And the report, published today, warned of one particularly dangerous technique which seems to be causing the most damage: lying on your back and having others groom your pubic hair.
Laceration was the most common injury, followed by burning and rashes. Shaving is by far the most common method.
It also found that the popular trend of removing all pubic hair, as they do in a Hollywood wax, drastically increases your risk of sexually-transmitted infections like HPV - something health experts have been warning for years.
Out of 7456 adults surveyed, 5674 said they had groomed their pubic hair at some point during their lifetime. About 4800 were married or living with a partner and about 1750 were single, divorced or separated.
The most common position for grooming was standing (75 per cent), followed by sitting (22 per cent), squatting (13 per cent), and lying down (12 per cent).
While most people (77 per cent) look directly at the area they are grooming, a fifth (21 per cent) used a mirror, while many (17 per cent) admitted they didn't look at all.
Shaving with a non electric razor was easily the most common method, used by 47.5 per cent of people.
A quarter of people (27 per cent) used an electric razor, many used scissors (18 per cent), while just 2.6 per cent waxed and just 0.6 per cent had laser hair removal.
The report found 133 groomers were treated for infections after manicuring their genital area.
Meanwhile, 49 received antibiotics for lacerations, and 36 had severe injuries that required surgical intervention.
Surgeries included draining abscesses and stitching up wounds.
For males, scrotum injuries were most common and penile injuries were also frequent. They rarely reported pubis injuries.
But the opposite was true for females, who had a high number of injuries to the pubis. Females also sustained injuries to the inner thigh and vagina.
Injuries to the perineum and anus were far less common than others for both males and females.
The 1.4 per cent of injuries that required medical attention were associated with people lying on their back and letting someone else groom them.
Not being able to see the grooming process makes it more dangerous, the study said.
But there are pros and cons to having a partner groom your pubic hair in this position.
"Having a partner perform one's grooming eliminates a self-tactile sensation, which may predispose to injury. Alternatively, a grooming partner may encourage the injured to seek medical attention," the study said.
Reflecting on the data, Dr Arash Akhavan from the Dermatology and Laser Group in New York told Daily Mail Online it is hardly surprising.
"In our office we see patients regularly with infections and rashes related to pubic hair grooming," he said.
He said using a clean or new razor is the most important safety tip if you are planning to groom yourself at home.
"Using a dirty razor puts you at risk for an infection of the hair follicles called folliculitis, often caused by Staph bacteria," Akhavan said.
He warned to see a physician or dermatologist if you have an infection, saying it can get out of hand.
Akhavan recommended using a shaving cream specifically for sensitive skin.
He said to shave in a single direction because shaving in multiple directions can lead to ingrown hairs.
And he said to make sure whoever you have wax your pubic hairs is a "well trained and experienced professional".
"The skin in this area is very delicate and sensitive and prone to injury from incorrect waxing technique," Akhavan said.
The American Medical Association study found that waxing is a more common method for women and it causes them less injuries.
Akhavan said choosing laser hair removal to groom pubic hairs prevents injuries and recommended the technique for those who can afford it.
The study said the fact that more younger people are grooming their pubic hair "could signify a generational trend, indicating that this behavior may continue to become more universal as the population ages".
The average age of the survey's participants was 41.9 years old and 68.1 per cent were white, 12.6 per cent were Hispanic and 12.3 per cent were black.
The respondents were from different geographic areas, were between 18 and 65 and had a wide range of sexual activity patterns, according to the study.
The study outlined the differences in the reasons men and women chose to groom their pubic hair, including sexual appeal, partner preference, oral sex and routine care and hygiene.
Sexual appeal is particularly a concern among women.
"Reasons for removing all pubic hair in women have been linked to feelings of sexual attractiveness and self-enhancement," the study said.
It also said the reasons men choose to remove pubic hair have not been investigated but have been linked to "increased sexual activity and improved self-perception of appearance".
PUBIC HAIR GROOMING 'DOS AND 'DON'TS
Do:
• Shave your pubic hair in one direction, as shaving in different directions can cause you to have an ingrown hair
• See a physician or dermatologist immediately if you think you have an infection
Don't:
• Never let someone who has not had experience waxing pubic hair groom you
• Do not use a razor that is old or dirty, as it increases your risk of infection
THE DANGERS OF PUBIC HAIR GROOMING: HOW IT CAN LEAD TO AN STD
A study from the University of California last year said that adults who trim their pubic hair are 80 per cent more likely to get an STD.
This risk is four times higher for those who get a Brazilian wax, which removes all pubic hair.
The more times someone grooms their pubic hair, the higher the risk of getting an STD becomes.
High frequency groomers - those who groom their pubic hair daily or weekly - are three-and-a-half times more at risk.
Study author Dr Benjamin Breyer said one reason for this is people who groom themselves might be more likely to participate in 'risky sexual behaviours' than those who do not.
WHAT IS FOLLICULITIS: A COMMON INFECTION CAUSED BY SHAVING
• Folliculitis occurs when a hair follicle gets inflamed so it can appear on any part of your body that grows hair
• It is most common on one's arm, leg, back, buttocks and beard area
• It can be caused by bacteria, fungus or yeast
• Shaving or wearing tight clothes that rub the skin can also cause the infection
• You can get folliculitis from swimming pools or hot tubs that have not been treated with chlorine properly
• Having a disease that makes it harder for your body to fight infection, such as diabetes or HIV, makes you more likely to get folliculitis
