Scientists Warn of Sperm Count Crisis
Biggest-ever study confirms drastic decline in male reproductive health.


December 5, 2012 |


The reproductive health of the average male is in sharp decline, the world's largest study of the quality and concentration of sperm has found.

Between 1989 and 2005, average sperm counts fell by a third in the study of 26,000 men, increasing their risk of infertility. The amount of healthy sperm was also reduced, by a similar proportion.

The findings confirm research over the past 20 years that has shown sperm counts declining in many countries across the world. Reasons ranging from tight underwear to toxins in the environment have been advanced to explain the fall, but still no definitive cause has been found.

The decline occurred progressively hroughout the 17-year period, suggesting that it could be continuing. ...............(more)

2. from 73.6 million sperm per millilitre in 1989 to 49.9 million/ml in 2005.

The proportion of normally formed sperm also decreased by 33.4 per cent over the same period.

Although the average sperm count of the men was well above the threshold definition of male infertility – which is 15 million/ml – it was below the World Health Organisation threshold of 55 million/ml which is thought to lengthen the time to conceive. Other European studies have shown that one in five young men has a sperm count low enough to cause problems conceiving.


wow. to the whole study. interesting. thanks.

Perhaps it's time for humans to fade away and make room for an intelligent species to evolve.

7. Using "Mother Nature" as a personification of biological processes in general...

WE poisoned the environment and our biological processes (i.e., "Mother Nature&quot are reacting to that pollution.

11. Humans! *snarf* Elitist pigs. Intelligent, evolved species to evolve? And just exactly what do

you think we dolphins are?


We dolphins hang out and swim at the beach all day, never work, but always have enough to eat, never poison the earth, never fight wars, the list goes on and on.

You humans think you are so evolved, but y'all work your asses off every day, poison the earth, kill each other daily, etc ad nausem

Examine the two sentences above, and then tell me which sentence indicates the more evolved species?

It should be a total no brainer if y'all are so evolved.
