Objective To investigate the sexual function and reproductive outcomes of male workers occupationally exposed to CS2, and to provid a scientific basis for interference.
Methods In a retrospective study, the basic information, sexual function and reproductive outcomes of 276 workers exposed to CS2 were collected through a self-administered questionnaire, in which 132 male workers exposed to CS2 but their wives did not were set as single exposure group, 144 male workers and their wives both exposed as mixed exposure group. Another 126 unexposed male workers set as control.
Results The sexual function investigation showed that male workers in both exposure groups who aged under 40 and exposed more than 10 years had sexual unsatisfactory, decreased number of sex, and increased sex aversion (P < 0.05). The rate of pregnancy complications of the wives in all groups had no statistical significance (P > 0.05). The rate of spontaneous abortion in the mixed exposure group was significantly different from single exposure and control groups(P < 0.05). The rate of low birth weight infants of the mixed exposure group had significant difference compared with the control group (P < 0.05).Offsprings' intelligence and physical development had no significant difference in all groups (P > 0.05).
Conclusion A long term and low level of CS2 exposure had an effect on the attitude and frequency of sex life of male workers, and may result in bad reproductive outcomes as well. But there were no significant changes of development in offsprings.
