Quote: A comprehensive study into the reproductive health of 26,600 men found sperm concentration has decreased by a third since the 1990s.
The findings are so significant experts have warned action must now be taken to avoid significant fertility problems and the average family size decreasing.
The study, which was carried out in France, found there had been a ''significant and continuous'' 32.2 per cent decrease in sperm concentration over 17 years.
Numbers of sperm per millilitre of semen fell at about two per cent a year between 1989 and 2005, with researchers calculating the average 35-year-old man would see his sperm count reduced from around 73.6 million per millilitre of semen to 49.9 million.
At the same time, the proportion of normally formed sperm declined by about a third.
Now, they're not sure what's causing this, but the scientific consensus seems to be:
Quote:Something in our modern lifestyle, diet or environment is causing this and it is getting progressively worse. We still do not know which are the most important factors but the most likely are … a high-fat diet and environmental chemical exposures."
Sounds plausible, but Swedish news went into some very interesting details:
According to Swedish National News svt.se , a similar study was conducted in 2000 in Sweden where no decline in sperm count was detected.
This is getting more interesting, the Swedish study was done in southern Sweden (Scania)
This is especially interesting considering how close the Southern part of Sweden is to Denmark.
Quote:The Sound (Danish Øresund, Danish pronunciation: [ˈøːɐsɔnˀ], or Swedish Öresund, pronounced [œrəˈsɵnd]), locally known as Sundet, is the strait that separates the Danish island Zealand from the southern Swedish province of Scania. Its width is just 4 kilometres (2.5 mi) at the narrowest point between Kronborg Castle at Elsinore (Helsingør in Danish) in Denmark, and the northern harbour of Helsingborg in Scania, Sweden. The strait has also lent its name to the Øresund Region of 3.8 million inhabitants on both the Danish and Swedish sides.

In fact, historically speaking, Finland has been a part of the Swedish kingdom longer than Skåne, which belonged to the Danes up till 1658. So there shouldn't be a genetic difference.
But there's a big difference in sperm quality between these locations...
Turns out Danish men's sperm count was 40 per cent lower than the Swedish men's.
The article goes on to say that the relation between low sperm count and testicular cancer has been scientifically established and that it's twice as occurring across the Straits (Denmark) than in Sweden.
The article also says that Finnish men have the highest sperm count.
All pesticides allowed anywhere in Europe are used here as well, I find it hard to believe our agricultural practices differ much from anywhere else in Europe. On top of that, Finns are not exactly known for a low fat diet.
Anyway, I found this very interesting and puzzling.
