As someone who has had to do IVF for our child and go through the challenge of figuring our what to do to try and improve sperm quality, I can tell you once you start looking into it, basically everything about modern life is bad for sperm. Heat, radiation, plastic, micro plastics, soya, tap water, Teflon, antibacterial soap, underpants, western diet. It’s a perfect storm. If you’re going though it though I offer a r…

Weight loss and proper exercise will probably deliver 99% of the improvements for 99% of the people. Stressing about heat, radiation, micro plastics, or other random stuff seems like extra stress for not that much benefit. Most people in Western world are either out of shape, or straight up obese. It makes sense that, that will have huge negative effects on fertility.

Is it possible that endocrine disruption could be related to issues with physical fitness too? There are many factors, but this could also be one, perhaps.

While I tend to agree with you WRT to diet and exercise, I think this is a secondary issue to what's being described here, similar to how I think modern science and technology has skewed the natural selection process with a bias that may select for undesirable attributes. Some of this bias may be for good intentions (allowing less fertile couples to conceive) while some may have questionable outcomes (selection based purely on socioeconomic status). Again, I think these are separate issues. Efforts I worked with looked at effects of contaminants such as manganese artificially introduced in natural water systems but that's just one, there's dozens of concern.

The issue discussed in this article has quite a few biologists I've interacted with concerned which deal with products we redistribute or manufacturer back into the environment that may be causing these issues. Endocrine disruption is occurring in other species in the wild less or not clearly effected by the issues described above (selection bias, cultural biases in exercise/diet, etc.), and for all intents and purposes, seem to be going along with a sort of survival of the fittest model yet they're still having endocrine issues.

In the anthropocene era, it's quite possible some of our behaviors are causing this and it wouldn't be the first time: lead and CFCs come to mind in the past. We have what appears to be a smoking gun, but we still haven't identified the shooter. We should definitely improve the factors that we can like diet and exercise and look to remedy socioeconomic selection biases for reproduction but the issue at hand may be one you can't simply diet and exercise your way out of and we need to continue to investigate it and find the root cause.

You... avoided all that? How? You didn't wear underpants or what?

I'm not the parent poster, but here's my take: Heat - Live somewhere North. There's very little of it. Radiation - No wi-fi at home, put phone in breast pocket. Plastic, micro plastics - Never buy anything plastic, if possible. Buy food whole in paper bags from local market; prefer glass and carboard containers. Buy cotton/silk/etc clothing, never anything made of poly-anything. Tap water - Live where it's clean. Tef…

> Radiation - No wi-fi at home, put phone in breast pocket.

This is pseudoscience. Unless you're storing wifi devices next to your testicles they won't do anything, and in that case it's due to heating.

Can these endocrine disruptors also contribute to gender dysphoria?

Given that there isn't a dramatic increase of homosexual population, its probably not a major cause. In fact IIRC homosexual men with high T tend to be "more exclusively homosexual".

It doesn't help that most research on the subject seems to be from the 70s, and i don't find many recent studies. ( I guess, because contemporary science)

Like I said, I was going for the nuclear option and biscuits have sugar in. Sugar makes you fat. Fat belly means less testosterone. This is part of the anti-western diet thing.

> Sugar makes you fat. Nonsense. Overeating makes you fat, not a specific carb. Having a biscuit with a few grams of sugar is not going to impact your health in a meaningful way if you're not overeating.

One biscuit no, but perhaps it was easier for him to always say no instead of occasionally saying yes, which could easily turn into saying yes too often.

It’s called the globohomo agenda and they want to make you weak so you can’t fight back.

No, the globohomo agenda is turning all the cute young men gay. Not you, from your words I can tell you're ugly.

> Store food in glass containers, not plastic. Above all, don’t microwave foods in plastic or with plastic wrap on top. Avoid pesticides. Buy organic produce if possible. Avoid tobacco or marijuana. Use a cotton or linen shower curtain, not one made of vinyl. Don’t use air fresheners. Prevent dust buildup. Vet consumer products you use with an online guide like that of the Environmental Working Group. I really want t…

It's difficult to do it all at once. Taking little steps might help: instead of using plastic tupperware, use glass; instead of buying beans in a can, buy dry beans; balcony garden? Sure!

Even if some things are impossible to do, it's imo best to not pile on top of those problems issues that aren't impossible to solve.

I'm not sure you should specifically be worried about vinyl shower curtains, but vinyl is a specific concern, because to get the form of vinyl that's soft and pliable, the vinyl is mixed about 50/50 with phthalates that are known endocrine disruptors. That said, phthalates are used in tons of stuff, and it's not fully clear to me which sources are the most important. I've replaced my soap/shampoo/shaving creams with…

> I've replaced my soap/shampoo/shaving creams with phthalate free versions How do you identify these? You mean there are products that advertise themselves to be phtalate free? Or that you are actively looking for phtalate composition in the products you buy?

They’ll advertise it clearly on the bottle.
