Name of the Condition
- Absence and Aplasia of Testis (Q55.0)
- Also referred to as Testicular Aplasia, Congenital Absence of Testis
Summary
Absence and aplasia of the testis is a congenital condition where one or both testes are missing or never developed. This can occur due to developmental issues before birth, leading to absent testicular tissue.
Causes
- Genetic anomalies or chromosomal abnormalities can lead to the condition.
- Developmental disruptions during pregnancy that affect testicular formation.
- The exact cause is often unknown but may be linked to factors affecting embryonic development.
Risk Factors
- Family history of similar congenital anomalies.
- Maternal exposure to certain chemicals or drugs during pregnancy.
- Genetic syndromes that include testicular aplasia as a feature.
Symptoms
- Absence of one or both testes in the scrotum.
- Possible absence of secondary sexual characteristics if bilateral absence occurs and affects hormone production.
- Undescended testicle (cryptorchidism) during childhood.
Diagnosis
- Physical examination to detect missing testes.
- Imaging studies, such as ultrasound or MRI, to confirm the absence of testicular tissue.
- Genetic testing may be conducted to identify underlying syndromes.
Treatment Options
- Hormone Replacement Therapy: If hormone production is affected, testosterone replacement may be necessary.
- Prosthetic Testicles: Surgical placement of testicular prosthetics for cosmetic appearance.
- Counseling and Support: Psychological support for coping with the condition.
Prognosis and Follow-Up
- Prognosis depends on the presence of one or both testes and any associated hormonal issues.
- Regular monitoring and follow-up to assess hormonal levels and development, especially during puberty.
- Fertility may be impacted if both testes are absent.
Complications
- Potential infertility if both testes are absent.
- Psychological impact due to cosmetic or identity concerns.
- Possible endocrine disorders if hormonal imbalance occurs.
Lifestyle & Prevention
- While the condition itself cannot be prevented, early detection and management can improve quality of life.
- Educating parents on potential genetic risks if there's a family history.
When to Seek Professional Help
- Any detection of an absent testis during a routine physical examination.
- Concerns regarding delayed puberty or development.
- Psychological distress related to the condition.

Tips for Medical Coders
- Ensure accurate coding by confirming the diagnosis with available medical records.
- Be aware of dual coding when the absence is related to genetic conditions or syndromes.
- Avoid confusing testicular aplasia (congenital absence) with conditions like testicular atrophy or undescended testis.
