By Jorma Toppari, Turku University led researchers examined three cohorts of 19-year-old men between 1998 and 2006. The men, the late 1980s the late 1980s had lower sperm counts than those who were born in the early 1980s. The total sperm count was 227 million, are 202 and 165 for men born in 1979-81, 1982-83 and 1987. Less than 10 percent of sperm are structurally normal, and the number of morphologically normal sperm declined from 18 million to 11.

The underlying cause for these simultaneously occurring adverse trends remains unknown. However, the rapid change strongly points to environmental reasons. Endocrine disrupting compounds during development have established the hypothesis that be a cause. – ‘Our results further required efforts to identify the reasons for the adverse trends in reproductive health, preventive measures possible’Toppari notes.Kristin Getter and fellow indicate in the new study to green roofs have multi-functional. They reduce heating and air conditioning expenses, for example and keep and retain storm water. Researcher knew green roof absorb carbon, a major greenhouse gas, medium warming but nobody had measure the effects until now.
