On this call, Dr. Skakkebaek presented his concerns about increasing trends in male reproductive disorders, including the significant global increase in incidence of germ cell tumors. He and colleagues from all over the world demonstrated that over half of all young men’s semen quality does not meet the reference standard of the World Health Organization.
Dr. Skakkebaek presented evidence linking testicular cancer, poor semen quality, childlessness, and rapidly decreasing fertility rates. He showed how there is little doubt that environmental factors, most likely associated with modern lifestyles, have – in a broad sense – had an adverse influence on male reproductive health. He and his group are examining a fundamental role that exposure to endocrine-disrupting chemicals may play in these trends, trends that in a few decades will result in decreasing populations in industrialized countries, and believes collaborative research is required to identify the causes of these adverse trends.
