The aim of this study was to examine time to pregnancy among farmers who used pesticides (traditional farmers) and farmers who did not (organic farmers). A total of 904 men, selected from the Danish Ministry of Agriculture lists of traditional and organic farmers, participated in telephone interviews. The participation rate was 84%. Information was collected on "time to pregnancy" for the youngest child, exposure to pesticides and potential confounders. Using the discrete analogue of the Cox Regression Model (including potential confounders: male and female smoking, female age, parity and contraceptive method), the fecundability ratio between traditional farmers using pesticides and organic farmers was 1.03 (95% CI: 0.75-1.40). In the group of farmers who sprayed with pesticides, none of the characteristics related to the use of pesticides could account for the variation in time to pregnancy. No overall effect of pesticides on male fecundability could be demonstrated in this retrospective study among Danish farmers. |
