Spermatogenesis is one of the few examples of non pathological cell proliferation in the adult mammal organism. Disorders in the spermatogenesis may indicate proliferation disorders in general. A previous study showed a higher mortality of men with subnormal sperm counts. Now we study associations between sperm parameters and - specific mortality. Two broad cause-of-death classes may have higher incidence among subfertil men: proliferation disorders and risky behavior which is more prevalent in childless men. We analyze death certificates of 386 men with normal and low sperm counts measured in the outpatient facility of the Department of Andrology at Marburg University Hospital from 1949 onwards. The first results show no differences between the fertility-groups regarding the prevalence of cancer, cardio vascular disease, outcome of risky behavior or any other cause of death.
