Introduction
The testicl*s (plural testis) are the male reproductive organs inside the scrotum and produce and secrete sem*n and male reproductive hormones. The discoloration or darker pigmentation of the testis can happen gradually with age or may have several reasons. Some causes of darker discoloration of testicl*s are angiokeratoma of Fordyce, testicular torsion, and many more. This article explains some of the causes of testicular darkness and their causes and treatment.
What Conditions Can Lead to Dark Discoloration of testicl*s?
1. Tinea Cruris (Jock Itch)
It is a fungal infection that causes a red patch in the gonads or inner portion of the thighs, which is itchy. The shape of the rash is usually like a ring. The name Jock itch is given because the condition is common in athletes.
Causes: The infection is caused by person-to-person transmission of the fungus. It can happen by physical contact or by sharing contaminated towels or clothes.
Symptoms of Jock Itch: The infection begins with a red-colored rash on the skin, which gradually spreads to the upper thigh in the shape of a half-moon. The rash is either ring-shaped or in a bordered line of small blisters. It may be itchy, making the skin flaky or scaly.
Treatment: The treatment of Jock itch includes the administration of over-the-counter medicines known as an antifungal ointment, lotion, powder, or spray.
Prevention: Preventing fungal infection includes keeping the area of infection dry, washing the area with a clean cloth, and avoiding sharing personal towels and clothes.
2. Angiokeratoma of Fordyce:
It is a condition in which the spots are made up of blood vessels that expand, dilate, and become visible on the skin's surface.
Causes: Fordyce's exact cause of angiokeratoma is unknown, but some researchers suggest that high blood pressure can cause the appearance of spots. These spots are also seen in people suffering from hemorrhoids, chronic constipation, and irritable bowel syndrome. However, Fabry disease is one of the only proposed causes of angiokeratoma of Fordyce. It is of two types:
Type 1 (Classic): In this type of Fabry disease, the fat builds up quickly from birth. The symptoms start appearing during the teenage years or childhood.
Type 2 (Later-Onset): In this case of disease, the fat accumulates slower than type 1, and the signs and symptoms are only available once the person is in their 30s or even late 70s.
Symptoms: Along with dark black spots on the scrotum, some other symptoms caused by the condition are bowel symptoms, including diarrhea or constipation, hypohidrosis (insufficient sweating), ringing sounds in the ears, and visible eye cloudiness.
Treatment: Although angiokeratoma does not need treatment, the doctor may recommend its removal if the spots cause irritation or bother. The spots can be removed by procedures such as electrodesiccation and curettage (ED&C), laser removal, or cryotherapy (tissue freezing by the doctor).
3. Testicular Torsion:
Testicular torsion is a condition that occurs when the testicl*s rotate, and the spermatic cord is twisted, which brings blood to the scrotum. The reduced blood flow leads to sudden and often severe pain and swelling in the testicl*s. The condition also leads to the darkening of the testicular skin. It generally happens between the ages of 12 to 18 years. Sometimes, it can also occur before the birth.
Symptoms: The testicular torsion shows symptoms such as swelling of the scrotum, darker pigmentation of the skin of the scrotum, nausea and vomiting in some cases, and frequent urination.
Risk Factors: The chances of testicular torsion arise between the ages of 12 and 18 or in cases with a family history of testicular torsion. It can also reoccur if there is already an episode of testicular torsion.
Treatment: The torsion is generally corrected by surgery; however, in some cases, the doctor may untwist the testicl*s by pushing the scrotum back. This technique is known as manual detorsion. In cases of surgery, a small incision is made in the scrotum under general anesthesia, and the spermatic cord is untwisted. If necessary, one or both the testicl*s are stitched along with the scrotum. It is indicated to untwist the torsion as early as possible as it may be difficult to twist later and may reoccur.
4. Genital Warts: These are some of the most common sexually transmitted infections affecting the testicl*s or inner thigh areas. Warts can appear as both white or darker bumps resembling cauliflower.
5. Scrotal Dermatitis: It is an inflammation of the skin of the scrotum. Exposure to allergies and irritants regularly can cause this infection. This condition is characterized by severe itching, scaling, and erythema of the skin covering the scrotum. Many factors causing scrotal dermatitis are stress and contact dermatitis.
6. Physical Bruises: Any injury or trauma to the testicl*s can also lead to the darkening of the testicl*s due to the pooling of the blood in the tissues.
7. Ingrown Dark Hair Follicles: Often, removing hairs from the testicl*s by shaving or waxing leads to the growth of new hairs that are darker in color and make the testicl*s appear darker.
8. Pimples and Blackheads: These small skin conditions can be caused due to mild infections or clogging of the pores. Most of these pimples and blackheads are harmless and can be removed by simple home remedies and good hygiene.
9. Hyperpigmentation: The development of more pigments in some areas of the skin of testicl*s leads to a darker appearance. This can appear as lesions like freckles, moles, sun, or age spots.
10. HIV (Human Immuno-Suppressant Virus) Infection: This is a rare cause of darker testicl*s in a few cases.
11. Scrotal Eczema: This is a non-life-threatening condition. It is a dry and itchy skin problem. This condition usually affects the scrotum and the skin that covers the testicl*s.
How to Treat Dark testicl*s?
Treating the darker pigmentation or spots of the testicl*s depends on the underlying cause. Curing the cause may help to regain the normal skin of the testicl*s; however, in some cases, it may be irreversible.
Conclusion:
The darkening of testicl*s can be due to several causes, such as pooling of blood, inflammation, skin infections, fungal infections, and some diseases that may lead to dark spots. The symptoms and treatment of the cause of darkening depend on the underlying disease of the condition.
