Effect of Pre-operative Parenteral Testosterone on Penile Dimensions and Vascularity in Proximal Hypospadias: A Prospective Observational Study.
Observational study in African journal of paediatric surgery : AJPS, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
introductionSevere or proximal hypospadias is associated with inadequate local tissue and small phallus size. Pre-operative androgens have been used to increase phallus size, but there are very few studies on its role in proximal hypospadias. This study aimed to assess the effects of pre-operative intramuscular (IM) testosterone on proximal penile hypospadias in terms of penile morphology and tissue characteristics of penile skin. MATERIALS AND
methodsThis prospective observational study was conducted on 27 patients of proximal hypospadias over a period from June 2017 to July 2018. The patients were sequentially enrolled into two groups: Group A and Group B. Group A patients received IM testosterone before surgery, whereas Group B patients were operated without pre-operative testosterone. Outcomes were analysed in terms of change in penile dimensions and effect on vascularity of penile skin.
resultsPre-operative IM testosterone in Group A caused a significant increase in stretched penile length from a mean of 3.058 cm (±0.691) to 3.9 cm (±0.875) ( P = 0.002), penile circumference from a mean of 4.142 cm (±0.772) to 4.667 cm (±1.174) ( P = 0.029) and glans width from a mean of 1.225 cm (±0.245) to 1.750 cm (±0.571) ( P = 0.002). There was higher microvessel density in the preputial skin of Group A (mean: 12.212 [±4.745] blood vessels/high-power field [HPF]) compared to Group B (8.867 [±3.258] blood vessels/HPF) ( P = 0.043).
conclusionPre-operative testosterone in proximal hypospadias causes significant changes in penile dimensions and tissue characteristics. Improvement in penile dimensions leads to ease in operability and better tissue handling. However, more studies with large sample size are required to establish the beneficial effects of pre-operative hormone stimulation on urethroplasty.
