    Crotch sticking when wearing underwear may be related to factors such as inappropriate size of underwear, non-breathable material, unreasonable cutting design, etc. It may also be caused by scrotal eczema, tinea cruris and other diseases. It is recommended to choose loose and breathable cotton underwear to avoid friction from sitting for a long time, and to check for skin diseases in time.

    1. Underwear size is too small

    Underwear that is too tight in the waist or crotch area will directly compress the perineal area. Male testicles need an environment below body temperature. Tight underwear will cause local temperature to rise and affect sperm activity. It is recommended to measure the hip and thigh circumference and choose boxer briefs that are 5 cm larger than the actual size.

    2. Chemical fiber material stimulates

    Synthetic fibers such as polyester have poor hygroscopicity, and accumulation of sweat after exercise can easily breed bacteria. Chemical dyes may cause contact dermatitis, an itchy papule. Pure cotton or modal fabrics can reduce friction, and bamboo fiber materials also have natural antibacterial effects.

    3. Briefs design defects

    The Y-shaped seams of traditional briefs can easily dig into the groin, and the narrow crotch design will cause frequent friction between the scrotum and thighs. You can choose three-dimensional tailoring underwear with a seamless design. The crotch adopts a drop-shaped space structure to leave room for movement of the genitals.

    4. Scrotal eczema

    Fungal infection or allergic reaction can cause the scrotal skin to thicken and crack, causing a stinging sensation when underwear rubs against it. When accompanied by symptoms such as erythema and desquamation, you can use triamcinolone acetonide econazole cream or tacrolimus ointment as directed by your doctor to avoid scratching the affected area.

    5. The spread of tinea cruris

    When Trichophyton rubrum infects the groin area, the annular skin lesions will produce a burning sensation when irritated by sweat. It needs to be differentially diagnosed with eczema. After diagnosis, bifonazole cream combined with miconazole nitrate powder can be used externally. Close-fitting clothing needs to be scalded and disinfected with boiling water.

    The perineum should be kept clean and dry every day, and underwear should be changed in time after exercise. Newly purchased underwear must be washed first to remove formaldehyde residues, and avoid using softener during washing. If symptoms such as persistent itching and exudation occur, you need to see a dermatologist. Diabetic patients need to be more vigilant about fungal infections. It is recommended to replace a batch of underwear every six months. If the crotch becomes hard and yellow, it needs to be eliminated.
