is there a higher chance of twins with ivf?

Statistically, women who undergo IVF have multiple pregnancies (twins, triplets, or higher-order multiples) at a higher rate than women who conceived naturally: According to statistics published in 2013, around 40% of all IVF pregnancies in the US resulted in multiple births.

Identical twins occurs when one egg is fertilized by one sperm, but the resulting embryo splits into two embryos. "Artificial insemination (IUI) procedures increase the risk of fraternal twins by increasing the number of eggs and sperm in the uterus at the same time," Maguire explains.

Yes. Given the nature of fertility treatments, the chances of multiple births while undergoing assisted reproduction procedures tends to be higher than natural pregnancies. The combination of washed sperm and fertility drugs means a greater chance of multiple eggs being fertilized during an IUI cycle.

The study found that the chance of having a baby through further cycles of IVF was 10% higher for women who had previously suffered a miscarriage, than for those who had not become pregnant.

The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births.

Every mature sized follicle could release an egg, and that egg could become fertilized. If you have two follicles, you could conceive twins.

The chance of a single embryo dividing and resulting in identical twins is higher after IVF than after natural conception. So it is possible to end up with identical twins from a single transferred embryo.

"Are IVF babies fertile?" Yes. The incidence of subfertility in adults born as a result of IVF does not seem to be increased.

Women who are over age 30 — especially women in their late 30s — have a greater chance of having twins. That's because they're more likely to release more than one egg during ovulation than younger women. Mothers between ages 35 and 40 who already have given birth have an even higher chance of conceiving twins.

Meet the twins born 2 YEARS apart: Siblings were conceived at the same time using IVF before embryo was frozen. They're difference in size means they don't look much like twins.

Only one ovulation can happen per cycle. You can, however, ovulate two (or more) eggs at the same time. When this happens, there is the potential to conceive fraternal (non-identical) twins if both eggs are fertilized. But having two separate eggs released at different times within the same cycle doesn't happen.

The chances of having identical twins is relatively rare: 3 or 4 per every 1,000 births. Fraternal twins result when two different eggs are fertilized, each by a different sperm cell. This can happen when a woman produces several eggs (most often two) at the same time. This is called hyperovulation.

Multiple births can develop through in vitro fertilization when more than one embryo is put back into the mother's womb. Identical twins can develop even when only one embryo is put back into the womb. Click here to learn exactly how the IVF process works.

If the twins are present on your husband's/partner's side, it won't influence your chances of having twins. Remember, the gene for hyperovulation is only a factor for the mother. If your mother (or your grandmother or aunt) was or had fraternal twins, you might have the gene.

Pregnancies arising from IVF are often thought to be at higher risk than spontaneously conceived pregnancies, but this perception has arisen because of the high rate of multiple pregnancies and associated risks of prematurity that characterized IVF in its early days.

For the average person it would increase probably from 1 in 85 to 1 in 50 pregnancies. If you were an identical twins or you previously had identical twins then the risk is still the same, it's 1 in 250. Your chance of having twins is not increased because you are an identical twin.

“Because conceiving is hard and the baby is treated as precious, so to avoid any complication, doctors may induce a slightly early delivery,” he says. It is also common knowledge that often in IVF cycles, there is a multiple embryo transfer that result in twins and triplets.
