Pubic hair acts as a protective buffer, reducing friction during intercourse and other activities. It can also prevent the transmission of bacteria and other pathogens.
Does it really have a purpose?
Yes, pubic hair has a purpose. First of all, it reduces friction during intercourse and prevents the transmission of bacteria and other pathogens.

There may be other reasons for our pubic hair.

Everyone has pubic hair, but we all make different decisions about what to do with it.

Some people prefer to grow it, while others prefer to cut, scrape or wax it. What you do with yours is up to you.

Read more about why it grows, how it affects hygiene, the risks associated with removal, and more.

What does it do?
When it comes to hair, humans are an anomaly among mammals.

However, this does not mean that pubic hair serves no purpose. We evolved this way for a reason.

Reduce friction
The skin around your genital area is thin. Pubic hair acts as a protective buffer and reduces friction during sex and other activities.

Some sources refer to pubic hair as “dry lubricant”. Because rubbing hair to hair is easier than rubbing skin to skin.

Pubic hair can also warm the genitals, which is an important factor in sexual desire.

Protection against bacteria and other pathogens
Pubic hairs act similar to eyelashes or nose hairs. It captures dirt, debris, and harmful microorganisms.

In addition, hair follicles produce sebum, which prevents the growth of bacteria.

This suggests that pubic hair may protect against certain infections, including:

sexually transmitted diseases (STDs)
urinary tract infections (UTIs)
yeast infection
Are there other benefits?
We don’t fully understand all the underlying causes of hair loss. Some additional theories are described below.

Indicates reproductive ability
Pubic hair appears during puberty. It is an obvious physical sign of sexual maturity and therefore reproductive capacity.

In the past, it may have served as a visual cue for potential mates.

Pheromone transmission
Another theory links pubic hair to the transmission of pheromones, or scented chemical secretions, that affect mood and behavior. We still don’t know how pheromones affect sex.

Pheromones are secreted by apocrine sweat glands. Compared to other parts of the body, there are more of these glands in the pubic area.

So, the theory goes, pubic hair traps pheromones and increases our attractiveness to sexual partners.

Is there such a thing as “too much” hair growth?
Pubic hair growth, including its location and thickness, varies from person to person. Some people have more pubic hair, some less.

Dramatic changes in hair growth sometimes indicate hormonal disorders.

For example, in an adult woman, excessive hair during childbirth can be a sign of polycystic ovary syndrome (PCOS).

This condition is caused by higher than normal levels of testosterone, the sex hormone that controls hair growth.

Other symptoms include irregular periods and hair growth on other parts of the body, including the face.

On the other hand, among those assigned male at birth, lack of pubic hair indicates low testosterone production.

Other symptoms of low T include decreased libido and erectile dysfunction.

If you experience irregular hair growth along with other unusual symptoms, see your doctor. Hormone therapy can help.

This is one of the most common misconceptions about pubic hair.

In a 2013 nationally representative survey of 7,580 people, 59 percent of women and 61 percent of men said they were hygienic when it came to taking care of their pubic hair.

But pubic hair is not hygienic.

Like any other hair on your body, your skin harbors sweat, oil, and bacteria. Therefore, they may smell a little stronger than other parts of your body.

If you wash regularly, this is not a cause for concern.

Why do people remove it?
There are many reasons why people choose to remove pubic hair. Some of the most common are discussed below.

Social norms
Hair care has been popular for centuries. Today, at least, hair removal is popular.

Some theories attribute this trend to the availability of porn, where hairlessness has become the norm.

Many people remove their pubic hair to meet this aesthetic standard.

For example, in the aforementioned 2013 study, 31.5 percent of women who reported taking care of their hair in utero did so.
