Brief Summary
The incidence of testicular germ cell tumors, the most common cancer in men aged 15 to 45 years, has doubled in France in 30 years. Reasons remain unclear but a role of environmental factors, especially during critical periods of development, is strongly suspected. Reliable data on environmental exposure during this critical period are sparse.The discordant findings and the limitations of available studies underline the importance to conduct studies with sufficient statistical power to detect risk due to exposures during critical windows of vulnerability. We conduct a multicentric case-control study to assess this association. Cases and controls will be enrolled during a 18-month period. They will be interviewed by professional telephone interviewers about their occupational and residential history and about their domestic exposure to pesticides and other nuisances. An optional biological study to assess genetic polymorphisms known to be associated with testicular cancer will be proposed to every cases and controls. Mothers (or close relative) of cases and controls will also be contacted (with son's agreement). If they agree to participate, they will also be interviewed about antenatal and early life exposure of their sons to pesticides and other nuisances. Cases will be matched up with 2 controls (one of each group) both on age (+/- 2 years) and on recruiting center.

Outcome Measures
Primary Outcomes (1)
Assess the association between pesticide exposure during Antenatal and Early Postnatal Periods and the risk of testicular cancer during adulthood
Occupational, environmental and domestic exposures to pesticides and other nuisances will be assessed.
at the end of enrollment (18 months)
Secondary Outcomes (2)
Assess the association between a combined exposure to pesticides and the risk of testicular cancer during adulthood
at the end of enrollment (18 months)
Analyse polymorphisms known to be associated with testicular cancer risk to explore gene-environment interactions
one year after the end of enrollment
Study Arms (3)
Cases: testicular cancer patients
Group A controls
Sperm donors and husbands of women with fertility disorders All controls must have a normal spermogram
Group B controls
Husbands of women with a pathological pregnancy
Interventions
Subjects will be interviewed about environmental, domestic and occupational exposures during several periods of life Two blood samples will be collected at enrollment to study genetic polymorphisms
Eligibility Criteria
Cases are patients with a testicular germ cell tumor. They will be recruited in the French infertility centers at the moment of sperm cryopreservation. Group A controls are sperm donors and husbands of women with fertility troubles. They will be recruited in the French infertility centers and in the medically assisted procreation centers. Group B controls are husbands of women followed for a pathological pregnancy. This group of controls will be recruited in the level III maternities.
