It is common to experience a need to itch every now and then, but if you feel the need to scratch all the time it’s probably time to seek some help. Inadvertently, there would be a concern of any possible sexually transmitted diseases (STD), but not all itches are sexually transmitted. – STD Screening in Singapore
Listed below are some of the more common causes of itchy testicles.
Chafing is an irritation of the skin caused by repetitive friction. This is typically caused by inappropriately sized clothing and is commonly experienced by guys doing biking or running. It can happen anywhere on the skin but vulnerable areas are the groin, thighs, underarms and even the nipples. Chafing is easy to prevent though, by wearing the right clothes and using some form of barrier cream/ointment like vaseline to protect vulnerable areas.
- Jock Itch
Jock Itch, also known as tinea cruris, this is a fairly common condition seen in gentlemen who exercise a lot or are involved in jobs involving heavy physical activity. This creates a warm, moist environment on the scrotum that is ideal for fungal growth. Common symptoms are an itchy and red rash on the scrotum that can be scaly in nature. Treatment is through the use of oral or topical antifungal medications. Jock Itch can be prevented by regular change of clothing after heavy exertion as well as use of antiperspirants.
- Contact Dermatitis
Contact dermatitis is a type of eczema triggered by contact with a particular substance. The skin can become red and cracked with blistering and sometimes can resemble jock itch. Common causes of contact dermatitis are new soaps and detergents, so if the new soap/detergent is causing itchy testicles, it might be a good idea to swab back.
- Lichen Simplex Chronicus
This is what happens when you leave an itch too long without seeing a doctor. After prolonged itchy, rubbing and scratching of the skin, the scrotum can become lichenified. Like lichen on the trees, the skin can become thick and scaly with accentuated skin fold lines. This is an extremely pruritic chronic itch, and the treatment is usually the use of a strong steroid cream to thin out the lichenified skin.
Psoriasis is an unpleasant skin condition presenting as reddish rashes with silvery scaling over the whole body. It commonly involves the scrotum and it can be itchy as well. There are also other dermatological conditions which may look similar to psoriasis and can involve the scrotum as well. This is why it is important to see a doctor if there is an odd looking rash over the scrotum that does not go away on its own.
- Pubic Lice
Also known as crabs, Pthirus pubis is a very small insect that parasites humans. Pubic Lice are commonly found attached to the hair in the pubic region but can also be found in other coarse hair elsewhere on the body, for example eyebrows or armpits. Other than the adult insects, eggs known as “nits” can also be found attached to the hair. Pubic lice is normally spread through sexual contact. It is however very easily treatable by over the counter anti-louse preparations.
Sarcoptes scabiei are tiny eight legged mites that live within the human skin. Allergic reaction to the mites, eggs and faeces can lead to an intense itching that is worse at night. Symptoms are a pimple like rash over the scrotum that can be very itchy out of proportion to the rash. Scabies is spread through skin to skin contact and hence can be sexually transmitted. It’s treated with an anti-mite topical preparation known as permethrin.
The astute reader might realise that not a lot of STDs are found on the above list. The truth is that the majority of STDs do not lead to testicular itching but rather other symptoms like ulcers or discharge. If itchy testicles are still a problem, it is still better to seek a doctor for a medical consultation.
