What are the chances of twins with IVF?

No medical procedure is without risk. While IVF is certainly among the safest procedures, it is no exception to this rule. One of the most common risks associated with this approach has historically been multiple births. The number of embryos transferred during an IVF cycle directly influences the risk of twins or multiples. In the past, the number of embryos transferred was higher and led to an increase in multiple births.

Natural twin rates are at about 2%. Put simply, twins are rare.

Assisted reproductive technologies changed this. Centers for Disease Control (CDC) research found that of infants conceived with ART:

. 43% were twins

. 3% were triplets or higher-order infants

Put another way, while infertility treatments account for up to 3% of all single live births, they may account for up to 50% of twins born and 75% of higher-order multiple births.

What Can Increase the Chances of Having Twins?

Fertility treatments increase the chances of having both fraternal and identical twins, but there are several other factors, such as age, race, and family history, that can increase the chances of having twins: . Heredity: If you’re a twin, or if twins run in your family, you’re slightly more likely to have a set yourself. . History of twins: When you have one set of fraternal twins, you are twice as likely to have another set in subsequent pregnancies. . Age: The older you are, the higher your chances of having fraternal twins or higher-order multiples. One theory is that women aged 35 or older produce more follicle-stimulating hormone (FSH) than younger women. FSH is also the hormone that causes an egg to mature for ovulation each month, and women with excess FSH may release more than one egg in a cycle. Therefore, older women are statistically less likely to get pregnant, but if they do get pregnant, they are more likely to have twins. . Number of pregnancies: The more pregnancies you’ve had, the higher your chances of having twins. . Body type: Fraternal twins are more common in large and tall women than in small women. . Race: Twins are more common among whites and African Americans and less common among Hispanics and Asians.

How Common are Multiple Births?

Multiple births have become more common in recent years as more people use fertility drugs and procedures like IVF to help them get pregnant.

What Are the Signs and Symptoms of Multiple Pregnancy?

The only way to find out if you are carrying more than one baby during pregnancy is through an ultrasound exam with your healthcare provider. During the test, your healthcare provider can look at images of your uterus and confirm how many babies are in there. You may experience more severe symptoms during a multiple pregnancy than with a single pregnancy. These can include: . Vomiting and severe nausea (morning sickness). . Painful or very sensitive breasts . Rapid weight gain in the first trimester of pregnancy. . High levels of human chorionic gonadotropin (hCG) – this hormone is made during pregnancy and is what a pregnancy test shows. . High levels of alpha-fetoprotein in your blood. Apart from ultrasound, your healthcare provider may suspect multiples if more than one heartbeat is detected during a fetal Doppler scan.

What Are the Different Types of Twins?

Twins are either fraternal or identical. . Fraternal twins happen when two sperm fertilize two eggs in one cycle. This creates a separate placenta for each baby. The DNA of fraternal twins is the same as that of siblings of different ages. They may be the same or of different sexes. . Identical twins occur when an embryo splits into two from one egg and one sperm. The twins may share a common or have separate placentas. Identical twins are always of the same sex. Conjoined twins are rare and occur when an identical twin embryo does not completely divide. The babies’ bodies are fused and may share vital organs. Common points of fusion are the abdomen or chest. This can lead to a shared liver or heart.
