Correlation, or causation?

What explains the 60% drop in sperm count in just 40 years?

I am almost 100% sure this "infographic" is absolute garbage. Which studies is this based on?

And even if the numbers are true:
- since then the Concorde has been in use
- Grateful Dead has been around
- Mortgage bonds were used
These could be true just as much

This but also IF sperm counts are dropping I would look at birth control meds and plastic in water supplies as the main culprits, but who knows. there is not enough evidence as of yet to determine a cause and researching this would only hurt invested interests of the majority of people funding "Scientific™ "Study"" so it will never get done and if an independent researcher finds anything and tries to publish his works he will be mocked and shunned

why are things so awful in the world again? remind me.

There are only two data points for the sperm count?
This graph is useless.

I think they got the mean sperm count among x participants in 1970, and again among y participants in 2010.

Would be funny if they did, but I guess not. Otherwise it's really completely useless.

i really don't understand how the very small concentration of leeching monomers can do all this? DDT, PCB and literally thousands of disrupting pesticides had much more pronounced estrogenic effect and were banned between the late 70s to early 2000s, why are people that were exposed to those in insane qualities more fertile?
>inb4 onions
phytoestrogens are suggested to not be a carbon copy of estrogens and actually have a different pathway and some of them literally block estrogen

plastics ain't great, but i imagine the decrease has more to do with lifestyle changes in the modern world. On average we're more sedentary, getting less sleep, and have a higher than in the past.
Micro plastics are probably working in conjunction with those factors to tank sperm

Do do the rapid increase in available pornography through the internet?

Oooh, or do the fact that masturbation has gone from a serious transgression of high morality to an acceptable and almost celebrated pastime since the availability of said pornography since the 60's.

How about the increase in sugar?
Or the free-radicals in air pollution?
