies quickly run out of space in the womb. You will also be able to detect individual kicks, elbow jabs, punches, or a pressing sensation in your abdomen as the babies move around in a limited space.
Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into 2. If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes.
Many couples find out their baby's gender at the fetal survey appointment, which is around 20 weeks. Some expectant moms can find out sooner if your baby is cooperating and a good ultrasonographer takes an ultrasound as early as 16 weeks. “The ultrasound machines are phenomenal, how clear it is.
