However, considering that anticancer drugs can induce genetic lesions in germ cells that may transmit abnormalities to offspring (M. Auroux and E. Dulioust, Behav. Brain Res., 16:

Sixty couples who had sought medical advice for infertility of more than 12 months duration (cases) were compared with 165 couples who had had a child (controls). All the men in these couples had been employed by the military. The infertility risk factors studied were male and female medical factors, occupational and environmental exposures. We obtained age-adjusted odds ratios of 7.4 [95% confidence interval (CI): 1.4-39.5] for testis surgery, and 13.0 for varicocele (95% CI: 1.4-120.3) in men. In logistic regression, the age-adjusted odds ratio for men who had worked in a nuclear submarine was found to be 2.0 (95% CI: 1.0-3.7), and that for heat exposure was 4.5 (95% CI: 1.9-10.6). One limitation of this study is the lack of exposure measurements, especially for potential exposure to nuclear radiation (type of reactor used in nuclear-powered submarines, inability to obtain personal dosimeters worn by military personnel working in nuclear submarines). In conclusion, this study suggests that in this military population, having worked as a submariner in a nuclear-powered submarine, and having worked in very hot conditions, should be considered as risk factors for infertility.

It also set the needs of the actors of the National System of Science and Technology and drove education to begin in diverse fields. However, universities, research centers and consulting services have stopped the investigation of Technology Management tools and they have preferred to apply the knowledge in the field. The lack of investigation in new managerial abilities like innovation strategies, technological plans and technological assessment, among others, has led them to a phase of maturity, which has resulted in the complete lack of innovation in these tools. The abandonment of the investigation in such managerial strategies has triggered the birth of this investigation, which aims to uncover the most important topics in the area of Technology Management for 2020.
