The study investigated how certain jobs held by fathers around the time of conception could increase the likelihood of birth defects.
A survey was conducted with 242 cases of congenital malformations and 270 controls, focusing on paternal exposure to hazards like pesticides and solvents.
Findings indicated a significant increase in risk of birth defects linked to fathers exposed to specific workplace hazards, emphasizing the importance of managing these exposures to protect future offspring.
