HPV can affect pregnancy in various ways, but most women with HPV have healthy pregnancies. In some cases, HPV may lead to complications such as genital warts, cervical changes, or an increased risk of preterm delivery, but it generally does not directly harm the baby.
How Does HPV Affect Pregnancy? | Managing Risks and Ensuring a Safe Pregnancy
Human papillomavirus (HPV) is a common virus that affects millions of people worldwide. As an expecting mother, it’s natural to worry about how HPV may impact your pregnancy. I remember being concerned about this during my own pregnancy, so I dove deep into research. While most women with HPV will have healthy pregnancies, it’s important to be aware of potential complications. HPV can cause genital warts, lead to abnormal cervical changes, and, in rare cases, increase the risk of preterm delivery. In this article, we’ll explore how HPV affects pregnancy, how to manage the condition, and what steps you can take to ensure a safe and healthy pregnancy.
HPV is one of the most common sexually transmitted infections (STIs) in the world. In fact, many people with HPV are unaware that they have it because it often shows no symptoms. During pregnancy, the focus shifts to how this virus might affect both the mother and the baby. Let’s look at the different ways HPV can impact pregnancy and what you can do to minimize risks.
Understanding HPV and Its Types
Before diving into how HPV affects pregnancy, it’s important to understand what HPV is. There are more than 100 types of HPV, but not all of them cause health problems. Some strains of HPV lead to genital warts, while others are associated with cervical dysplasia (abnormal cells in the cervix) and an increased risk of cervical cancer.
Low-Risk vs. High-Risk HPV Types
- Low-Risk HPV: These types of HPV cause genital warts but do not lead to cancer. Strains such as HPV 6 and HPV 11 fall into this category.
- High-Risk HPV: These types are more concerning as they can cause changes in the cells of the cervix, potentially leading to cervical cancer if left untreated. HPV 16 and HPV 18 are the most common high-risk strains.
How HPV Is Transmitted
HPV is primarily spread through sexual contact, including vaginal, anal, and oral sex. It’s so common that most sexually active individuals will contract it at some point in their lives, often without knowing it, as the body can clear the virus on its own over time.
Table 1: Common Types of HPV and Their Impact
| HPV Type | Risk Level | Possible Health Effects |
| HPV 6, HPV 11 | Low-risk | Genital warts |
| HPV 16, HPV 18 | High-risk | Cervical dysplasia, cervical cancer |
| Other High-Risk HPV | High-risk | Can lead to cancers of the throat, anus, or genitals |
How HPV Affects Pregnancy: Potential Complications
HPV can affect pregnancy in a few different ways, though in most cases, it doesn’t interfere with the baby’s development or cause major complications. However, there are specific risks that pregnant women with HPV should be aware of.
Genital Warts and Pregnancy
One of the most common ways HPV manifests during pregnancy is through the growth of genital warts. These warts may grow larger and multiply due to the hormonal changes that occur during pregnancy. While they don’t pose a direct risk to the baby, they can cause discomfort and, in rare cases, may affect delivery if the warts block the birth canal.
- Managing Genital Warts: Most doctors recommend waiting until after delivery to treat genital warts, but in some cases, they may be removed if they cause significant discomfort or are likely to interfere with delivery.
Cervical Dysplasia and Cancer Risk
High-risk HPV strains can cause cervical dysplasia, which are abnormal changes in the cells of the cervix. During pregnancy, doctors closely monitor women with high-risk HPV through Pap smears or colposcopies to ensure that cervical changes don’t progress into cancer. Pregnancy does not increase the risk of developing cervical cancer, but any abnormal findings may require additional monitoring.
- Treatment During Pregnancy: If mild dysplasia is detected during pregnancy, treatment is usually delayed until after delivery. However, in rare cases where severe dysplasia or cancer is diagnosed, doctors may recommend treatment during pregnancy.
Preterm Labor and Low Birth Weight
There is some evidence to suggest that HPV might increase the risk of preterm labor or low birth weight. However, these complications are not common, and more research is needed to fully understand the connection between HPV and preterm birth.
Table 2: HPV-Related Complications in Pregnancy
| Complication | Description | Risk Level During Pregnancy |
| Genital Warts | Warts may grow larger due to pregnancy hormones | Low risk, may cause discomfort |
| Cervical Dysplasia | Abnormal changes in the cervix | Monitored during pregnancy, rarely treated during |
| Preterm Labor | Potential risk of early labor | Low risk, more research needed |
| Cervical Cancer | Rare but possible | Extremely rare during pregnancy |
Can HPV Be Passed to the Baby?
One of the most common concerns for pregnant women with HPV is whether the virus can be passed to their baby. In most cases, HPV does not pass from mother to baby during pregnancy or delivery. However, in very rare cases, a newborn may contract a condition called recurrent respiratory papillomatosis (RRP), where warts grow in the baby’s throat or airways.
What Is Recurrent Respiratory Papillomatosis (RRP)?
RRP is an extremely rare condition caused by low-risk HPV strains, particularly HPV 6 and 11, which are responsible for genital warts. Babies born to mothers with genital warts have a slightly higher risk of developing this condition, though it is very uncommon. RRP can lead to the growth of non-cancerous tumors in the respiratory tract, which can cause breathing difficulties and may require surgical intervention.
- Preventing Transmission: There is no guaranteed way to prevent the transmission of HPV to a baby during delivery, but the overall risk remains very low. In cases where genital warts are severe, a cesarean section may be recommended to reduce the risk of passing the virus to the baby.
Table 3: Rare HPV Transmission to Babies
| Condition | Description | Risk Level |
| Recurrent Respiratory Papillomatosis (RRP) | Growth of warts in baby’s throat or airways | Extremely rare, caused by low-risk HPV |
| HPV Transmission Risk | HPV is rarely transmitted to the baby | Low risk, even with genital warts |
HPV and Delivery: Should You Have a Cesarean Section?
In most cases, women with HPV can have a vaginal delivery without any complications. Cesarean sections are generally not recommended solely based on an HPV diagnosis. However, there are situations where a C-section may be advised, particularly if genital warts are large enough to obstruct the birth canal.
Vaginal Delivery
Most women with HPV, even those with genital warts, can safely deliver vaginally. The warts themselves usually don’t pose a risk to the baby, and as mentioned earlier, the risk of transmission is very low.
Cesarean Section
A C-section may be recommended if genital warts are large enough to interfere with delivery or if the doctor feels that it will lower the risk of transmitting HPV to the baby. However, in most cases, this is not necessary, and vaginal delivery is considered safe.
Table 4: Delivery Options for Women with HPV
| Delivery Method | When It’s Recommended | Considerations |
| Vaginal Delivery | Most common choice for women with HPV | Low risk of transmission, warts rarely interfere |
| Cesarean Section | Recommended if large genital warts block birth canal | Reduces risk of transmission but not always necessary |
Managing HPV During Pregnancy: What You Can Do
While HPV cannot be cured, there are steps you can take to manage the condition during pregnancy and reduce the risk of complications.
Regular Prenatal Care
One of the most important things you can do during pregnancy is to attend all prenatal checkups. Your doctor will monitor your cervical health closely, especially if you have a history of abnormal Pap smears or cervical dysplasia.
- Pap Smears: Most doctors perform a Pap smear during early pregnancy to check for cervical changes.
- Colposcopy: If abnormal cells are found during a Pap smear, your doctor may recommend a colposcopy, a procedure that uses a special magnifying instrument to examine the cervix.
Discuss Treatment Options with Your Doctor
If you have genital warts or abnormal cervical cells, talk to your doctor about the best treatment options. In many cases, treatment for warts is delayed until after delivery, but your doctor may offer solutions if they’re causing discomfort or are likely to interfere with delivery.
Take Care of Your Immune System
A strong immune system can help your body manage HPV and reduce the risk of complications. Focus on eating a healthy diet, getting plenty of rest, and managing stress during your pregnancy to support your immune health.
