Underwear is commonly essentially the most ignored article of clothes, and many people could by no means give a second thought to precisely what we put on down there.
Nevertheless, specialists agree that the underwear you select can have optimistic or damaging results on the wellness of your genital space. As an illustration, underwear that makes you sweat extra can result in itching and yeast infections. Sure cuts of underwear, resembling thongs, can improve the chance of bacterial vaginosis or different infections. Underwear that’s too tight may cause constriction, chafing and bacterial infections, and there may be some proof that it may have an effect on fertility in males.
When choosing a pair of underwear, it’s vital to think about the material, match and reduce. And also you’ll need to take into consideration when and the way usually you modify or go with out underwear.
We spoke with 4 specialists — two OB-GYNs and two urologists — who gave us their finest recommendation for selecting and sporting underwear.
Stick to cotton or different pure materials.
When choosing a pair of underwear, the material is a serious consideration. “Usually talking, the most effective materials for underwear are pure materials like cotton,” mentioned Dr. Andrea Braden, a board-certified OB-GYN in Atlanta. “It actually has to do with the breathability of that material. We do know that air circulates higher with cotton underwear versus polyester. It is vital for vulvar well being to have good air circulation.”
Different good pure choices embody hemp, bamboo and linen, mentioned Dr. Suzy Lipinski, a board-certified OB-GYN at Pediatrix Medical Group in Denver.
Urologists agree. Dr. Scott D. Miller, the medical director at Wellstar Urology in Atlanta, mentioned that cotton stands out as a result of “it’s snug, cool, breathable, moisture-wicking and absorbent.” Nevertheless, “these traits are depending on the standard of the cotton fiber and numerous forms of weaves,” he famous.
And there are cases the place different materials may do higher. “Throughout instances of elevated perspiration, cotton can retain an excessive amount of moisture, resulting in bacterial and fungal overgrowth,” Miller added. “In these circumstances, a more sensible choice could also be a material fabricated from a mixture of cotton and an artificial fiber.”
Keep away from materials that don’t allow you to breathe down there.
Lipinski suggested towards “non-breathable materials,” together with synthetics resembling nylon and satin. Moreover, “woven, moderately than knit, materials or thick material may restrict how a lot [the fabric] breathes,” she mentioned.
Miller mentioned pure polyester “might be the worst material for underwear” and defined why.
“Though it’s among the many lightest supplies, it’s neither absorbent nor very breathable,” he mentioned. “Nevertheless, its sturdiness makes it a very good addition as a small proportion of [fabric blends].”
Should you’re uncertain of a selected material mix, Braden recommended that feeling the material will help you resolve. “It must be tender and never slippery.”
Even underwear that isn’t fabricated from a pure, breathable material will usually “have a cotton panel within the crotch space or gusset,” she added. And that’s a very good factor: “That’s as a result of cotton is essentially the most best material to be sitting in your ‘nether areas.’”
Choose a reduce that feels snug to you.
The medical doctors usually agreed that in relation to choosing a reduce of underwear, there’s no actual proper or unsuitable. Relatively, it’s about what feels snug to you and what permits your physique to breathe.
“The secret’s a snug match that’s not constricting or chafing,” Lipinski mentioned. “This implies totally different underwear for various physique varieties. … Ask your self, does the underwear really feel snug and transfer with you or tighten up and constrict? Does the underwear journey up or trigger chafing? Even two pairs of underwear in the identical reduce however [from] totally different manufacturers can match in a different way.”
Dr. Fenwa Milhouse, a board-certified urologist with Down There Urology in Chicago, mentioned that “loose-fitting underwear has lengthy been advisable,” including that “tight-fitting underwear reduces air circulation and should improve native moisture down there, which may trigger pores and skin irritation and cutaneous or pores and skin yeast infections.” Subsequently, she encourages her sufferers to select cuts which can be “most snug for them.”
Nevertheless, there could also be purpose to consider that sure underwear types are higher for fertility than others. Milhouse famous that a 2018 Harvard study evaluating semen parameters from nearly 700 males discovered that contributors who primarily wore boxers had a 25% increased sperm focus than those that didn’t.
Nonetheless, “briefs have the benefit of higher assist and safety,” Miller mentioned. “Boxers have the benefit of freedom of motion, though the additional materials could trigger bunching. Boxer-briefs mix the options of each, though most of those designs are form-fitting within the fashion of briefs.”

Take into account how usually you put on thongs.
Breathability doesn’t essentially imply much less material, with Lipinski noting how thong underwear tends to be tighter and extra constrictive.
“This doesn’t imply which you can’t ever put on it, simply possibly reduce use or save for these particular events,” she mentioned.
Additionally, contemplate your medical historical past.
“In case you are liable to infections, then you might need to keep away from sporting a kind of underwear that could be a thong or sits very carefully to the rear finish,” Braden mentioned, including that it may improve danger for bacterial vaginosis. “The explanation behind that’s which you can have micro organism tracked from the rectal space ahead when the material is mendacity that near the rectum. So in case you’re going via an an infection or liable to an infection, it’s most likely finest to put on one thing like a bikini or temporary, and even boy shorts.”
Change your underwear every day, at minimal.
The agreed-upon rule among the many medical doctors interviewed is to vary your underwear at the very least as soon as per day to verify issues stay clear and dry and to lower the micro organism load.
“Micro organism is regular. All of us have regular micro organism that lives on the vulva or within the rectal space,” Braden mentioned. “What you don’t need is progress of micro organism coming out of your clothes or your underwear.”
Braden defined how sporting underwear for lengthy intervals of time may cause infections or odors as a result of moisture mixes with the traditional micro organism that’s down there.
So it’s vital to vary your underwear as regularly as you’ll be able to. Some individuals could even need to contemplate altering their underwear greater than as soon as a day.
“In case you are energetic and sweat so much or wrestle with incontinence, then you might need to change much more regularly,” Lipinski mentioned.
Take into account going commando whenever you sleep.
Though some medical doctors discovered no subject with sleeping in underwear when completed correctly, others felt it could be helpful to go with out.
“Normally, I like to recommend sleeping with out underwear,” Milhouse mentioned, including that it permits your personal elements to get air air flow, decreases moisture and reduces irritation to the pores and skin.
“Even for my incontinent sufferers, at night time I encourage them to sleep with out underwear and pads and as an alternative sleep commando on an absorbent towel or sheet,” she mentioned.
Finally, the choice is extra about private desire. Nevertheless, it’s vital to concentrate to how your physique reacts.
“Should you’re having any complaints, resembling itchiness points, usually, the extra air the higher,” Braden mentioned. “The much less trapped the whole lot is towards your pores and skin, the higher the pores and skin is, the more healthy it’s. Sure, you’ll be able to sleep in your underwear, however make certain it’s one thing breathable, and be sure to are altering that every day.”
