That article is not saying sperm counts are not dropping, but arguing that that is not linked with dropping fertility (and that the original study is racist for only including western countries or something).

Not a biologist, but that kinda makes sense: you only need one single healthy sperm to reach the egg in order to fertilize it, so even men with pretty bad sperm counts are probably still able to have children. So the average sperm quality may drop for some time without a corresponding drop in fertility. But then the drop in fertility will be all the worse...

Great news for people like me who don't want to reproduce.

Do you intend to become elderly? Perhaps not so great news in 50 years when you are looking for a nursing home.

a child is a ridiculously expensive, time consuming, and undependable insurance policy

I read both links. This one sounds like a bunch of woke people unhappy that mens health is getting attention. The other study sounds legitimate.

It’s going to be a real adjustment for a lot of these people to grasp that young American men are in really difficult situations socially, academically, and that it’s a key factor to underemployment, violence, etc… the concept of men’s health or men suffering feels like an attack to these people instead of a separate legitimate issue to other social topics they find important

A study not written by a scientist to oppose scientists. Allowing literature/philosophy people to publish on everything is as bad as allowing antivaxxers everywhere.

Earlier quoted context omitted.

Less soy?

No, you'd need to be chugging multiple jugs of soy milk a day for that to (maybe) matter. Better would be to lift, eat better, sleep, etc.

You’ll be surprised. Some vegan friendly foods which are delicious are packed with more than 1x your daily value in a single serving. So if you eat two a day for instance the levels of estrogen you’re pumping in are quite significant and very very easy to do.

I had a test recently and I have 0% "normal" sperms, when 4%-14% is the normal range. Pretty radical. The doctor said to take vitamins, to get testosterone to normal level, and to excercise. In other words not much to do

Your sperm does reset ever 75 days. Depending on the problem, it may be fixable. Exercise and raising testosterone will have a meaningful effect. Also check the various products you are using for endocrine disruptors and also you can go organic in terms of food (avoids pesticides, which are suspected of playing a role.)

Organic foods still use pesticides, sometimes even chemically identical ones to non organic, just sourced via allowed methods.

The lack of federally funded research on this topic is astounding. It's been like this for a long time, but ignored. Even more notably has been the lack of curiosity from the media and academia. They simply shrug and move on, as if the root cause of this isn't something we should look into as potentially causing other problems that are even worse. Edit: The downvotes without any comment refuting this highlight the is…

Its the same with obesity, which has been sharply increasing in much of the world since the 1970s, but pretty much all the conventional explanations (increased availability, excess sugar, excess carbs, excess fat, decreased physical activity, etc.) don't seem to stand up to scrutiny.

Hypothesis: the cause in both cases is likely industrial contaminants considered essential to the running of modern civilization, so nobody wants to, or is encouraged not to, look too hard.

Isn't this contradicting? What were your test/free-test levels?
