In vitro effect of granulocyte-macrophage colony-stimulating factor (GM-CSF) on the expression of genes related to sperm motility and energy metabolism and intracytoplasmic sperm injection outcomes in obstructive azoospermic patients.
Article in Molecular biology reports, 2024. 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 4 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
backgroundThe presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) and its receptor in various testicular cells and spermatozoa suggests a potential role in enhancing spermatogonial and postmeiotic cell development. Moreover, GM-CSF activates the pivotal pathways implicated in sperm motility regulation and glucose metabolism. However, the impact of GM-CSF on testicular biopsies from patients with obstructive azoospermia (OA) remains unexplored. Therefore, this study aimed to investigate the in vitro effects of GM-CSF on the expression of genes related to glucose transporters and signaling pathways, sperm motility, and viability in testicular biopsies. METHODS AND
resultsFollowing testicular sperm extraction from 20 patients diagnosed with OA, each sample was divided into two parts: the experimental samples were incubated with medium containing 2 ng/ml GM-CSF at 37 °C for 60 min, and the control samples were incubated with medium without GM-CSF. Subsequently, the oocytes retrieved from the partner were injected with sperm from the treatment and control groups. The sperm parameters (motility and viability), the expression levels of sperm motility-related genes (PIK3R1, PIK3CA, and AKT1), and the expression levels of sperm energy metabolism-related genes (GLUT1, GLUT3, and GLUT14) were assessed. Furthermore, the fertilization and day 3 embryo development rate and embryo quality were evaluated. Compared with those in the nontreated group, the motility parameters and the mRNA expression levels of PIK3R1, AKT1, and GLUT3 in testicular sperm supplemented with GM-CSF were significantly greater (p < 0.05). However, no significant differences in the mRNA expression of PIK3CA, GLUT1, or GLUT14 were detected. According to the ICSI results, compared with the control group, the GM-CSF treatment group exhibited significantly greater fertilization rates (p = 0.027), Day 3 embryo development rate (p = 0.001), and proportions of good-quality embryos (p = 0.002).
conclusionsGM-CSF increased the expression of genes related to motility and the energy metabolism pathway and effectively promoted the motility of testis-extracted spermatozoa, consequently yielding positive clinical outcomes.
