Title Time-to-pregnancy among male greenhouse workers
Bibliographic information Mar. 2008, Vol.65, No.3, p.185-190. Illus. 21 ref.
Abstract The aim of this study was to determine whether time-to-pregnancy (TTP) is prolonged in 694 male greenhouse workers exposed to pesticides in comparison with 613 non-exposed controls. Data were collected through self-administrated questionnaires with detailed questions on TTP, as well as on lifestyle (smoking habits, coffee and alcohol consumption, etc.), work tasks, and occupational exposures of the men and their partners in the six months before conception of the most recent pregnancy. TTP was compared between male greenhouse workers and non-exposed controls. The crude analyses did not show a decreased overall fecundability among greenhouse workers compared to the non-exposed reference group. However, when fecundability was assessed for primigravidous couples, duogravidous couples, and multigravidous couples separately, greenhouse workers were found to be less fecund when trying to conceive their first pregnancy. Among couples who already experienced one or more pregnancies, no association was seen between pesticide exposure and TTP after adjustment for confounders.
