Causes of itching around male private parts

Sweat, friction, tight clothing, fragranced products and recently changed detergent can irritate sensitive skin; [Contact Dermatitis](/conditions/contact-dermatitis/) is one possible pattern. Redness in moist folds can occur with [Skin Yeast Infection](/conditions/cutaneous-candidiasis/) or another rash. Dry, cracked skin may fit [Asteatotic Eczema](/conditions/asteatotic-eczema/), while a personal history of eczema may point toward [Atopic Dermatitis](/conditions/atopic-dermatitis/). Scaly plaques, flat purple or shiny areas and intense night itching have different possible causes, including [Psoriasis](/conditions/psoriasis/), [Lichen Planus](/conditions/lichen-planus/) or [Scabies](/conditions/scabies/).

Wash gently with lukewarm water, pat dry and change out of damp underwear promptly. Avoid scratching, deodorants and unprescribed steroid or antifungal mixtures because they may mask the appearance or irritate the area. A clinician may inspect the skin and ask about sexual contact, household itching, new products and discharge before recommending treatment. Avoid sharing towels until the cause is clearer.

Book an appointment if itching persists, returns, spreads or affects the penis or scrotum. Seek urgent care for severe swelling, intense pain, fever, rapidly spreading redness, blisters, ulcers, pus or difficulty passing urine. New genital symptoms after sexual contact deserve confidential assessment.

Does the rash look infectious, irritant or inflammatory? Should sexual or household contacts be assessed? Which products should I stop, and how should I protect the skin while it heals?
