Can pubic lice cause infertility?

No. Pubic lice do not affect the reproductive organs or cause infertility.

Can pubic lice enter the vagina?

No. Pubic lice live on coarse hair and the skin surface. They do not enter the vagina or other reproductive organs.

Should my partner be treated?

Yes. Current sexual partner(s) should be treated at the same time to reduce the risk of reinfestation.

Can Pubic Lice Affect Your Reproductive Health?

Pubic lice are small parasitic organisms that infest coarse body hair. They most commonly affect your pubic region. They feed on the small amount of blood sucked from the underlying skin of the infested area to grow and multiply. This condition may result in intense itching, irritation, and discomfort.

Their mode of transmission is close physical contact, including sexual contact. However, pubic lice remain on the surface of the skin and hair and do not affect your reproductive organs. But accurate diagnosis and treatment are still important to prevent complications and reduce the risk of spreading the infestation.

What Are Pubic Lice?

Pubic lice (Pthirus pubis), sometimes called crabs, are tiny wingless parasites that live in coarse body hair.

They most commonly affect:

Pubic hair
Hair around the anus
Underarm hair
Chest hair
Beard or moustache
Eyebrows or eyelashes (less common)

Unlike head lice, pubic lice are adapted to grip coarse hair. Generally, they don’t survive for long away from the human body.

How Do Pubic Lice Spread?

Generally, pubic lice spread through close physical contact.

The following are the common modes of transmission:

Sexual contact
Skin-to-skin contact with an infested person
Sharing contaminated bedding, towels, or clothing (less common)

You cannot usually get pubic lice from the following:

Toilet seats
Swimming pools
Casual hugging
Sharing utensils

Can Pubic Lice Affect Your Reproductive Health?

Pubic lice do not directly affect your reproductive organs or fertility. These parasites inhabit only your skin and coarse hair. They do not invade the reproductive organs, such as:

Vagina
Cervix
Uterus
Fallopian tubes
Ovaries
Penis (in men)
Testes (in men)

As per current evidence, pubic lice:

Do not damage eggs or sperm
Do not interfere with ovulation
Do not affect sperm production
Do not cause infertility
Do not increase the risk of miscarriage

However, untreated pubic lice can still affect your overall sexual and reproductive well-being.

Persistent scratching may cause:

Skin irritation
Small sores or abrasions
Secondary bacterial skin infections
Pain or discomfort during sexual activity

Although these complications do not directly affect fertility, they may require medical treatment.

Why Are Pubic Lice Associated with Reproductive Health?

The presence of pubic lice may be associated with your reproductive health. This is not because pubic lice may damage your reproductive system, but because they are commonly transmitted through sexual contact.

So, if you are diagnosed with pubic lice, your doctor may recommend screening tests for certain sexually transmitted infections (STIs), including:

Chlamydia
Gonorrhoea
Syphilis
HIV

Because pubic lice are commonly spread through sexual contact, your doctor may recommend STI screening. Some untreated STIs can affect fertility if left untreated.

Therefore, diagnosing and treating these infections early helps protect your long-term reproductive health.

Although pubic lice may cause some discomfort, they have no direct effect on your fertility or reproductive health. They stay on the surface of the skin and hair and do not penetrate your reproductive organs.

Since pubic lice are often contracted through sexual contact, your doctor may suggest testing for STIs to determine if a person is infected with any diseases that may harm your reproductive health.
