title: [Study on environmental and psychological risk factors for female infertility].
abstract: OBJECTIVE
  To investigate the environmental and psychological risk factors for female infertility and to provide a scientific basis for the prevention and control of female infertility.
  
  
  METHODS
  In a hospital-based case-control study, a self-designed questionnaire was used to survey the cases and controls (1:1) with nation and age (± 2 years) as matching variables. Univariate and multivariate conditional logistic regression models were employed to analyze the datasets.
  
  
  RESULTS
  The univariate analysis showed that female infertility was related to the following factors: eating fried foods, alcohol consumption, smoking, staying up late, perm, housing decoration, contact with heavy metals, exposure to radiation, contact with pesticides, working in hot environment, mental stress, uneasiness, helplessness, and despair. The multivariate analysis showed that staying up late (OR = 2.937), housing decoration (OR = 2.963), exposure to radiation (OR = 2.506), contact with pesticides (OR = 2.908), and mental stress (OR = 4.101) were the main risk factors for female infertility. Furthermore, there was an interaction between staying up late and mental stress.
  
  
  CONCLUSIONS
  Female infertility is caused by multiple factors including staying up late, housing decoration, exposure to radiation, contact with pesticides, and mental stress, and there is an interaction between staying up late and mental stress.
