    Abstract : The aim of this thesis was to search for causes of the testicular cancer epidemic through epidemiologic studies of testicular cancer and possibly related conditions, such as urogenital birth defects and subfertility. First, we assessed changes in fertility over time by studying time-to-pregnancy among primiparous women in Sweden from 1983 through 1993 using data from the Medical Birth Registry. READ MORE

    Abstract : The purpose of the present thesis was to evaluate Trichopoulos' hypothesis that breast cancer can originate in utero, and to examine the role of antenatal estrogen exposure in the etiology of testicular cancer. First, we used data from a Swedish-Norwegian cohort study on risk factors for small-for-gestational-age births to identify markers for antenatal estrogen exposure. READ MORE
