Sperm Counts Among Western Men Have Halved In Last 40 Years, Says Study (theguardian.com)
New submitter flote shares a report from The Guardian: Sperm counts among men have more than halved in the last 40 years, research suggests, although the drivers behind the decline remain unclear. The latest findings reveal that between 1973 and 2011, the concentration of sperm in the ejaculate of men in western countries has fallen by an average of 1.4% a year, leading to an overall drop of just over 52%. The study, published in the journal Human Reproduction Update by an international team of researchers, drew on 185 studies conducted between 1973 and 2011, involving almost 43,000 men. The team split the data based on whether the men were from western countries -- including Australia and New Zealand as well as countries in North America and Europe -- or from elsewhere. After accounting for factors including age and how long men had gone without ejaculation, the team found that sperm concentration fell from 99 million per ml in 1973 to 47.1 million per ml in 2011 -- a decline of 52.4% -- among western men unaware of their fertility. For the same group, total sperm count -- the number of sperm in a semen sample -- fell by just under 60%.
No...Blame the food. Whenever I go to those so called 3rd world countries, their fruits taste better, have an aroma and someone can tell that a neighbor is preparing beef or poultry from the perceived smell.
When one visits the fruit section of some of these so called healthy food stores, not an iota of smell/scent of fruit is perceived! Something is surely wrong here.
It is likely the packaging too, look at plastics that leech BPA, which mimics estrogen.
These feminists sound like the worst. I mean, at least the ones that definitely exist and definitely said things that are characterized accurately by what you put in quotes. The articles you linked don't have any feminists saying anything like that, but the post is modded 5 informative so I'm assuming it's good information, and not jumping to conclusions. About feminism.
A combination of obesity in men (besides not being able to spell) and the most highly educated women, those in academia, hating men
When did "women won't have sex with me" turn into "women hate all men".
Most of the women in academia that I know personally are in relationships. Bit of an odd claim that they hate men.
SJW n. One who posts facts.
Citation needed! I can't believe this got +5 Insightful.
Where is the evidence supporting your claim? Has the nutritional value of fruits decreased since the 70s? You could blame anything that has changed since 1973. Why not the lack of lead in gasoline or Internet porn?
Before anyone blames it on any hormone like chemical found in plastics/fertilizers/pesticides/whatever, please show that our exposure has at least increased! For many nasty chemicals our exposure peaked in the 70-80s which increased awareness and regulations during later generations. Our exposure has decreased for many nasties, not increased. Lead being the obvious example but probably many other nasties like plastic softeners etc.
