Testicular Examination During Well-Child Visits
Primary care providers should palpate testes for quality and position at each recommended well-child visit to detect undescended testes (UDT) and other abnormalities that may impact morbidity and mortality. 1
Importance of Testicular Examination
- Testicular examination is essential for detecting undescended testes (UDT), which occurs in 1-3% of full-term male infants and 15-30% of premature male infants 1
- Regular examination allows for detection of both congenital and acquired UDT, which can lead to reduced fertility, increased risk of testicular cancer, and potential testicular torsion if left untreated 1
- Approximately 70% of UDTs are palpable, while the remaining 30% may be located in the inguinal-scrotal area (30%), intra-abdominal (55%), or absent/vanishing (15%) 1
Timing and Frequency of Examination
- Testicular position should be assessed at every scheduled well-child visit throughout childhood due to potential changes in testicular position 1
- Special attention should be given to examination at the following ages:
Clinical Implications and Referral Guidelines
- Infants with UDT detected at birth who do not have spontaneous testicular descent by six months (corrected for gestational age) should be referred to an appropriate surgical specialist 1
- Boys with newly diagnosed (acquired) cryptorchidism after six months should also be promptly referred to a surgical specialist 1
- Phenotypic male newborns with bilateral nonpalpable testes require immediate specialist consultation to evaluate for possible disorders of sex development 1
- Boys with retractile testes should have their testicular position assessed at least annually to monitor for secondary ascent 1
Examination Technique and Documentation
- A thorough genital examination should include palpation of both testes for:
- Position (scrotal, inguinal, nonpalpable)
- Quality (size, consistency)
- Mobility (retractile versus fixed) 1
- Documentation of testicular examination findings is critical for detecting changes in testicular position over time 4
Common Pitfalls and Caveats
- Avoid unnecessary imaging studies (such as ultrasound) in the evaluation of UDT prior to specialist referral, as these rarely assist in decision-making 1
- Be aware that spontaneous descent of testes may occur in the first six months of life, but is unlikely after this period 1
- Remember that acquired UDT (testicular ascent) can occur later in childhood, with peak incidence around 8 years of age 1
- Children with cerebral palsy or neuromuscular disease are at higher risk for acquired UDT and associated testicular torsion, requiring vigilant examination throughout childhood 3
Regular testicular examination during well-child visits is a standard of care with Grade B evidence strength, supporting its importance in preventing morbidity and mortality associated with untreated testicular abnormalities 1.
