Synthetic Cannabinoid AB-FUBINACA Negatively Impacted the Male Fertility and Induced Testicular Toxicity.
Article in Forensic toxicology, 2026. 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
purposeThe recreational use of synthetic cannabinoids (SCs) by adolescents and adults has markedly increased in recent years. Previous studies demonstrated that exposure to SCs is associated with multiple adverse health effects. Nevertheless, little is known about the effects of these substances on male fertility. The current study aimed to investigate the toxicological effects of subacute exposure to synthetic cannabinoid AB-FUBINACA on male reproductive system in mice.
methodsAdult male Balb/c mice received daily intraperitoneal injections of various doses of AB-FUBINACA (0.75, 1.5, and 3 mg/kg for 3 weeks). Using biochemical and molecular methodologies, the impact of AB-FUBINACA on serum levels of reproductive hormones, sperm viability as well as various parameters in testicular tissue were evaluated.
resultsOur findings demonstrated that AB-FUBINACA induces dose-dependent reduction in testosterone levels in the serum, but not in follicle-stimulating hormone or luteinizing hormone. AB-FUBINACA treatment also causes a significant dose related decrease in sperm viability. These findings were associated with higher level of oxidative stress (GP91 expression and malondialdehyde level) and elevated expression of key regulators of apoptosis (Bax and caspase-3) as well as reduced expression of mitochondrial respiratory chain complexes SDHB (II), UQCRC2 (III), and ATP5a (V) in the testicular tissue.
conclusionFrom these findings, it can be concluded that exposure to AB-FUBINACA can interfere with the normal physiology and functioning of the male reproductive organs. Hence, gaining insight into the mechanisms by which SCs interfere with male fertility could guide future interventions and treatments.
