Assessment of Associations Between Demographic Characteristics, Lifestyle Factors, and Sperm Quality Among Men Presenting With Infertility Complaints.
Article in Health science reports, 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
Background and Aim: Infertility is a significant global health concern affecting couples worldwide, with male factors contributing to approximately half of all cases. Given regional variations in reproductive determinants, location-specific evidence from clinic-based populations is essential to inform targeted clinical assessments and local public health strategies. The primary objective of this study was to evaluate the statistical associations between demographic characteristics, clinical history, and lifestyle factors with sperm quality parameters in men attending a regional infertility referral center. Methods: This descriptive-analytical cross-sectional study was conducted on 200 men who were referred to Lorestan University of Medical Sciences. The data collection tool included a researcher-made checklist consisting of four sections on individual demographic information, information and clinical records, one's lifestyle information, and information on the results of sperm testing that were collected from the individual's file. The information was then entered into SPSS 22 and was analyzed. Results: The average age of participants was 34.12 ± 6.45 years, ranging from 23 to 55 years. Among them, 60.5% were employed, 84.5% lived in cities, and 42% had an undergraduate education. Twenty percent had a history of chemical exposure or factory work, 25.5% smoked, 7% consumed alcohol, and 8% had sexual disorders. A significant inverse association was observed between age and age at marriage with sperm morphology ( Conclusions: Therefore, this study concludes that older age at marriage negatively impacts sperm quality. This study suggests that a later age at marriage is associated with lower sperm morphology and that certain clinical and lifestyle factors are associated with statistical differences in sperm parameters, particularly motility. These exploratory patterns underscore the necessity of accounting for demographic and behavioral variables during clinical assessments.
