Intrauterine pregnancies (IUPs) are the most common type of pregnancy. They happen when a fertilized egg implants in the uterus but doesn’t implant fully. This can happen in either the fallopian tubes or the womb. The risks of having an IUP include – Higher miscarriage rate – More difficult delivery – More frequent c-sections – A higher risk for postpartum depression, and other mental health issues. If you are pregnant and have questions about whether you are having an IUP, please speak with your doctor. There is a lot of information available on the internet, and you must speak with a healthcare professional familiar with intrauterine pregnancy.
What is intrauterine pregnancy?
Intrauterine pregnancy is a condition in which a fertilized egg (the embryo) is located within the uterus (the woman’s womb). Intrauterine pregnancy can occur when a man or woman has sex without using birth control or when birth control fails.
There are two types of intrauterine pregnancy: tubal and ovulatory. Tubal pregnancy occurs when the egg gets stuck in the fallopian tube. Ovulatory intrauterine pregnancy happens when the egg can travel through the cervix and reach the uterus.
Intrauterine pregnancy is classified as high-risk if the fetus has any of these conditions:
- There is a high chance that the baby will have major problems, like Down syndrome, neural tube defects, or heart disease.
- The baby might not live past 24 weeks gestation due to health problems related to being born early.
- The mother might develop a serious complication like ectopic pregnancy (a condition in which the embryo implants outside the uterus), preterm labor, or low birth weight babies.
- The mother might need an emergency C-section to deliver her baby because of health risks posed by intrauterine growth restriction (IUGR)—when there’s too little room inside the uterus for the fetus to grow properly.
- When multiple pregnancies happen together, they are more likely to experience adverse outcomes like premature delivery, low birth weight babies, and plac
The risks of intrauterine pregnancy
Intrauterine pregnancy is a pregnancy that occurs within the uterus or inside the womb. It’s one of the most common types of pregnancy, and it’s also one of the safest. However, intrauterine pregnancy carries its own set of risks. Here are four of them:
- Intrauterine birth defects: A significant risk associated with intrauterine pregnancy is the development of intrauterine birth defects (IBD).
- IBD is a term used to describe any defects in an unborn baby during or after conception, including problems with the heart, spine, eyes, brain, and other organs. Birth defects are particularly common in babies whose mothers have high-stress levels before conception or during early gestation.
- Preterm labor and delivery: Intrauterine pregnancies can also lead to preterm labor and delivery (PTD). PPD is labor that starts before 37 weeks gestation and continues for more than 24 hours without reaching full term (38 weeks). 4
- Pregnancy-related deaths related to PTD account for about 10% of all maternal deaths in the US annually. Premature Delivery Partnership Worldwide estimates that around 1 in 7 births worldwide (~14%) is premature due to intrauterine conditions.5
- Increased risk for developing gestational diabetes: One study found that women who had an intrauterine pregnancy were almost twice as likely to develop gestational diabetes later on in their lives compared to women who didn’t have
How can I prevent intrauterine pregnancy?
Intrauterine pregnancy is when a fertilized egg implants (becomes embedded) in the lining of the uterus but does not become born. There are many potential causes of intrauterine pregnancy, including unprotected sexual activity with an unknown partner, having sex before you are ready, using contraception that does not cover all prevention methods, and undergoing fertility treatments.
Intrauterine pregnancy can be dangerous for both the woman and the fetus. The woman may experience early labor or delivery, high blood pressure, pain during labor and delivery, vaginal bleeding, and risk for preterm birth. The fetus may have health complications such as low birth weight, breathing problems, mental disability, and heart defects.
Treatment for intrauterine pregnancies
Intrauterine pregnancies are when a baby is conceived inside the uterus or womb. They happen in about 1 in every 150 women. Intrauterine pregnancies can be dangerous for both you and your baby. They’re more likely to end in a miscarriage but also carry a higher risk of birth defects, including serious brain and heart difficulties.
There are two main types of intrauterine pregnancies: ectopic and antecedent. Ectopic pregnancies are when the fertilized egg implants outside the uterus (in other words, on top of the bladder, on one of the Fallopian tubes, or even in the woman’s stomach). Antecedent pregnancies are when a woman already has an existing pregnancy (with either eggs or sperm) when she gets pregnant with a baby conceived through intercourse.
The most common reason for an ectopic pregnancy is because the male partner has sex without using contraception. If you have an ectopic pregnancy, your doctor will probably perform surgery to remove the pregnancy. About half of all women who get an ectopic pregnancy will have it terminated by this procedure.
The most common cause of antecedent pregnancies is having unprotected sex right before ovulation (when you’re most likely to get pregnant). About 60% of women who get an antecedent pregnancy will have it terminated by this procedure.
