Objectives  To explore influencing factors for the reproductive health of male greenhouse workers and to provide references for promoting their reproductive health.

Methods  Three hundred and fifty-six male greenhouse workers were investigated by questionnaire survey; and logistic regression analysis was used to analyze the relationships of the basic information of workers, cultivated area of greenhouse, frequency of using pesticide with the reproductive health of male workers.

Results  The risk factors of enhancing dysaphrodisia were the longer interval time between spraying pesticide and taking shower in winter, while the protective factors were mixing pesticide in a right way and wearing protective clothing. The occurrence of erectile dysfunction was correlated with the interval time between taking shower and spraying pesticide in winter. The danger of ejaculation disorder was increased with longer working time in greenhouse each year; and longer interval time between spraying pesticide and taking shower in winter, the danger was decreased with wearing protective clothing and hat while working. The important risk factors for sexual orgasm and sexual satisfaction obstacles was less interval time between spraying pesticide and taking shower in summer and longer time of spraying pesticide during a year.The risk factor for theoccurrence of prostatitis was less interval time between spraying pesticide and taking shower in winter, while the protective factor was wearing protective clothing. For prostatic hypertrophy, the protective factors included the longer interval time to return to greenhouse after spraying pesticides. The risk factor for prostatic hyperplasia was related to the planting pattern in greenhouse.

Conclusions  The exposure intensity, spraying methods and protective measures for using pesticide are the main influencing factors related to the reproductive health of male greenhouse workers.
