Ybx1 deficiency impairs spermatid development and male fertility without affecting meiosis in mice: insights into spermatogenesis.
Article in The Journal of reproduction and development, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
Spermatogenesis is a complex process that is required for sperm production. Multiple RNA-binding proteins participate in regulating spermatogenesis. Y-box-binding protein 1 (YBX1) is involved in transcriptional regulation, mRNA stabilization, and translational repression. However, its specific role in spermatogenesis remains unclear. This study investigated the role of YBX1 in spermatogenesis using a Ybx1 conditional knockout (Ybx1 cKO) mouse model. By analyzing the phenotype of Ybx1 cKO mice, we investigated the role of YBX1 in spermatogenesis and male fertility. The morphology and weight of Ybx1 cKO mouse testes were similar to those of wild-type (WT) testes. Sperm count and motility were lower in Ybx1 cKO mice than in WT mice. Histological analysis showed reduced numbers of elongated spermatids in seminiferous tubules and spermatozoa in tubules of the epididymis in Ybx1 cKO mice. Although YBX1 was highly expressed in the cytoplasm of spermatocytes, meiosis progressed normally in Ybx1 cKO spermatocytes. Finally, the fertilization potential of spermatozoa from Ybx1 cKO epididymis was decreased. In conclusion, our results indicate that YBX1 participates in the regulation of spermatid development but is dispensable for meiosis.
