Causes of infertility as predictors of subsequent cancer risk

Large retrospective cohort study investigating whether different causes of infertility (endometriosis, anovulation, tubal disease, male factor, cervical/uterine disorders) predict future cancer risk among 12,193 women who sought infertility treatment at five U.S. reproductive endocrinology practices between 1965 and 1988, with cancer incidence tracked through 1999.
