Fifty seven female workers at mean age 32 years (range, 23-45 years), employed in a storage battery plant and a capacitor factory were investigated. The lead exposure period was 7.4 years (range, 1-17 years). The retrospective method was used to analyse reproductive functions of women: menses, libido, abortion and delivery. The results were compared with the control group (62 female workers, mean age 32 years; range, 24-45 years). The incidence of polymenorrhea, prolonged and abnormal

The incidence of spontaneous abortions was reported by 6 exposed female workers whereas it was not observed in the control group (p = 0.01). The authors conclude that occupational lead exposure of female workers could lead to the impairment of the functions of reproductive system, however poor working conditions and workload may prove to be additional factors responsible for functional disorders in the subjects under study.
