Anatomical position as a predictor of hormonal therapy failure in palpable undescended testes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHormonal therapy for cryptorchidism shows limited long-term efficacy and is not routinely recommended by current guidelines, yet it continues to be used in practice. Evidence identifying anatomical subgroups with predictably poor outcomes remains limited. This study evaluated whether anatomical position predicts failure of hormonal therapy in palpable undescended testes.
methodsThis single-center retrospective cohort study included boys ≤ 14 years who received human chorionic gonadotropin (hCG) therapy for palpable undescended testes between 2015 and 2024. Testes were classified as high inguinal, low inguinal, external ring, or scrotal neck. The primary outcome was permanent testicular descent, defined as stable scrotal position for ≥ 6 months without re-ascent or orchidopexy. Multivariable logistic regression identified predictors of permanent descent.
resultsA total of 170 testes in 154 boys were analyzed. Overall permanent descent was achieved in 21.8%, with re-ascent occurring in 39.3% of initial responders, underscoring the importance of assessing durable rather than immediate outcomes. Success varied significantly by anatomical position (p < 0.001): external ring 50.0%, scrotal neck 38.1%, low inguinal 16.7%, and high inguinal 3.6%. Testes above the external ring accounted for 77% of treatment failures; additionally, 78.2% of testes ultimately required orchidopexy. Anatomical position was the strongest predictor of permanent descent, with markedly reduced odds for low inguinal (adjusted OR 0.19) and high inguinal (adjusted OR 0.04) positions compared with external ring.
conclusionsHormonal therapy failure in palpable undescended testes is highly predictable based on anatomical position. High and low inguinal testes demonstrate negligible to poor durable benefit, and orchidopexy should generally be preferred over hormonal therapy trials in these positions, though shared decision-making with families remains appropriate. External ring and scrotal neck testes represent the only subgroups in which selective hormonal therapy may be considered through shared decision-making with families. These findings refine guideline-based management by identifying where hormonal therapy should generally be avoided to prevent futile treatment.
