Although prenatal factors are associated with testicular cancer etiology, few studies have examined the reproductive profiles of men prior to diagnosis. This case--control study investigated fertility patterns prior to testicular cancer diagnosis by comparing pregnancies fathered by 201 men with testicular cancer and those fathered by 204 age- and neighborhood-matched controls. Regardless of histology, men with testicular cancer were less likely to have ever fathered a live-born infant (OR 0.67, 95% CI 0.42--1.06) and had fewer offspring than control men (means 1.8 and 2.1, respectively). Cases were more likely than controls to report having an infertility diagnosis (OR 9.47, 95% CI 1.19--75.2) or a low sperm count (OR 5.85, 95% CI 1.28--26.7) prior to cancer diagnosis. No differences were observed for pregnancy loss. These results indicate that men with testicular cancer may have impaired fecundity and fertility as evidenced by an infertility diagnosis or low sperm count and fewer live births. Further research is needed to determine the extent to which reproductive factors are involved in the etiology of testicular cancer.
