ObjectiveTo explore the risk factors for male infertility and their influences on sexual life quality. MethodsA total of 112 male infertility patients admitted to our hospital from January 2018 to December 2019 (infertility group) and 98 married males (control group) who underwent health examinations in our hospital during the same period were selected as the research objects. Field questionnaire surveys were conducted on the two groups to compare the differences in age of marriage, education level, smoking, staying up late, etc. between the two groups. Multivariate logistic regression analysis was performed on the risk factors for male infertility. The influences of independent risk factors for male infertility on sexual life quality of patients with male infertility were analyzed. ResultsThere were statistically significant differences in the marriage age, education level, BMI, passive smoking, drinking, sleeping time, computer use time, spousal relationship, and the history of sexually transmitted diseases between the infertility group and the control group (P＜0.05). The results of multivariate logistic regression analysis showed that BMI, passive smoking, drinking, sleeping time, computer use time, and the history of sexually transmitted diseases were independent risk factors for male infertility. There was a statistically significant difference in the sexual life quality scores between male infertility patients with different sleeping time and with the presence of the history of sexually transmitted diseases (P＜0.05). ConclusionBMI, passive smoking, drinking, sleeping time, computer use time, and the history of sexually transmitted diseases are independent risk factors for male infertility. Sleeping time and the history of sexually transmitted diseases have important influences on sexual life quality of patients.
