Does Herpes Affect Fertility? Real Talk on HSV, Pregnancy & Your Fertility Future

Let’s talk about something a lot of us wonder—but rarely ask out loud.

Maybe you’ve just been diagnosed with herpes (HSV-1 or HSV-2), or maybe you’ve known for a while and are now thinking about trying for a baby. Either way, you might be asking yourself: “Will this affect my fertility?”

First, take a deep breath. A herpes diagnosis doesn’t define your future—and it doesn’t close the door on fertility or parenthood. Let's break it down, clearly and kindly.

What Is Herpes?

Herpes Simplex Virus (HSV) comes in two types:

• HSV-1: Usually causes oral herpes (cold sores), but can also affect the genitals.

• HSV-2: Typically causes genital herpes.

It’s incredibly common—more than two-thirds of the global population under 50 have HSV-1, and around 11% have HSV-2. Many don’t even know they have it.

It spreads through skin-to-skin contact and can lie dormant for months or years before causing symptoms (if it ever does).

So, Does Herpes Affect Fertility?

Here’s the reassuring answer: In most cases, herpes does not directly impact fertility.

You can still ovulate, conceive, and carry a healthy pregnancy. But there are a few nuances to understand—especially if you're actively trying to conceive (TTC) or planning IVF.

How Herpes Might Interact with Fertility

1. During an Active Outbreak

If you or your partner have a visible outbreak, it’s best to avoid unprotected sex. That’s because the virus is most contagious when symptoms (like sores or tingling) are present. If you’re TTC naturally, this might disrupt timing—but it won’t harm your fertility.

2. Fertility Treatment (IVF, IUI, etc.)

Clinics often check for STIs, including HSV. Having herpes won't disqualify you from treatment, but doctors may delay a procedure if you’re mid-outbreak to avoid spreading infection during egg retrieval or embryo transfer.

Communication with your fertility clinic is key—being open helps them support you safely and confidently.

3. Male Fertility

Some studies have explored whether HSV can affect sperm quality—but the research is mixed, and any potential impact is usually mild. Most people with HSV can conceive without additional complications.

Pregnancy & Herpes: What to Know

While herpes usually doesn’t impact fertility, it can matter during pregnancy—especially close to delivery.

• If a pregnant person has a new herpes infection in the third trimester, there’s a higher risk of passing it to the baby during birth.

• If it’s a recurrent infection, the body has antibodies that help protect the baby. Doctors may recommend antiviral medication during the last month of pregnancy to reduce the risk of transmission.

Some people with active lesions during labor may be advised to have a C-section for safety.

But again—this doesn’t stop you from having a healthy pregnancy or baby. With the right care, outcomes are overwhelmingly positive.

Emotional Check-In

A herpes diagnosis can come with a heavy dose of shame, stigma, or fear—especially around fertility. But it’s more common than you think, and it doesn’t make you less worthy of love, health, or parenthood.

You’re not alone. And you have options.
