The role of thiol/disulfide homeostasis in unexplained primary infertile patients: A prospective cohort study.
Observational study in Medicine, 2025. 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
backgroundOur study aims to investigate whether there is a relationship by measuring the total oxidant/antioxidant load with the thiol/disulfide method in patients with unexplained infertility.
methodsA total of 82 participants were enrolled, consisting of 41 women with unexplained infertility and 41 fertile controls matched for age and body mass index (BMI). Hormonal profiles, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), thyroid-stimulating hormone (TSH), and prolactin, were assessed using the chemiluminescence immunoassay method. Thiol/disulfide homeostasis was evaluated using a validated automated spectrophotometric method, which measured native thiol (NT), total thiol (TT), and disulfide levels. Detailed quality control measures ensured the reliability of the results.
resultsIn the study, no significant difference was found between the infertile and fertile groups' demographic (age) and clinical variables in terms of height, weight, BMI, FSH, LH, E2, TSH, prolactin, antral follicle count, TT, NT, and disulfide values (P > .05). The rates were found to be greater in the infertile group in disulfide/NT ratio and disulfide/TT ratio compared to the fertile group, even though there was no statistically significant difference between the groups' disulfide/NT ratio, disulfide/TT ratio, and NT/TT ratio values. The fertile group, however, had a higher NT/TT ratio rate.
conclusionAlthough the unexplained infertility and fertile groups in the study did not differ in serum thiol and disulfide levels, the infertile group was found to have a relatively high disulfide/thiol ratio. More prospective studies on thiol/disulfide balance related to unexplained infertility may help to understand the relationship.
