BackgroundIdiopathic oligoasthenoteratozoospermia (iOAT) is common among men with infertility, yet patient awareness remains limited. This study assessed their knowledge, attitudes, and practices (KAP) regarding iOAT.MethodsA cross-sectional study was conducted from October 2023 to July 2024 among male infertility patients to assess their KAP regarding iOAT. Demographic information and KAP data were collected through questionnaires administered to male infertility patients.ResultsA total of 467 valid responses from male infertility patients were included in the final analysis (effective response rate 93.4%). Male infertility patients exhibited inadequate knowledge (median 17, IQR 13-20), generally positive attitudes (median 35, IQR 31-38), and suboptimal practices (median 18, IQR 16-20). Correlation analysis revealed significant positive correlations between knowledge and attitude (r = 0.287, P < 0.001), knowledge and practice (r = 0.293, P < 0.001), and attitude and practice (r = 0.266, P < 0.001).ConclusionMale infertility patients demonstrated inadequate knowledge, generally positive attitudes, and suboptimal practices concerning iOAT, with educational level and income significantly influencing their KAP outcomes.
