Genital warts during pregnancy are usually harmless to the baby and often need no treatment. Several home wart creams aren't safe in pregnancy, so a clinician removes warts in-office when needed, typically by freezing or applying acid. Transmission to a newborn is rare, and a wart diagnosis alone isn't a reason for a cesarean.

Why genital warts matter in pregnancy
Genital warts come from low-risk HPV types, chiefly 6 and 11, which together cause more than 90% of genital warts and do not cause cancer CDC. HPV is the most common STI, and most infections are quiet: in 9 out of 10 cases, HPV clears on its own within two years. Warts are the visible exception, appearing as a small bump or cluster of bumps in the genital area.
Pregnancy changes the picture in one practical way. Higher estrogen and increased blood flow to the genital tissues can make warts grow faster, multiply, or appear for the first time, even in someone who carried the virus quietly for years. After delivery, when hormones settle, they often shrink or regress on their own.
Treatment safety is the other reason this matters. The wart creams many people reach for at home are off-limits in pregnancy, so the approach shifts to in-office removal. The types that cause warts are separate from the high-risk types behind cancer. You can read more about hpv leading to other kinds of cancers, but vaccine does help to reduce cervical cancer, but a wart diagnosis does not mean you have a cancer-causing infection.
Risks to the baby
For the overwhelming majority of newborns, a parent's genital warts cause no problem at all. The virus can pass to a baby around the time of birth, but symptomatic infection is rare.
The condition clinicians watch for is recurrent respiratory papillomatosis (RRP), wart-like growths from HPV 6 or 11 that develop in a child's airway and voice box. These can cause hoarseness or breathing trouble and may need repeated procedures to keep the airway clear. RRP is uncommon, and a planned cesarean does not reliably prevent it because the virus can be encountered before delivery, so a wart diagnosis by itself isn't a reason to schedule a C-section.
Very large warts are a different conversation. If warts grow big enough to block the birth canal or are likely to bleed heavily during a vaginal delivery, a clinician may recommend a cesarean for those mechanical reasons rather than to protect the baby from the virus. That decision is individual and made with your obstetric team.
Screening and diagnosis in pregnancy
Genital warts are diagnosed by sight. A clinician examines the bumps, and biopsy is reserved for atypical or uncertain lesions. There's no separate "wart test," and swabbing warts for HPV type adds nothing, since the diagnosis is visual and the treatment is the same.
Cervical cancer screening continues on its usual schedule during pregnancy and is not for warts. It looks for high-risk HPV and precancerous cell changes, a different problem from low-risk wart types. Under USPSTF guidance (2018, Grade A), screening runs from ages 21–29 with cytology every three years, and ages 30–65 with cytology every three years, high-risk HPV testing alone every five years, or co-testing every five years USPSTF. Newer guidance starts at 25 with a primary HPV test every five years as the preferred approach ACS. If you're due for a Pap during pregnancy, it can usually be done safely; abnormal results are typically followed up after delivery unless something needs immediate attention.
If you think you were recently exposed to an STI, warts can take weeks to months to appear, so a normal exam soon after contact doesn't rule them out. Here's when to test after exposure. To screen for other infections during pregnancy, you can also get tested.
Safe treatment in pregnancy
Many warts in pregnancy are left alone, especially if they're small and not bothersome, because they often shrink after delivery. When treatment is warranted, for comfort, bleeding, or warts that are spreading, a provider does it in the office, not with the usual home creams.
The patient-applied options used outside pregnancy are not recommended while pregnant. That includes imiquimod 3.75% or 5% cream, podofilox 0.5% solution or gel, and sinecatechins 15% ointment. Podofilox in particular is avoided because of potential toxicity CDC STI Tx Guidelines. Don't apply any leftover wart medication during pregnancy without checking first.
Provider-administered removal is the route during pregnancy. Expect several short visits rather than a one-and-done fix:
- Cryotherapy freezes warts with liquid nitrogen or a cryoprobe. It's quick, done in the office, and often repeated over a few visits as warts blister and fall off.
- Trichloroacetic acid (TCA) or bichloroacetic acid (BCA) at 80%–90% is a chemical applied directly to each wart by the clinician, also repeated on a schedule.
- Surgical removal, whether excision, curettage, laser, or electrosurgery, is used for large or stubborn warts that don't respond to freezing or acid.
No method is clearly best, and none cures the virus. Warts can come back after they're cleared because treatment removes the growth while the HPV stays. For a fuller breakdown of options outside pregnancy, see genital warts treatment.
A note on the HPV vaccine: it's not given during pregnancy and it prevents future infection rather than treating current warts. Gardasil 9, the only HPV vaccine distributed in the US since 2016, protects against future infection but won't clear warts or an infection you already have, and vaccinated people still need cervical screening ACS. If you're considering it later, here's how gardasil vs gardasil 9 compare.
Reducing transmission at delivery
There's no proven way to fully prevent passing HPV to a baby at birth, and routine cesarean is not recommended for that purpose. The most useful steps are practical:
- Tell your obstetric team about a wart diagnosis so they can examine you near term and plan accordingly.
- Reserve cesarean for obstetric reasons, for example warts so large they obstruct the birth canal or are likely to bleed heavily.
- Skip unproven home remedies and any prescription wart cream in late pregnancy; have removal done in the office if it's needed before delivery.
Because the warts often shrink after the baby arrives, many clinicians take a watchful approach and reassess postpartum rather than aggressively treating in the third trimester.
When to see a clinician
Bring up any new genital bumps with your prenatal provider, and don't try to diagnose or treat them yourself in pregnancy. Reach out sooner if warts are growing quickly, bleeding, painful, or numerous, or if they're large enough that you're worried about delivery. A clinician can confirm what they are, rule out look-alikes, and decide whether to treat now or wait.
After the baby is born, follow up so your warts can be reassessed and your cervical screening stays on schedule, and so you can talk through HPV vaccination if you haven't completed the series.
