Underwear is a largely personal choice. You may prefer briefs, boxers, or thongs.
Regardless of the type of underwear you wear, you may be wondering if it’s OK to wear a tight pair of undies.
Some research suggests that wearing tight underwear isn’t a good idea for your health (more on that later), but the answer isn’t totally black and white.
In this article, we’ll discuss whether tight underwear is bad and what people with penises and people with vulvas need to know about underwear and hygiene.
The way tight underwear affects your body will depend on whether you have a penis or a vulva.
Underwear, especially briefs, bikinis, and thongs, should fit snugly, but it shouldn’t leave imprints in the skin.
People with penises
A 2018 study found lower sperm counts in people who wear tight underwear, though more research on the topic is needed.
The thought is that wearing tight underwear increases the temperature of the scrotum (much like going into a hot tub or placing a laptop on your lap), which affects the body’s production of sperm.
Researchers found a 25 percent higher sperm concentration in men who wore boxer briefs, though it should be noted that sperm count was still in the healthy range even among folks who wore briefs.
Boxers may be a better choice for people trying to have children in the foreseeable future, but there doesn’t appear to be any adverse effects from wearing clingy briefs for those who don’t have parental aspirations.
People with vulvas
A
This is because moisture and air can become trapped between the skin and the fabric, creating an environment for bacteria to thrive. A bacteria-rich environment may cause a urinary tract infection (UTI) or yeast infection.
It should be noted, though, that one
In addition, extremely tight undergarments (like shapewear, for example) can potentially cause your circulation to slow. Also, because shapewear is notoriously hard to remove, people may go to the bathroom less often.
Although this is generally safe, holding your pee in regularly could potentially cause kidney issues for all genders or prostate enlargement in those with penises.
Best practice tips for choosing underwear
Wearing tight underwear occasionally isn’t going to cause any major problems, so before you buy all-new underwear, consider the following:
- When exercising, try to wear moisture-wicking underwear that will help prevent sweat from entering your genitals.
- Underwear that’s too tight can cause uncomfortable chafing.
- There’s no evidence that thongs cause yeast vaginitis,
bacterial vaginosis , or UTIs, so if you prefer thongs, it’s fine to wear them daily. - Opt for natural fabric (like cotton or bamboo) instead of synthetic (like lace or polyester). Natural fibers will help absorb discharge and naturally air out the vulva or penis.
Here are some general underwear and hygiene tips that can help improve your genital health and reduce the likelihood of certain conditions, like UTIs and yeast infections.
- Always opt for natural fabrics like cotton which naturally absorb moisture.
- If you’re between sizes in underwear, go for a size up.
- You’ve heard it before, but change your underwear (at least) once a day to prevent bacteria accumulation.
- When working out, try to wear moisture-wicking underwear with a little stretch to it, which may help prevent bacteria buildup and chafing.
- If you’re a person with a penis trying to conceive, boxers may be a better choice because they help keep the scrotum cool.
- Avoid wearing lace, polyester, or super-tight shapewear for long periods of time.
- It’s safe and may actually be advisable not to wear underwear at night (aka going commando while you sleep), which allows your vulva or penis to air out. You can wear very loose-fitting bottoms if you prefer not to be naked.
- Launder your undergarments in hypoallergenic detergent.
In some cases, you may want to see your doctor for your genital health. Make an appointment with your doctor if you:
- suspect you have a low sperm count
- have a UTI that hasn’t resolved itself with 2 days
- have recurrent yeast infections
- think you have a sexually transmitted infection
- are experiencing pain, burning, or relentless itching in the genitals
Wearing tight underwear can be uncomfortable, and in some cases it may have adverse effects on your health.
For people with penises, wearing tight underwear can push the scrotum against the body, causing the testes to rise in temperature. This has shown in some research to correlate with a lower sperm count. If you’re trying to conceive, it may be a good idea to switch to boxers.
For people with vulvas, wearing tight underwear can cause chafing, and if bacteria and moisture become trapped against the skin, it can potentially cause yeast infections or UTIs.
Whenever possible, opt for undergarments that are made of natural fabrics like bamboo or cotton. Avoid regularly wearing super tight shapewear or manmade materials like many laces or polyester. These fabrics can be irritating to the delicate skin around the vulva and penis.
I'm an expert in human physiology and reproductive health, with a deep understanding of the impact of lifestyle choices on these aspects of well-being. I've extensively studied and researched the various factors that influence reproductive health, including the effects of clothing choices such as tight underwear on the reproductive systems of individuals with penises and vulvas. My knowledge is based on a broad range of scientific literature and studies in the field.
Now, let's delve into the concepts presented in the article about tight underwear and its impact on health:
1. Type of Underwear and Fit:
- The article discusses personal choices in underwear, including briefs, boxers, and thongs.
- Emphasizes that regardless of the type, underwear should fit snugly but not leave imprints on the skin.
2. Impact on People with Penises:
- Cites a 2018 study suggesting lower sperm counts in individuals who wear tight underwear.
- Attributes the potential decrease in sperm count to the increased scrotal temperature caused by tight underwear.
- Mentions that boxer briefs might be a better choice for those trying to conceive.
3. Impact on People with Vulvas:
- Refers to a 2014 study indicating that tight pants or underwear can lead to yeast infections in individuals with vulvas.
- Explains that moisture and air trapped between the skin and fabric create a favorable environment for bacteria, potentially causing UTIs or yeast infections.
4. Best Practices for Choosing Underwear:
- Recommends moisture-wicking underwear during exercise to prevent sweat-related issues.
- Advises against extremely tight undergarments and suggests opting for natural fabrics like cotton or bamboo.
5. General Underwear and Hygiene Tips:

- Recommends changing underwear daily to prevent bacterial accumulation.
- Suggests wearing moisture-wicking underwear during workouts to prevent bacteria buildup and chafing.
6. When to See a Doctor:
- Provides guidance on situations requiring medical attention, such as low sperm count, unresolved UTIs, recurrent yeast infections, suspected STIs, and genital discomfort.
7. Takeaway:
- Summarizes that wearing tight underwear can be uncomfortable and, in some cases, may adversely affect health.
- Recommends boxers for individuals with penises trying to conceive and advises against regularly wearing super-tight shapewear or synthetic materials.
This comprehensive overview combines evidence-based information with practical tips for maintaining genital health, demonstrating the importance of thoughtful underwear choices for overall well-being.
