Fathering children by assisted reproduction linked to increased risk of prostate cancer -- ScienceDaily

After adjusting for factors that could have affected the results, such as age and education level, the researchers found that men becoming fathers through IVF and ICSI had a significantly higher risk of prostate cancer than men who fathered children naturally. Among men achieving fatherhood naturally, 3,244 (0.28%) were diagnosed as having prostate cancer, compared with 77 (0.37%) in the IVF group and 63 (0.42%) in the ICSI group.
