Scrotal Disorders and Functions

Exploring the Functions and Disorders of the Scrotum

The scrotum is the external part of the male reproductive system. It appears like a pouch that develops from the skin of the abdomen's anterior wall. This part of the body derives from the labioscrotal swelling during the fourth week of embryonic development.

This fibromuscular and cutaneous sac is located below the penis and contains reproductive organs, such as testes. The primary function of the scrotum is to protect the testicles through thermoregulation.

What are the functions of the scrotum?

The functions of the scrotum are listed below:

1. Protection of testicles: Scrotal tissues of the scrotum protect testicles, keeping them a few degrees below average body temperature. The cremaster muscle, a thin muscle in the scrotum wall, contracts in a cold environment to pull the testicle closer to the body and conserve heat.

When the temperature turns hot, the same muscle relaxes, allowing the testicles to move away and facilitate heat dissipation.

1. Sperm Production: The scrotum produces sperm by regulating the temperature of the testicles. When the temperature of the testicles is lower compared to the body's core temperature, it becomes more efficient during spermatogenesis (sperm production).

What are Common Scrotal Skin Issues?

The following are common scrotal skin issues:

1. Scrotal Eczema: Scrotal eczema, or scrotal dermatitis, appears on the scrotum and in the genital area and causes itching, redness, burning, leathery skin and swelling. The cause of scrotal eczema includes seborrhoeic dermatitis, which refers to an inflammatory response to Malassezia yeast in the groin area. Medical experts diagnose the condition when they see rashes. Treatments of scrotal eczema mainly focus on reducing the itching with the use of topical steroids and emollients.
2. Scrotal Cysts: Scrotal cysts are types of abnormal fluid sacs inside the scrotum. Besides the testes, the scrotum also contains the epididymis, which is a long tube connected to both testicles. Epididymis cysts contain sperm cells along with fluid. AAnother common type is an epidermoid cyst (often mistakenly called a sebaceous cyst), which is filled with a soft, keratinous material.

What are the symptoms of scrotal skin issues?

The symptoms of scrotal skin issues include:

1. Severe or mild pain in the area
2. Sores and rashes
3. Heavy feeling
    

What are Common Internal Scrotal Disorders?

The following are the causes of scrotal skin issues:

1. Hydrocele: Hydrocele occurs when the scrotum fills up with fluid, which causes swelling. It is a common condition that can affect babies as well as adults.
2. Spermatocele: Spermatocele develops behind the testicles when fluid-filled sacs start to grow on the epididymis. It is a benign condition and has few symptoms.
3. Epididymitis: An inflammation in the epididymis is called epididymitis. The epididymis is the tube at the back of the testicle that carries sperm.
4. Varicocele: Varicocele refers to enlarged veins in the scrotum causing discolouration in scrotal skin. The condition causes dull pain and generates a heaviness in the scrotum.
    

How are Scrotal Skin Disorders Diagnosed?

When fluid-filled sacs or bumps appear in the scrotum and cause discomfort, it is necessary to consult with a physician. Physicians might perform the following tests to diagnose scrotal disorders:

1. Blood tests to detect if there are any infections
2. Skin scrapings to check for bacterial or fungal infection
3. Imaging tests to check if the patient has any abnormalities
4. A swab of the urethra to evaluate whether there is any chance of sexually transmitted diseases
5. Urinalysis to assess the blood cells and chemicals in the urine
    

What are the treatment methods for scrotal skin disorders?

Treatments for scrotal disorders include:

1. Medications: Certain medications like corticosteroids, moisturisers, and oral steroids help to manage the symptoms of scrotal eczema.
2. Surgeries: When symptoms of the scrotal cysts persist, increasing discomfort for the patient, doctors recommend surgical removal. This includes making a small incision in the scrotum and removing the cyst.
3. Minimally Invasive Therapies: The sclerotherapy procedure is considered extremely effective in puncturing cysts and draining their contents. Sometimes this process also includes injecting cysts with an agent to promote their healing.
4. Lifestyle changes: Lifestyle changes like a healthy diet, stress management, wearing light-fitted clothing and avoiding triggers can support testicular health and mitigate scrotal disorders.

Is it Possible to Lead a Normal Life with Scrotal Skin Disorders?

Living a normal life with a scrotal disorder is possible if the symptoms are not severe. Although some conditions require immediate intervention by a medical professional. Identifying the triggers and practising good hygiene is crucial.

To ensure the scrotum’s good health, it is necessary to keep it dry and clean. Performing monthly self-checkups also helps in monitoring the area for swelling or tenderness. Finally, last but not least, using protection while involved in any kind of sexual activity will help to prevent sexually transmitted infections effectively.
