Guilu erxian glue improves sperm quality in oligasthenospermia mice by promoting TDRP methylation and regulating the cAMP/PKA pathway.
Article in Scientific reports, 2025. 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
Oligoasthenozoospermia (OAS) is a common cause of male infertility, and Guilu Erxian Glue (GLEXG) is a traditional Chinese medicine known to improve male reproductive function. The role of GLEXG in OAS and its mechanism of action are not well understood. After the OAS model was established with Tripterygium wilfordii polyglycoside (GTW)-induced mice, the mice were orally administered GLEXG. The effects of GLEXG on testis and epididymis of GTW-induced mice were evaluated by HE, TEM, and Johnson scores. Meanwhile, the effects of GLEXG on semen quality of GTW-induced mice were explored by CTC staining and sperm viability assay, etc. Additionally, an H2O2-treated mouse spermatogonial (GC-2) cell model was established and incubated with GLEXG-containing serum. The mechanism of action of GLEXG was investigated by immunofluorescence, methylation-specific PCR (MSP), and western blot. The OAS mouse model was successfully constructed, and the testes, epididymis, and semen quality of mice were improved after GLEXG treatment. In vivo, GLEXG could promote the expression of TDRP, cAMP, and PKA, and the methylation levels of TDRP genes. Mechanistically, GLEXG could improve sperm viability in H
