Auxetic Expansion of the Tunica Albuginea for Penile Length and Girth Restoration Without a Graft: A Translational Study.
Article in Sexual medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionSeveral conditions can cause penile length and girth loss. Surgical techniques have been used to restore these penile alterations in patients with severe erectile dysfunction during penile prosthesis implantation. One technique uses multiple small incisions in a mesh pattern (similar to a skin mesh) with satisfactory curvature correction without using a graft, however, this technique does not allow simultaneous increase in penile length and girth.
aimTo identify a new surgical technique that increases both the length and girth at the same place on the corpora cavernosa (CC), allowing a simultaneously longitudinal and transverse increase of the tunica albuginea.
methodsA sheet with a star-shaped perforation was created using a mathematical model to allow a longitudinal and transversal increase in the material. Two previously published penile model simulators, with and without deformity, were used to test the mechanical modification of this incision pattern in the CC.
main outcome measureThe effect of the incisions pattern on the geometry of the CC simulator.
resultsThe star-shaped incision (auxetic) simultaneously increased the length, girth, and volume of the CC simulator. This auxetic technique could correct any penile deformity, re-establishing the original penile anatomy. The new auxetic incision is only a conceptual and experimental technique awaiting clinical evidence.
conclusionThe data presented here show that the auxetic technique successfully increases both the length and girth at the same place on the CC simulators, opening a new potential solution to correct challenging cases of complex penile deformities and to restore volume loss.
