Pregnancy and STDs – Risks to Mother and Baby

May 11, 2025

The Centers for Disease Control and Prevention (CDC) says sexually transmitted infections (STIs) are a big risk for pregnant women and their babies. Many pregnant women don’t get tested for STIs, which can cause serious health problems.

Pregnant women can get STIs just like anyone else. These infections can lead to preterm labor, low birth weight, and congenital infections. The CDC suggests that pregnant women should get tested for STIs during their prenatal care to reduce these risks.

Key Takeaways

  • Pregnant women are at risk of contracting STIs, which can lead to serious health issues.
  • STIs can cause pregnancy complications, such as preterm labor and low birth weight.
  • The CDC recommends STI testing as part of routine prenatal care.
  • Untreated STIs can result in congenital infections in newborns.
  • Early detection and treatment of STIs are key to preventing long-term health problems.

The Impact of STDs on Maternal and Fetal Health

STDs can harm both the mother and the unborn baby. They can make pregnancy more complicated. If not treated, they can cause serious health problems.

Prevalence of STDs in Pregnant Women

STDs in pregnant women are a big worry for health experts. Many STIs don’t show symptoms. So, it’s key for pregnant women to get tested during prenatal care.

Statistics in the United States

The CDC says STDs are common in pregnant women in the U.S. Chlamydia and gonorrhea are big concerns, mainly among young women who are pregnant.

STDPrevalence RateHealth Risks
ChlamydiaHigh among young pregnant womenPregnancy complications, neonatal conjunctivitis
GonorrheaSignificant among pregnant teensPregnancy loss, neonatal gonococcal ophthalmia
SyphilisVaries geographicallyCongenital syphilis, stilbirth

High-Risk Demographics

Some groups face a higher risk of STDs during pregnancy. These include young women, those with a history of STDs, and women with many sexual partners. They need special care and testing.

How Pregnancy Affects Immune Response to Infections

Pregnancy changes how the body fights off infections, including STDs. This makes women more likely to get sick. If an STD is caught during pregnancy, it can lead to serious health problems.

It’s important to know about STDs during pregnancy. This helps doctors give the right care and prevent problems. By knowing who’s at risk and how pregnancy affects the immune system, doctors can help keep both mom and baby healthy.

Pregnancy and STDs – Risks to Mother and Baby

STDs during pregnancy can harm both the mother and the baby. These infections can cause serious problems for the mother and affect the baby’s growth and health.

Maternal Health Complications

Women with STDs during pregnancy face serious health risks. These risks include immediate problems during pregnancy and long-term health issues.

Immediate Risks During Pregnancy

STDs can lead to health issues for pregnant women, such as:

  • Preterm labor
  • Miscarriage
  • Chorioamnionitis, an infection of the fetal membranes
  • Pregnancy-related complications like preeclampsia

The Centers for Disease Control and Prevention (CDC) says, “Untreated STDs in pregnant women can lead to serious health complications for both the mother and the baby.”

Long-term Health Consequences

STDs can also cause long-term health problems for the mother, including:

  • Increased risk of HIV infection
  • Pelvic inflammatory disease (PID)
  • Infertility issues
  • Chronic pelvic pain

ChlamydiaPreterm labor, MiscarriagePID, Infertility
GonorrheaChorioamnionitis, Preterm laborPID, Chronic pelvic pain
SyphilisMiscarriage, STILLBIRTHBirth defects, Neurological problems

Potential Impacts on Fetal Development

STDs can harm fetal development, leading to congenital infections and birth defects. For example, syphilis can cause congenital syphilis, leading to serious health problems in newborns.

Neonatal Complications and Outcomes

STDs during pregnancy can also affect the baby after birth. Babies born to mothers with STDs may face:

  • Neonatal infections
  • Low birth weight
  • Respiratory distress
  • Long-term developmental delays

A study in the Journal of Infectious Diseases found, “The transmission of STDs from mother to child during pregnancy or childbirth can result in severe health outcomes for the newborn.”

Common STDs Affecting Pregnancy

STDs can greatly affect pregnancy outcomes. It’s vital to catch and treat these infections early. Pregnant women face risks from sexually transmitted diseases, which can harm both the mother and the baby.

Bacterial Infections

Bacterial STDs are a big worry during pregnancy. They can cause serious health problems. Chlamydia, gonorrhea, and syphilis are common examples.

Chlamydia and Pregnancy

Chlamydia is a big problem for pregnant women. If not treated, it can lead to preterm labor and low birth weight. It can also pass to the baby, causing neonatal conjunctivitis or pneumonia.

Gonorrhea Complications

Gonorrhea is another bacterial infection that’s risky during pregnancy. If untreated, it can cause miscarriage, preterm birth, and neonatal infections. This includes a severe eye infection in newborns.

Syphilis and Congenital Transmission

Syphilis is very dangerous during pregnancy. It can pass to the fetus, leading to congenital syphilis. This can cause birth defects, neonatal death, and miscarriage.

Viral Infections

Viral STDs also pose risks during pregnancy. Key viral infections include HIV, herpes, HPV, and hepatitis B.

HIV and Antiretroviral Therapy

HIV is a big worry during pregnancy. It can pass to the baby. But, antiretroviral therapy (ART) can greatly reduce this risk. It’s key for pregnant women to get tested and treated.

Herpes and Delivery Considerations

Herpes simplex virus (HSV) can pass to the newborn during delivery. This can cause neonatal herpes, a serious condition. Women with genital herpes may need a cesarean delivery to lower the risk.

HPV and Pregnancy Outcomes

Human papillomavirus (HPV) is common and usually doesn’t cause big problems during pregnancy. But, some strains can lead to genital warts or cervical abnormalities. Pregnant women with HPV should be closely monitored.

Hepatitis B Management

Hepatitis B virus (HBV) can pass to the newborn during birth. But, hepatitis B immune globulin (HBIG) and the first dose of hepatitis B vaccine at birth can prevent this.

Other Reproductive Tract Infections

Other infections can also affect pregnancy. Trichomoniasis and bacterial vaginosis can increase the risk of preterm labor and other complications.

Pregnant women need thorough prenatal care. This includes screening for STDs to reduce risks and ensure the best outcomes for both mother and baby.

Prevention Strategies for Expectant Parents

Expectant parents can lower the risk of STDs by using effective prevention methods. It’s key to keep both mom and baby healthy.

Pre-Conception STD Screening

Preventing STDs starts with pre-conception screening. This means testing for STDs before pregnancy. Pre-conception care is vital for a healthy pregnancy.

Safe Sex Practices During Pregnancy

Safe sex is a must during pregnancy. Using condoms correctly and consistently helps a lot. It’s also important to talk about STD status with your partner.

Partner Testing and Treatment

Testing and treating partners is key to preventing STDs. If an STD is found, both partners need to be treated to avoid reinfection.

Importance of Simultaneous Treatment

Treating both partners at the same time is important. It helps clear the infection and lowers the risk of problems.

Partner Notification Resources

Telling your partner about an STD can be hard. Partner notification resources offer help and advice.

Lifestyle Modifications to Reduce Risk

Changing your lifestyle can also help. Avoid risky behaviors and stay healthy.

By following these steps, expectant parents can lower STD risks. This helps ensure a healthier pregnancy.

Transmission Routes from Mother to Baby

It’s important to know how STDs spread from mother to baby. This helps prevent infections in newborns.

During Pregnancy (Transplacental)

STDs can pass from mother to fetus through the placenta. This is called transplacental transmission.

Examples of STDs transmitted this way include syphilis and HIV. The risk depends on the STD and when in pregnancy it happens.

During Childbirth

Babies get exposed to their mother’s genital tract during birth. This can be risky if the mother has an STD.

Vaginal vs. Cesarean Delivery Considerations

The delivery method affects the risk of STD transmission. For example, cesarean delivery may lower the risk of HIV transmission. But the exact reduction varies.

STDRisk During Vaginal DeliveryRisk During Cesarean Delivery
ChlamydiaHighLower
GonorrheaHighLower
HIVHighSignificantly Lower

After Birth (Breastfeeding and Close Contact)

STDs can also spread from mother to baby after birth. This happens through breastfeeding and close contact.

STD-Specific Breastfeeding Guidelines

Mothers with certain STDs should think carefully about breastfeeding. For example, mothers with untreated HIV are usually advised not to breastfeed to avoid passing the virus to their baby.

STD Testing During Pregnancy

STD testing during pregnancy is key to keeping both mom and baby healthy. It’s part of prenatal care to catch infections early. This helps prevent them from being passed on to the baby.

Screening Recommendations

The American College of Obstetricians and Gynecologists (ACOG) says to test for STDs at the first visit. This is usually in the first trimester. If you’re at high risk, you might need to be tested again in the third trimester.

Types of Tests Available

There are many tests for STD screening during pregnancy.

Blood Tests

These tests check for infections like HIV, syphilis, and hepatitis.

Urine Tests

Urine tests are used to find chlamydia and gonorrhea.

Swab Tests

Swab tests help diagnose chlamydia, gonorrhea, and trichomoniasis.

Understanding Test Results and Next Steps

It’s important to understand your test results. If you test positive, you need treatment right away. Talk to your healthcare provider about what this means for you and your baby.
