Genital Warts During Pregnancy: Can They Be Treated, Do They Harm the Baby?

My pregnant patients usually bring up genital warts with a two-layered fear: their own health and their baby's health. It's possible to ease both, because the picture is far more manageable than commonly believed. In this article I'll honestly explain why genital warts grow during pregnancy, which treatments are safe and which are off-limits, and — the most frequently asked question — the effect on the baby. One note up front: every decision is made jointly with your obstetrician; this article is meant to prepare you for that conversation.

Why do they grow and multiply during pregnancy?

Pregnancy is fertile ground for genital warts, and the reason is physiological: hormonal changes (including some suppression of immunity), increased blood flow to the area, and increased moisture and warmth make it easier for warts to grow and multiply rapidly. Existing small warts can become more prominent, new ones can appear, and a cauliflower-like appearance can become more pronounced. This doesn't mean the condition is "getting worse" — it's a flare-up specific to pregnancy, usually temporary, and it regresses somewhat once the hormonal picture returns to normal after delivery.

Does it harm the baby? The biggest fear

The clear, reassuring answer: the risk of genital warts passing to the baby is very low. Rarely, HPV transmission to the baby during delivery leading to benign growths in the airway (laryngeal papillomatosis) has been reported — but this is a very rare occurrence, and the vast majority of babies born to mothers with genital warts are completely healthy. Because of this rare risk, routine cesarean is not recommended; in other words, genital warts alone are not a reason for a cesarean. The mode of delivery is decided by your obstetrician based on real factors, such as whether the warts are mechanically blocking the birth canal — not automatically because warts are present.

Safe treatments during pregnancy

When treatment is needed (for warts that are growing, causing discomfort, bleeding, or that could affect the birth canal), there are safe options during pregnancy: cryotherapy (freezing — a commonly preferred, safe method in pregnancy), TCA (a controlled chemical agent — suitable on mucosal areas), and carefully applied electrocautery / laser (especially for large or widespread lesions). Timing matters too: some treatments are scheduled for particular stages of pregnancy to reduce risk. The goal is often to keep the warts under control until delivery; completely clearing every lesion during pregnancy isn't always necessary — some can be left until after delivery.

What's off-limits during pregnancy

A clear boundary: some topical medications are not used during pregnancy. Podophyllotoxin and podophyllin are contraindicated in pregnancy. Imiquimod is also generally not recommended during pregnancy (a doctor's decision). So some of the creams I discussed in the medication article are off the table during this period — which is why treatment during pregnancy relies mainly on procedural methods. And of course, herbal and home remedies are (as always) off-limits during pregnancy too — applying a caustic substance to a sensitive area is doubly dangerous during pregnancy.

After delivery: relief for most

The good news comes after delivery for most pregnant women: once the hormonal flare-up subsides, warts regress somewhat, and treating what remains (now that every method is available again) can be planned more comfortably. Treatment is also possible during breastfeeding; the choice of method is adjusted for breastfeeding. In addition, the HPV vaccine, if postponed, can be brought back onto the agenda after delivery. So the picture during pregnancy is a temporary difficulty; a wider range of treatment options opens up after delivery.

Frequently asked questions

I'm pregnant and I've noticed a wart; should I get treated right away?

No need to rush, but don't ignore it either — it should be evaluated together with your obstetrician and us. Some warts are simply monitored; those that grow or cause discomfort are treated with safe methods. We plan the timing together.

Can I have a vaginal delivery?

In most cases, yes — genital warts alone do not require a cesarean. However, if the warts are seriously blocking the birth canal or creating a bleeding risk, your obstetrician will evaluate this. The decision is based on a genuine obstruction, not simply on the presence of warts.

Will it definitely pass to my baby?

No — the risk of transmission is very low, and the vast majority of babies born to mothers with genital warts are completely healthy. There is a rare risk, but it isn't significant enough to justify a routine cesarean.

Can I get treated while breastfeeding?

Yes — procedural methods and breastfeeding-compatible options can be used during breastfeeding. We choose the method based on your breastfeeding status; don't use a cream on your own decision.
