Longitudinal Evaluation of Reproductive Endocrine Function in Men With ACTH-Dependent Cushing Syndrome.
Article in The Journal of clinical endocrinology and metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
contextHypogonadism may be caused by Cushing syndrome (CS) and may intensify its adverse consequences.
objectiveThis work aimed to determine the frequency of male hypogonadism before and after curative surgery for CS, and its cause.
methodsPost hoc analyses of prospective cohort studies were conducted at a clinical research center. Study participants were men with adrenocorticotropic hormone (ACTH)-dependent CS: cohort 1 (C1) (n = 8, age 32.5 ± 12 years; studied 1985-1989) and cohort 2 (C2) (n = 44, 42.7 ± 15.1 years; studied 1989-2021). Interventions included the following: C1: every 20-minute blood sampling for 24 hours before and 1 to 40 months after surgical cure. Three individuals underwent gonadotropin-releasing hormone (GnRH) stimulation tests pre and post surgery. C2: Hormone measurements at baseline and 6 and 12 months (M) post cure. Main outcome measures included the following: C1: LH, FSH, LH pulse frequency, and LH response to GnRH. C2: LH, FSH, testosterone (T), free T, free thyroxine, 3,5,3'-triiodothyronine, thyrotropin, and urine free cortisol (UFC) levels and frequency of hypogonadism pre and post surgery.
resultsC1: mean LH and LH pulse frequency increased after surgery (P < .05) without changes in LH pulse amplitude, mean FSH, or peak gonadotropin response to GnRH. C2: 82% had baseline hypogonadism (total T 205 ± 28 ng/dL). Thyroid hormone levels varied inversely with UFC and cortisol. LH, total and free T, and sex hormone-binding globulin increased at 6 and 12 M post surgery, but hypogonadism persisted in 51% at 6 M and in 26% at 12 M.
conclusionHypogonadism in men with CS is widely prevalent but reversible in approximately 75% of patients 1 year after surgical cure and appears to be mediated through suppression of hypothalamic GnRH secretion, and modulated by thyroid hormones.
