Few risk factors have been established for testicular cancer, but evidence suggests that causal factors operate early in life, perhaps even in utero.
We performed a case-control study to evaluate specific perinatal characteristics as risk factors for the two main histopathologic types of testicular cancer : seminomas and nonseminomas.
Two hundred thirty-two case patients with invasive testicular cancer and 904 individually matched control subjects (all singleton births), nested in a cohort of men born at 10 hospitals in Sweden from 1920 through 1978, were included in the study.
