Pubic hair, a distinctive feature of human anatomy, has been a subject of curiosity, cultural significance, and evolving grooming practices. This article explores various aspects of male pubic hair, including its biological functions, evolutionary origins, grooming trends, and potential health implications, drawing upon scientific research and expert opinions.
Pubic hair serves several important functions. It acts as a protective buffer for the sensitive skin in the genital region, reducing friction during sexual intercourse and other activities. Some sources describe it as a "dry lubricant," because hair-on-hair contact is less abrasive than skin-on-skin contact. Katy Burris, a dermatologist at ColumbiaDoctors, explains that pubic hair may reduce the likelihood of skin abrasion and injury during sexual activity.
Similar to eyelashes and nose hair, pubic hair traps dirt, debris, and potentially harmful microorganisms, protecting against infections such as cellulitis, sexually transmitted infections (STIs), urinary tract infections (UTIs), vaginitis, and yeast infections.
Pubic hair appears during puberty, signaling sexual maturity and reproductive ability. It may have served as a visual cue for potential mates in the past. Furthermore, pubic hair may play a role in pheromone transmission, as the pubic region has a high concentration of apocrine sweat glands, which secrete pheromones. Pubic hair may trap these pheromones, potentially increasing attractiveness to potential partners.
Humans are unique among primates in having a thick bush of wiry hair around their genitals. Robin Weiss, a researcher from University College London, suggests that this evolved as a visual signal of sexual maturation, standing out against the backdrop of an otherwise hairless body.

Intriguingly, human pubic hair shares similarities in texture with gorilla hair. Robin Weiss proposed that humans acquired pubic lice ("crabs") from gorillas. According to Weiss, the coarse, thick texture of human pubic hair is evolutionarily similar to that of gorillas, and crabs may have found their way to humans who ate gorillas and came into regular contact with gorilla carcasses, which made it possible for crabs to make the leap and feel right at home on humans' gorilla-esque pubes.
Grooming pubic hair has become increasingly common. A recent study found that more than 80 percent of women and about 50 percent of men groom their pubic hair regularly.
The primary motivations for pubic hair removal relate to concerns about appearance, hygiene, and sexual activity.
People have been removing hair from their bodies for centuries. Ancient Egyptians considered having pubic hair indecent and invented sugaring and waxing. In ancient Rome, a hairless pubis was a status symbol. Pubic hair trimming was not in fashion in Europe until the late 1900s. In America, the first waxing salon opened in 1987, and the technique gained popularity as Brazilian waxing.
Pubic hair removal carries potential risks. Injuries, such as cuts, burns, and rashes, are common. A study reported that 25.6 percent of groomers sustained injuries during or after hair removal. In rare cases, these injuries may require medical attention.

Removing pubic hair may increase susceptibility to infections, including UTIs, vaginitis, yeast infections, and skin infections like cellulitis and folliculitis. Grooming-related injuries, such as cuts, can also become infected.
Some studies suggest a link between pubic hair grooming and an increased risk of STIs. One study found that people who groom their pubic hair were more likely to report having had an STI at some point in their lives. However, more research is needed to determine if grooming directly contributes to this increased risk.
A nick in the genitals could lead to a life-threatening, tissue-destroying infection called Fournier’s gangrene. It only affects 1 in 7,500 people, but is more common in older men and can destroy the scrotum.
To minimize the risk of injuries and infections, it is essential to follow safe grooming practices:
Pubic hair does not hinder hygiene as long as the area is washed regularly with warm, soapy water. Avoid using scented products, as they can disrupt the pH balance and cause irritation.

Pubic hair color stands alone and doesn’t depend on the color of the hair on your head. The color is determined by the amount of melanin (a pigment substance) in each hair, which can be different because the amount of melanin is different in different parts of your body. In most cases, the color of your pubic hair is closest to the natural color of your eyebrows.
Most pubic hairs grow between half an inch and 1.5 inches, according to Steixner.
As you age and your testosterone decreases, usually in your 50s, you’ll start to notice things are a little less bushy down there.
