Low-level lasers can improve spermatogenesis in infertile mice by targeting molecular pathways.

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
Introduction: Infertility affects approximately 15% of couples worldwide, with male factors accounting for approximately half of the cases. Low-level laser therapy (LLLT) has been increasingly considered in modern medicine due to its high efficacy, ease of use, and lack of side effects. Evidence suggests that this method can prevent DNA damage in cells and activate key genes related to fertility. This study aimed to investigate the effects of LLLT on sperm production in azoospermic mice using in vitro and in vivo experimental models. Methods: Adult male NMRI mice (8-9 weeks old, 30-35 g) were divided into the negative control (healthy), positive control (azoospermia via intraperitoneal busulfan, 30 mg/kg), and experimental (azoospermia with 808 nm LLLT at 8 J/cm Results: In vivo, LLLT increased Conclusion: LLLT with a wavelength of 808 nm could improve spermatogenesis and sperm production in a mouse model of busulfan-induced azoospermia in vivo and in vitro. These results demonstrated its potential as a supportive treatment for male infertility.
