OBJECTIVES: Cryptorchidism is the most prevalent pediatric genital anomaly, yet its clinical significance often extends beyond simple anatomical maldescent. While surgical management is well-established, the necessity for holistic endocrine and genetic evaluation remains underexplored. We aimed to characterize the clinical, hormonal, and genetic landscapes of patients referred for pediatric endocrinological assessment following orchiopexy.
METHODS: We retrospectively analyzed 99 boys referred for postoperative evaluation. Clinical findings, basal and dynamic hormonal profiles, and genetic results - including karyotype and targeted DSD gene panels - were evaluated.
RESULTS: Preterm birth was recorded in 23.2 % of the cohort, and bilateral involvement was present in 50.5 %. Significant clinical findings included testicular atrophy (34.3 %), scrotal hypoplasia (18.2 %), micropenis (12.1 %), and hypospadias (10.1 %). Hormonal profiling revealed a broad spectrum of FSH (up to 85.7 mIU/mL) and AMH (0.01-71.80 ng/mL) levels. Among patients undergoing hCG stimulation testing, 72.7 % exhibited an insufficient testosterone response. Targeted DSD panel testing in a selected high-risk subgroup yielded a diagnostic rate of 45.4 %, identifying variants in SRD5A2, PTPN11, NR0B1, RAF1, POR, LHX4, and AMHR2. The prevalence of nonisolated cryptorchidism was relatively high, affecting 44.4 % of the cohort. This multisystemic involvement comprised defined syndromic diagnoses (17.2 %) and chronic comorbidities (27.3 %), predominantly endocrine disorders such as congenital hypothyroidism and growth hormone deficiency.
CONCLUSIONS: The high frequency of bilateral involvement, testicular atrophy, and genetic mutations suggests that many referred cases represent complex syndromic or endocrine conditions rather than isolated maldescent. Comprehensive endocrinological follow-up and targeted genetic testing are essential for early diagnosis and optimizing long-term fertility management.
