Factors That Influence Of Having Twins

Regardless of whether you can bring forth intimate twins relies upon your qualities. Different components that raise your odds incorporate age over 35 years, a higher BMI, an eating regimen wealthy in dairy items, and numerous pregnancies. IVF is known to climb the odds as well. Do note, in any case, that the components in charge of the origination of indistinguishable twins remain unknown.Even on the off chance that you do have twins, remember that it’s almost certain you’ll have intimate (non-indistinguishable) twins. Indistinguishable twins happen in only 3 to 4 of each 1000 live births, very by chance. Identical twins are bound to be brought about by chance when a prepared egg happens to isolate into two. This outcomes in two children that look about alike since their qualities are practically indistinguishable. Intimate twins, then again, are the aftereffect of two eggs being prepared by two distinctive sperm, bringing about incubation that happens at the same time. As a general rule, they are much the same as two kin who simply happen to be brought into the world together. Here’s a gander at a portion of the components that may impact your odds of imagining twins.

1. Family History Of Twins

As indicated by the Office on Women’s Health, the inclination to have friendly twins may keep running in families. Dizygotic or intimate twins are twice as likely in ladies whose sisters or moms have had brotherly twins. This is because of hereditary elements like hyperovulation, where, during ovulation, the lady discharges more than one egg. Truth be told, researchers have recognized varieties in two qualities, having which builds the odds of considering indistinguishable twins by 29 percent. One of these qualities impacts the generation of follicle animating hormone (FSH) which adds to ovulation and the other potentially impacts the manner in which ovaries respond to FSH. Studies additionally recommend that friendly twin pregnancies might be connected to the dad’s prevalent semen quality.Since indistinguishable twins occur by some coincidence, this isn’t regularly connected to hereditary qualities and doesn’t generally keep running in families. In any case, as the National Institutes of Health clarifies, monozygotic or indistinguishable twins have been found in higher numbers in a sprinkling of families, demonstrating that there could be a hereditary connection too. While the foundations for indistinguishable twinning are as yet not clear, there is a hypothesis that the qualities engaged with cell grip (in staying cells together) could be at play here.

2. African American Ethnicity

Certain ethnic groups are more likely to have twins than others. According to the Twin Project at the University of Texas at Austin, in the United States, African Americans have the most number of twins. The birth rate of twins is nearly 37 per 1000 compared to just 32 in the average population. On the other hand, if you are Latino American/Hispanic, you are less likely to have twins. The average twin birth rate in this ethnic group is just shy of 22 per 1000. Another study on 76 developing countries found that Central Africa has the highest twin birth rate, with Benin topping the national average at 27.9 twins per 1000 live births.

3.Mother’s Height Around 5’5″

If you are taller than the average American woman, you may have a better chance of having twins. A study on 129 twin moms by Gary Steinman, an obstetrician who specializes in multiple births, reveals that all the moms had an average height of 5 feet 5 inches – over an inch more than the average woman in the USA. This has been linked to a hormone called insulin-like growth factor (IGF), which is stimulated by the human growth hormone. IGF in turn increases ovulation. Taller individuals have a higher amount of circulating IGF.

4.Mother’s Age Above 35 Years

CDC data shows that just 2 percent of women aged under 25 have twin births, compared to 5 percent of those aged between 35 and 39 years. As you grow older but remain fertile, your odds of twin births increase even more. Which is why as many as 7 percent of all women aged 40 or more giving birth have had twins. This could be attributed to the increased production of follicle stimulating hormone by women aged 35 and up, resulting in multiple eggs being released during their menstrual cycle.

5.Stopping Birth Control Pills

Another reason being attributed to higher chances of having twins is if you have recently given up hormonal birth control methods – that is, birth control pills. It is suggested that as the body adjusts its hormonal levels after you get off the pill, there’s a higher chance of releasing multiple eggs during ovulation. However, more studies are needed to back this up.

6.Mother’s BMI Above 30

A surprising cause for twin births is maternal body mass index (BMI). As one study found, women who are obese and have a BMI of over 30 are more likely to have fraternal twins.

7.Breastfeeding In Previous Pregnancies

Another interesting find from Steinman’s study is that if you breastfed your babies from previous pregnancies, you have a higher chance of conceiving twins in later pregnancies. And the longer you exclusively breastfeed, the higher the chance of twinning. This again is linked to the high IGF levels in women who breastfeed.

8.Multiple Pregnancies

It gets more interesting! According to the American Pregnancy Association, if you’ve already had many babies, you are more likely to have twins. The causes for this are not fully understood, though. Anecdotal evidence also suggests that having a miscarriage increases the chances of conceiving a twin. While there’s no scientific evidence to back this, it’s possible that the hormonal readjustment following the miscarriage makes the woman release more eggs during ovulation.

9. In-Vitro Fertilization

What has made a bigger difference to overall twinning numbers is the increased use of infertility treatments like in-vitro fertilization (IVF). In fact, the Centers for Disease Control attribute two-thirds of the increase in twin birth rates in the three decades between 1980 and 2009 to use of therapies like IVF and ovulation stimulation medication.

10. High Doses Of Folic Acid And Multivitamins

Taking high doses of folic acid supplements, both before and after conception, is believed to positively influence your chances of having twins. Now, researchers suggest multivitamins could help, too. As one study concluded, the prevalence of twin births was higher in women who took folic acid and multivitamin supplements pre- and post-conception than in those who did not. However, there has also been evidence that taking high doses of multivitamins and folic acid at the preconception or early stages of pregnancy might increase not just the chances of multiple births but also of miscarriages. In any case, high doses have several adverse effects in the long term and you should stick to the recommended 400 mcg folic acid supplementation.
