Epidemiology and occupational risk factors of male infertility based on 3,025 patients in Eastern Morocco during 2021-2023: a cohort study.

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
objectiveThe objective of our study was to characterize the sperm parameters of men consulting for infertility in our fertility center.
methodsThe study included 3,025 patients investigated from September 2021 to July 2023. Demographic data, infertility risk factors, and the primary or secondary nature of infertility were recorded for each patient. The sperm parameters were analyzed according to World Health Organization (WHO) criteria (2021).
resultsThe average age of the patients was 40 years. The average duration of infertility was 5.5 years. Primary infertility was noted in 2,736 patients (88.97%). The most common risk factors for infertility were occupational exposure, followed by varicocele. Lifestyle factors associated with male infertility included smoking (24.29%), alcohol consumption (12.49%), and high temperature exposure (30.08%). Spermogram abnormalities were observed in 78.71% of cases. Spermocytogram abnormalities were found in 63.1% of cases. Sperm count, morphology, total motility, and vitality below WHO (2021) reference values were found in 25.60%, 34.13%, 32.29%, and 62.46% of the analyzed samples, respectively. Seminal fluid analysis revealed oligozoospermia in 29.07% of cases, asthenozoospermia in 24.68%, and azoospermia in 17.56%. Oligo-astheno-necrospermia was the most frequently observed combined abnormality (10.0%).
conclusionThis study showed a high rate of abnormal semen quality in male partners of infertile couples. Male infertility is often multifactorial and results in quantitative and/or qualitative sperm abnormalities.
