Twins are becoming more common primarily due to the rise in older maternal age (women over 35 are more likely to release multiple eggs) and the increased use of assisted reproductive technologies (ART) like IVF, which often involve implanting multiple embryos or stimulating ovulation. These factors, especially ART, significantly boost the chances of conceiving fraternal twins, while later pregnancies also increase the likelihood of both fraternal and identical twins.
One reason is the use of reproductive technologies such as in vitro fertilization (IVF), which have made it possible for many more couples to conceive. During procedures like IVF, multiple eggs can be used at the same time to maximize the chances of a successful pregnancy, which can lead to twin births.
The phenomenon of celebrities having twins can be attributed to several factors: Age and Fertility Treatments: Many celebrities are having children later in life, which increases the likelihood of multiple births. Older women are more likely to release more than one egg during ovulation.
Older moms are more likely to have twins since females over the age of 35 produce more follicle stimulating hormone (FSH)—meaning they may need assistance in getting pregnant. Some studies have found that women of African-American descent are slightly more likely to carry twins.
One of Africa's largest countries, Nigeria, has been nicknamed “The Land of Twins” by the BBC because it has the highest rate of twin births in the world. In Igbo Ora, in Oyo State in south west Nigeria, the rate is much higher, the last recorded figures revealed an average of 50 sets of twins in every 1,000 births.
Race. African-American people assigned female at birth are more likely to have twins than any other race. Asian Americans and Native Americans have the lowest rates for twins. White people assigned female at birth have the highest rate of higher-order multiple births (triplets or more).
The Nigerian town of Igbo-Ora is famous as the world's ''capital'' of twins due to its unusually high number of twins, from the youngest babies to the elderly.
The gene for hyperovulation can come from either side of the family, but the woman would need to have the gene in order for the couple to have twins based on genetics. In other words, twins on the father's side of the family will have no influence on your chances of having 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.
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.
stated that a research study found that women, on average, could have around 15 babies in their lifetime.
For a given pregnancy, the odds of conceiving fraternal twins are only determined by the mother's genetics, not the father's.
Bible verses about twins
Ecclesiastes 4:9-12 “Two are better than one, because they have a good return for their labor. If they stumble, the first will lift up his friend—but woe to anyone who is alone when he falls and there is no one to help him get up.
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.
You may experience more nausea or fatigue and notice some additional symptoms that singleton pregnancies don't typically present. According to the American Pregnancy Association, these other symptoms may be indicators of twins: More than one heartbeat detected by a Doppler. Increased hCG levels in the body.
Statistics show twins or higher order multiples can take longer to reach milestones, especially those born prematurely. With the average pregnancy usually lasting 40 weeks, if twins were born at 35 weeks, their progress and milestones will be monitored as though they were five weeks younger than they really are.
At 20 weeks of pregnancy, a female fetus has 6–7 million of eggs. By the time the woman is 30 years, she will have lost nearly 90% of her eggs and at the age of 40 years, only around 3% of eggs are left. Most women are no longer able to become naturally pregnant in their mid-40s.
The risks of miscarriage and stillbirth are higher in people who are older than 35. Also, multiple pregnancy is more common when you are older. As the ovaries age, they are more likely to release more than one egg each month. Some fertility treatments also increase the chance of a multiple pregnancy.
You may want help to decide when to go to the birthing center. Traditionally the 5-1-1 rule is used`; that is, when contractions come every 5 minutes, each lasting a full minute, and have been that way for an hour.
Can siblings share more than 50 percent of their DNA? Research has shown that full siblings can share as little as 37 percent or as much as 65 percent of their genetic variants. Do twins share the same DNA? Identical twins are the only siblings who share 100 percent of their DNA.
Nobody knows what causes identical (monozygotic) twins. Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families.
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.
This is largely attributed to the Yoruba people, who have the highest twinning rates globally, possibly due to genetic factors or the high consumption of a specific yam containing phytoestrogens that may stimulate ovulation. Nadiv Moledet To complicate matters there was a place called Benin in pre- colonial Africa.
Percy Nylander clarified many of the factors that contribute to this high incidence of twinning. His analyses of Nigerian placentation and zygosity have shown the increased rate of multiple pregnancy to be a result of higher proportions of dizygotic twins and trizygotic triplets as compared to Caucasian populations.
Other factors that have greatly raised the multiple birth rate in recent years are reproductive technologies, such as: Ovulation-stimulating medicines. These include clomiphene citrate and follicle stimulating hormone (FSH). These help produce many eggs.
