About 1 in 3 of all sets of twin births are vaginal births. You may choose to have an elective caesarean, or your doctor may recommend a caesarean section because of potential complications. Even if you plan a vaginal birth, you may end up having an emergency caesarean section due to complications during labour.
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. Let's learn about twins!
Dizygotic or fraternal twins form in the same way that all humans do, by the union of sperm and egg. The explanation for dizygotic twinning lies in the cause of hyperovulation, which is the release of more than one egg in a cycle of ovulation.
If you're 30 or older, you're more likely than younger people to release more than one egg during a menstrual cycle. You have relatives who have had multiples. If you or other people in your family have had fraternal twins, you may be more likely to have twins, too.
A third milestone in a twin pregnancy is 32 weeks to 34 weeks. Babies born then generally have an excellent chance of survival, without any major long-term complications, though they might not have full lung maturity and will need to spend time in the NICU.
Age. According to the Office on Women's Health , women who are aged 30 years or older are more likely to conceive twins. 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.
Factors that increase the chance of twins include: consuming high amounts of dairy foods, being over the age of 30, and conceiving while breastfeeding. Many fertility drugs including Clomid, Gonal-F, and Follistim also increase the odds of 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.
Identical twins are almost always the same sex, although there are some rare exceptions to this rule. Because identical twins occur when a single fertilized egg splits and forms two embryos, each embryo has the same chromosomes (usually, XX for girls or XY for boys).
The quick answer to this question is that, in a twin pregnancy, it is the mother's genes that determine twins. First up, giving birth to identical twins is not genetic, but conceiving fraternal twins is. The mother may have the genetic trait of releasing two eggs in one menstrual cycle.
No.
That's not all, Monga says. Women pregnant with twins complain of more back pain, sleeping difficulties, and heartburn than those who are carrying one child. Being pregnant with twins also carries a higher rate of maternal anemia and a higher rate of postpartum hemorrhage (bleeding) after delivery.
The risks of induction are the same for twins as for single babies. If induced for twins, you are just as likely to have a c-section compared to induction for a single baby.
A little more than half of twin pregnancies end in preterm delivery (before 37 weeks). While 40 weeks is the full gestation period of the average pregnancy, most twin pregnancies are delivered at approximately 36 weeks (range 32-38 weeks depending on the type of twin pregnancy).
It has been widely assumed that there has been an increase in twins over the years, largely attributed to fertility treatments. But the increase in the multiple birth rate means not just more twins, but also higher order multiples, such as triplets, quadruplets and the like.
Being pregnant with multiples doesn't necessarily mean that your pregnancy will be problematic. However, women carrying multiples do have a higher chance of developing complications such as high blood pressure and preterm labor. For this reason, all multiple pregnancies are considered high-risk.
Are twins hereditary? Yes, some types of twins are hereditary, meaning that twins run in families. Heredity on the mother's side ups a couple's odds of conceiving fraternal twins. Fraternal twins are two babies from two different eggs that were released from the ovaries simultaneously.
It shows it's possible to release two… or even three eggs during ovulation. Another 2006 study used ultrasounds on 507 women over one to three cycles. They found that nearly 21% of women had multiple ovulations for at least one cycle.
Superfetation is a phenomenon that occurs when a pregnant woman releases an egg, usually a few weeks into her pregnancy, and it's fertilized and implants in the uterus. The result is two separate pregnancies happening at the same time.
Some say that twins are always hard (yet amazing), while others say they truly didn't find them to be difficult. A few said that the first two months with twins are easy (being in the rose-colored glasses phase), then reality hits from months 3-6 (when the sleep deprivation catches up), then it can get easier again.
Home pregnancy test positive earlier than “normal”
If you get a positive test, especially a really dark positive, days before your period is even due, that may be one of the early signs of twins! The more babies you're carrying, the higher and faster your human chorionic gonadotropin hormone (hCG) rises.
Fraternal Twins: This type of twin set is the most common. This occurs when two different eggs are both fertilized by two different sperm and implant themselves into the uterine wall at the same time. Fraternal twins will both have a different amniotic sac and placenta.
Extreme hunger is more apparent in women who are pregnant with twins, according to health experts, since the body needs more energy in the form of calories to develop two babies than it would for one.
