Reversible congenital hypogonadotropic hypogonadism: keys for clinical management.
Review in Archives of endocrinology and metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Congenitalhypogonadotropic hypogonadism (CHH) is characterized by absent/incomplete puberty and a treatable form of male infertility resulting from deficient gonadotropin-releasing hormone (GnRH) secretion/action. Traditionally, CHH has been considered a permanent, lifelong condition. However, evidence indicates a subset men undergo reversal and recover reproductive axis function. We conducted a structured literature search (Medline, PubMed) using keywords to retrieve articles on CHH reversal (1975-2025). We synthesize the literature to provide a high-level overview of CHH and the reversal phenomenon in males. Particular focus is given to clinical aspects of CHH and reversal using a case vignette to highlight keys to management. Approximately 10-15% of males with CHH undergo reversal with sustained normalized testosterone levels and spermatogenesis off treatment. A key sign of reversal is testicular growth while on testosterone replacement therapy. Those men with some degree of spontaneous puberty (i.e., larger testicular volume), detectable follicle stimulating hormone levels , and/or pathogenic variants in GNRHR are more likely to undergo reversal. In contrast, severe GnRH deficiency, pathogenic ANOS1 and/or two or more combined pathogenic variants (oligogenicity) in CHH genes are less likely to recover reproductive axis function. Reversal is not lasting in all cases. The reversal phenomenon challenges the classical dogma that CHH is permanent and lifelong. Reversal cases highlight the plasticity of the neuroendocrine control of reproduction. Clinicians can tailor the approach to men with CHH using reversal predictors to guide supervise washout to identify reversal as well as long-term monitoring to assess potential relapse.
