Protective Effect of B1 and B12 Vitamins on Post-Thaw Sperm Quality Parameters and Seminal Plasma Antioxidant Status in Rams.
Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundSperm membranes, rich in polyunsaturated fatty acids, are highly susceptible to lipid peroxidation. Oxidative stress significantly impacts sperm function, and B-group vitamins play a crucial role in mitigating this damage.
objectiveThis study investigated the effects of vitamins B1 (VitB1) and B12 (VitB12) on sperm quality and seminal antioxidant status following cryopreservation in Arabi rams.
methodsSemen was collected from 10 Arabi rams and pooled. The pooled semen was diluted and cryopreserved with varying concentrations of VitB1 and VitB12 (0, 0.5, 1, 2 and 4 mg/mL). Post-thaw sperm quality parameters, including motility, viability, membrane integrity and morphology, were assessed. In addition, seminal antioxidant enzyme activities and lipid peroxidation were evaluated.
resultsSupplementation with 1 mg/mL VitB12 and 0.5-1 mg/mL VitB1 significantly enhanced post-thaw sperm motility, viability, membrane integrity and morphology. This was accompanied by a reduction in malondialdehyde (MDA) levels. The highest total antioxidant capacity (TAC) was observed with 1 mg/mL VitB12 and 0.5 mg/mL VitB1 (p < 0.05), positively correlating with sperm motility and viability (p < 0.01). Glutathione peroxidase (GPx) activity was highest in the 1 mg/mL VitB12 and VitB1 groups and negatively correlated with sperm abnormalities (p < 0.01). Catalase (CAT) activity significantly increased in the 1-2 mg/mL VitB12 and 0.5-2 mg/mL VitB1 groups, positively correlating with sperm progressive motility and viability (p < 0.01).
conclusionsThese findings demonstrate that incorporating 1 mg/mL VitB12 and 0.5 mg/mL VitB1 into the cryopreservation extender effectively mitigates oxidative stress, enhances antioxidant defences and improves post-thaw semen quality in Arabi rams.
