Oxidative Stress Induces Changes in Molecular Markers Associated with Ferroptosis in Human Spermatozoa.
Article in The world journal of men's health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeFerroptosis is a type of iron-dependent regulated cell death characterized by increased bioavailability of redox-active iron, loss of GPX4 antioxidant capacity, and oxidation of polyunsaturated fatty acid-containing phospholipids mediated by reactive oxygen species (ROS). The aim of this study was to evaluate the effect of oxidative stress induced by arachidonic acid (AA) on ferroptotic cell death in human spermatozoa. MATERIALS AND
methodsSpermatozoa from normozoospermic donors were exposed to AA (5, 25, and 50 µM) for 1 hour at 37 ℃, including an untreated control. Oxidative stress was confirmed by evaluation of cytosolic and mitochondrial ROS production, viability, mitochondrial membrane potential (ΔΨm) and motility. Subsequently, molecular markers of ferroptosis including iron content, levels of GPX4, SLC7A11, ACSL4, IREB2 and lipid peroxidation were evaluated. The analyses were carried out using either flow cytometry, a microplate reader or confocal laser microscopy.
resultsAA-induced oxidative stress showed increased cytosolic and mitochondrial ROS production accompanied by impaired ΔΨm, viability and motility in human spermatozoa. These results were associated with biochemical and molecular markers related to ferroptotic cell death including an increase in iron content in the form of ferrous (Fe²⁺) ions, SLC7A11, ACSL4, IREB2, a decrease in the level of GPX4, and an increase in the level of lipid peroxidation compared to the untreated control.
conclusionsThis study revealed that AA-induced oxidative stress induces cell death with biochemical characteristics of ferroptosis in human spermatozoa, demonstrating another mechanism of alteration of sperm function induced by oxidative stress and could establish new therapeutic objectives to prevent the decrease in sperm quality mediated by oxidative stress.
