Itching in the private parts of a man can be caused by several reasons, including:

• Tinea cruris: Also known as jock itch, this is a type of fungal infection that causes redness and itching in the warm and moist areas of the body, such as the groins, buttocks, and inner thighs.

• Allergy to latex condoms: This can cause itching and irritation in the genital area.

• Uncontrolled diabetes: High blood sugar levels can lead to yeast infections, which can cause itching in the genital area.

• Pubic lice: These tiny insects can cause intense itching in the pubic area, leading to inflammation from scratching.

• Scabies: This is a contagious skin condition caused by tiny mites that burrow into the skin and cause intense itching.

• Eczema: This is a skin condition that can cause red, itchy, and inflamed skin in the genital area.

• Psoriasis: This is a chronic autoimmune condition that can cause red, scaly patches on the skin, including the genital area.

• Contact dermatitis: This is a type of skin inflammation that occurs when the skin comes into contact with an irritant or allergen, such as soap, laundry detergent, or fabric softener.

• Balanitis: This is a condition that causes inflammation of the foreskin and head of the penis, which can cause itching and discomfort.

• Sexually transmitted infections (STIs): Several STIs can cause itching in the genital area, including genital herpes, chlamydia, gonorrhea, and trichomoniasis.

To avoid itching in the genital area, men should keep the area clean and dry, avoid wearing tight undergarments, and avoid using scented products, such as soaps and lotions, in the genital area. If the itching persists or is severe, it is important to see a healthcare provider for diagnosis and treatment.
