You’ve probably heard stories about IVF resulting in numerous pregnancies but does it matter? In this article, you will learn more about the science behind IVF and multiple pregnancies, as well as if IVF makes twins more likely than natural conception. But first, let’s discuss twins and what factors can boost the likelihood of multiple pregnancies naturally. IVF twins? keep reading.
Types of Twins
A single egg is fertilized by a single sperm in identical twins. The fertilized egg splits into two along the route, resulting in identical twins. Having identical twins is a rare occurrence, with only 3 or 4 in every 1,000 births. While it may seem obvious, identical twins are always the same sex at birth, whether they are both boys or girls.
They not only have the same appearance, but they also have the same DNA.
When two different eggs are fertilized by two separate sperm cells, fraternal twins are produced. Both fertilized eggs are implanted in the uterus, and two infants are born 9 months later. Two boys, two girls, or a boy and a girl can be fraternal twins. They may or may not resemble each other.
This is because, unlike identical twins, they do not have the same DNA. Aside from their age, they’re no more alike than brothers and sisters who were born years apart.
Natural Consequences of Having Twins
Hyperovulation due to a genetic mutation. Hyperovulation, or the release of two or more eggs during ovulation, is a condition that can be passed down in your DNA from your mother’s genes – or even your father’s.
Twins are more likely to be conceived in women over 35. As you approach menopause, hormonal changes may stimulate your body to release more than one egg during ovulation.
Taller women appear to have a higher rate of twin births. While this may seem weird, experts believe that a certain insulin-like growth factor is to blame.
According to US birth statistics from 2018, black women deliver twins at a higher rate than white women. However, Asian and Hispanic women had a lower rate of twin births than the other ethnicities.
Having twins is more likely if you’ve had previous pregnancies. Women aged 35 to 40 who have four or more children are three times more likely to produce twins than women under the age of 20 who have never had children.
Do I Stand A Chance Of Having Twins Through IVF?
IVF, or in vitro fertilization, does not always result in a significantly increased chance of multiple pregnancies. Women who have IVF have a higher rate of multiple pregnancies (twins, triplets, or more) than women who conceive naturally.
In IVF with fresh embryos, the rate of twin pregnancies is 12.1 percent for women under 35 and 9.1 percent for women 35 to 37, compared to a natural occurrence rate of 2% in the general population.
The chances of twin pregnancy decline with age (unlike natural twin conception), with only a 5.3 percent likelihood of twins being born through IVF in women aged 38 to 40.
And those aged 43 and up had a rate of only 0.5 percent. The practice of transferring more than one embryo at a time in an IVF cycle is the key explanation for the seemingly greater occurrence rate of twins with IVF.
Most fertility experts used to routinely transfer numerous embryos in the hopes of increasing the chances of a successful pregnancy. It was anticipated that implanting two or more embryos at once into the uterus would enhance pregnancy rates, with the expectation that at least one would survive.
Multiple embryos frequently implant successfully, resulting in multiple pregnancies. Some couples decide to transfer only one of their children. While the single embryo may split and produce identical twins, this is unlikely.
For those who choose to transfer two embryos through IVF, say one of them splits and all three implant in the uterus in a similar, less likely scenario.
Triplets – two identical twins and one fraternal sibling – would be the result.
What You Should Have In Mind Regarding Multiple Pregnancies
While having twins sounds like the kind of two-for-one deal that any couple would adore, especially after enduring infertility, it is preferable to have just one healthy baby.
Preeclampsia, gestational diabetes, intrauterine growth restriction (IUGR), placental abruption, fetal demise/loss, increased rates of Cesarean birth, premature labor or delivery, and low birth weights are among concerns associated with many pregnancies and births.
With careful monitoring and single-embryo transfer during IVF, your doctor can limit the chances of multiples.
