A more recent paper by Levine et al., published in November 2022, confirmed these conclusions and expanded them to include Africa and South America. Among men from all continents, the authors concluded, “the mean [sperm count] declined by 51.6% between 1973 and 2018.” The study also found that the decline rate, currently about 2 percent per year, is increasing. The trend, if extrapolated, would result in near-universal male sterility by about 2060.
Recent research shows that whole classes of these chemicals are affecting sexuality and disrupting reproduction—not just in humans, but in a host of other animal species as well. But the whole subject is controversial and is getting far too little attention, partly because reproduction and sexuality are culturally sensitive topics, and partly because the chemicals industry wields considerable political power.
It Gets Worse
Perhaps the most frightening biological impact of many endocrine-disrupting chemicals is their tendency to alter DNA expression in ways that can be inherited by subsequent generations. It’s long been known that environmental factors (food, air, water) can cause genes to be switched off or on, or dial their expression up or down. Sometimes the effects are transgenerational, and continued presence of chemicals in the environment can amplify biological impacts from one generation to the next.
Anthropogenic contaminants in water can impose risks to reproductive health. Most of these compounds are known to be endocrine disrupting chemicals (EDCs). EDCs can impact the endocrine system and subsequently impair the development and fertility of non-human animals and humans. The source of chemical contamination in water is diverse, originating from byproducts formed during water disinfection processes, release from industry and livestock activity, or therapeutic drugs released into sewage. This review discusses the occurrence of EDCs in water such as disinfection byproducts, fluorinated compounds, bisphenol A, phthalates, pesticides, and estrogens, and it outlines their adverse reproductive effects in non-human animals and humans.

The study didn’t suggest any causes for the decline, but many experts point to the pesticides and environmental pollutants found in industrialized nations as a possible culprit, since toxic elements have been proven to impact sperm counts. Other possible causes include rising obesity and stress.

Terrified that trans-folk are going to take over your daughter's bathroom or move in next door, think on this from the same article:
Keep pumping those kids full of hormones; that should do the trick.

technically, who cares.
if people cannot reproduce, that does not mean anyone will dye.
they will just 'run out'
another species will pop up in 20k years.
maybe they will not have any usuristz, and that species can have peaace!

This is interesting to consider what if forever chemicals in the environment is a great filter event exterminating intelligent species when they always feared it would be nuclear war and fallout. Short sighted people created the forever chemicals and it never gets the attention it deserves until it’s too late. Game over within decades. Hopefully it’s not game over for humans. I have hope. Africa and other places are still expanding their populations. Environmental forever chemicals are dangerous. The chemicals are in all of us and in animals and accumulating unfortunately from what I’ve heard. Unfortunately I’ve heard talk that since the chemicals are considered more of a male issue instead of a survival of the human race issue, the issue doesn’t get much attention.
In the future, pollution has rendered humans unable to reproduce. Teams are sent into the past to abduct people who are about to die; the plane crashes were part of this plan. The abductees are kept in stasis until they can be sent into the far future to repopulate the Earth. Most of the current population is in poor health but the time travelers—mostly women—are relatively healthy and are given the best food and care to pass for 20th-century humans. Present-day air is too clean for the time travelers to process; they smoke cigarettes to mimic their own timeline's atmosphere.
