chemicals adversely affect reproductive ability. This study examined the
possible association between employment in the plastics industry and
infertility. Dynamic cohorts of economically active women and men were
followed for hospital contacts due to infertility in the Danish
Occupational Hospitalisation Register, from 1995 to 2005. A person was
considered to be at increased risk in a particular year if plastic work was
the main occupation in the previous year. Analyses were standardized
according to county, socio-economic group, year and age. 107 cases of
treatment for female infertility were observed among female plastic
workers, as opposed to an expected 87.15 cases, i.e. relative risk was 1.23
(95% CI: 1.01-1.48). For male workers the numbers were 41 respectively 49.9
cases, with relative risk being 0.82 (95% CI: 0.59-1.11). The increased
incidence of infertility treatment in female plastics workers motivates
more specific studies of reproductive occupational health in the plastics
