Osteocalcin improves testicular morphology but does not ameliorate testosterone synthesis signaling in azoospermic mice.
Article in Clinical and experimental reproductive medicine, 2024. 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
objectiveOsteocalcin (OCN) influences spermatogenesis in conjunction with testosterone and estrogen. OCN facilitates the secretion of testosterone by engaging with G protein-coupled receptor class C group 6 member A (GPRC6A) on Leydig cells and with androgen receptors on Sertoli cells.
methodsAdult mice were assigned to the following groups: control; sham I, which received dimethyl sulfoxide for 5 weeks followed by phosphate-buffered saline for 1 month; azoospermia, which was treated with busulfan (40 mg/kg); sham II, which consisted of azoospermic animals that received phosphate-buffered saline for 1 month beginning at the 5-week mark; and the experimental group, which included azoospermic mice treated with OCN (3 ng/g/day) for 1 month.
resultsIn the mice receiving OCN treatment, immunohistochemical analysis revealed increased expression of androgen receptors and GPRC6A, indicative of enhanced spermatogenesis. Additionally, the expression levels of the cyclic adenosine monophosphate-responsive element binding protein 1, steroidogenic acute regulatory protein, and cytochrome P450 family 11 genes were elevated. However, testosterone levels exhibited no significant differences across groups. Morphometric analysis suggests that OCN may play a crucial role in spermatogenesis, as evidenced by its positive effects on germinal cells and the germinal epithelium in the azoospermia group (p<0.05).
conclusionWe conclude that OCN may serve as a beneficial therapeutic agent for male infertility.
