For fraternal twins, the mother's genetics determine the chance of having them (hyperovulation), but the father can pass these genes to his children, who then pass them to their partner, potentially increasing their chance, though it's the woman who ovulates. For identical twins, neither parent determines it; they are a random occurrence from a single egg splitting, with no known hereditary link.
For a given pregnancy, the odds of conceiving fraternal twins are only determined by the mother's genetics, not the father's. Fraternal twins happen when two eggs are simultaneously fertilised instead of just one.
Fraternal twin pregnancies result from hyperovulation of the mother. The father's sperm does not decrease or increase the chance of having twins. Skipping a generation can happen in some cases, depending on whether the twins are boys or girls.
Women between 35 to 40 years of age with 4 or more children are 3 times more likely to have twins than a woman under 20 without children. Maternal height and weight. Non-identical twins are more common in large and tall women than in small women. This may be related more to nutrition than to body size alone.
Age: If you're over the age of 35, you're more likely to release multiple eggs during ovulation. Family history: If your mother's side has a history of fraternal twins, there is a chance you could conceive twins naturally.
What causes you to get pregnant with multiples? A multiple pregnancy means you're pregnant with more than one baby. Multiple pregnancy usually happens when more than one egg is fertilized. It also can happen when one egg is fertilized and then splits into 2 or more embryos that grow into 2 or more babies.
As you get older, the likelihood of conceiving twins increases. The higher rate of twin pregnancy with age is linked to hormones. Researchers have found that as women get older, they produce more follicle-stimulating hormone (FSH). FSH is what encourages the ovaries to produce eggs.
What causes the fertilised egg to separate into two? The exact reason why this happens is still a mystery. Over the years there has been a lot of research and time invested into finding out why some zygotes split into two and others don't. But the truth is we still do not know why.
Natural ways to increase your chances of having a twin pregnancy
Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families. But there are some factors that make having non-identical twins more likely: non-identical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese.
Age: Women 35+ are more likely to release more than one egg in a cycle. History of twins: If you've had fraternal twins before, your chances of having another set are higher. Pregnancy history: The more pregnancies you've had, the higher your odds of twins.
The Early Signs of a Twin Pregnancy
Hyper-ovulation, also known as super-ovulation, is a condition that occurs when a woman releases more than one egg during a menstrual cycle. This phenomenon is typically caused by fertility treatments or hormonal imbalances, and it can increase the likelihood of conceiving twins or multiple pregnancies.
A family history of multiple pregnancy raises the chances of having twins. Older age. People assigned female at birth who are older than 30 have a greater chance of multiple pregnancy. Today, many people assigned female at birth are waiting to have children until later in life.
Twins generally means that they are born at the same time. "But, yes, twins in that they have come from the same batch of embryos, collected from the same treatment cycle. Twins born at a different time – but not a twin pregnancy when they have grown in the womb together."
Identical twins occur when a single fertilized egg splits into two embryos. This is a random event that occurs during the early stages of pregnancy, usually in the first week after conception.
Number of previous pregnancies – the greater the number of pregnancies a woman has already had, the higher her odds of conceiving twins. Heredity – a woman is more likely to conceive fraternal twins if she is a fraternal twin, has already had fraternal twins, or has siblings who are fraternal twins.
At 37, pregnancy is still a viable option for many women. While fertility does decline with age, numerous women at this stage successfully conceive and have healthy pregnancies.
The food you eat also impacts conceiving twins. A study has found that eating a lot of dairy products will lead to conceiving twins. The best foods to increase fertility are citrus fruits, beetroot, matured cheese, liver, cooked tomatoes, beans & lentils, pomegranate, oysters, walnuts, sunflower seeds, and more.
-At around day 5-8, the embryo can split into two resulting in identical twins with separate sacs and one placenta. 👩🍼 -If the embryo splits between day 8-12, this will result in identical twins sharing one sac and placenta.
Potential health complications in a twin pregnancy
Women with twin pregnancies are more likely to have pregnancy health problems and complications like gestational diabetes, pre-eclampsia, premature labour and bleeding. Twins who share a placenta might have extra complications.
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.
