Name of the Condition

• Unilateral Inguinal Testis: Commonly referred to as an "undescended testicle" in one side (inguinal region).

Summary

• Unilateral Inguinal Testis is a condition where one testicle fails to move into the scrotum before birth, remaining in the groin area.

Causes

• The exact cause is not well understood, but potential factors include hormonal imbalances, anatomical issues, or genetic abnormalities during fetal development.

Risk Factors

• Premature birth
• Low birth weight
• Family history of undescended testes
• Maternal health issues during pregnancy, such as diabetes, or exposure to certain medications.

Symptoms

• Absence of one testicle in the scrotum
• Palpable mass in the groin area
• Asymmetrical appearance of the scrotum

Diagnosis

• Physical examination by a healthcare professional
• Ultrasound or MRI to locate the absent testicle if not palpable

Treatment Options

• Watchful waiting: Some cases self-resolve within a few months after birth.
• Hormonal therapy: Administration of hormones to encourage descending.
• Surgery (Orchiopexy): Recommended to lower the testicle into the scrotum, usually performed between 6 months to 2 years of age.

Prognosis and Follow-Up

• The outlook is generally positive if treated early.
• Regular follow-up is essential to ensure proper development and to monitor for potential complications.

Complications

• Reduced fertility due to impaired sperm production
• Increased risk of testicular cancer
• Hernia or twisting of the testicle

Lifestyle & Prevention

• No specific lifestyle changes to prevent the condition.
• Ensuring regular prenatal care and avoiding harmful substances during pregnancy may be beneficial.

When to Seek Professional Help

• If your child has a noticeable difference in the appearance of the scrotum or absence of the testicle at birth.

Tips for Medical Coders

• Ensure accurate documentation of the laterality (left or right) of the condition since it is a unilateral issue.
• Avoid confusion with bilateral conditions or related but different conditions like retractile testis.
