Indeed, according to the Independent there is a crisis regarding fertility rates. But rather interestingly the same trend has not been observed in other parts of the world such as South America, Africa, Asia, though admittedly fewer studies have been carried out in those areas.
Also, it is indeed true that one of the suspected factors, along with pesticides, stress, smoking, obesity, is chemicals in the environment. But most important to note is the fact that further research is still required before anything conclusive can be ascertained.
Sperm counts have plunged by nearly 60 per cent in just 40 years among men living in the West, according to a major review of scientific studies that suggests the modern world is causing serious damage to men’s health.
Pesticides, hormone-disrupting chemicals, diet, stress, smoking and obesity have all been suggested as possible reasons behind the dramatic declines but experts say more research is urgently needed
The same trend was not seen in other parts of the world such as South America, Africa and Asia, although the scientists said fewer studies had been carried out there.
However, given that one of the biggest factors that separate different cultures is diet, it may come as no surprise that one of the main theories for the cause of lowering fertility rates is dietary, according to a recent study of 2,935 men, reported by NCBI.
In a cross-sectional study of 2935 young Danish men unaware of their fertility status, higher adherence to the Western diet pattern was associated with lower sperm quality than that of men with the lowest adherence. Conversely, higher adherence to the prudent diet pattern was associated with higher sperm quality.
These findings suggest that adherence to healthy diet patterns, a potentially modifiable lifestyle factor, is associated with better semen quality and potentially more favorable fertility potential among young men.
Are chemicals in plastic causing a fertility crisis?
Nothing conclusive can be ascertained until further research is carried out. But certainly chemicals are believed to be one of the many hazards, with diet perhaps currently being taken very seriously.
Currently there is no reason to believe that chemicals in plastic are the only factor, nor even necessarily the main factor.
Like Prof. Allan Pacey, Professor of Andrology, University of Sheffield, said to the Science Media Centre, it is too premature to conclude that this is due to man-made chemicals. (Not a direct quote - words to that effect)
“Interestingly, the paper concludes that the sperm counts may have seen the greatest decline in the post industrial countries of North America, Europe and Oceania compared to others in Asia, South America and Africa. However, while it would be easy to conclude that this represents a real global difference, perhaps driven by greater exposure of pregnant women or adult men to more man-made chemicals, I think it is too premature to make this conclusion.
