We always associate infertility with biological factors, but this is not true. There are many other reasons also involved in low fertility rates among individuals.
Scientists have revealed that there are many reasons for the global decline in fertility, but increasing biological infertility or infertility is not one of them.
A new study has shown that the decline in fertility may be caused by toxins and climate loss.
A recent report of a paper by Shanna Swann, author of Spermageddon, and others claims that the paper shows that exposure to pollutants is reducing biological fertility and may have contributed to the decline in fertility rates in recent years, which is unlikely to be believed.
A meta-analysis published last year, which controlled for regional variation, found that sperm counts have increased in the US in recent years.
Although there are other mechanisms by which biological fertility may be affected, timing of pregnancy TTP directly tracks how quickly couples conceive.
TTP increased in Britain in the late 20th century and has remained stable for women under 30 in the US between 2002 and 2017, increasing only by about 4% for women who have already had a child.
Meanwhile, infertility has remained the same or has been declining in developed countries in recent years.
This suggests that trends in fertility loss from pollution, if present, are not responsible for the recent decline in fertility rates.
It would be better to look for an explanation of recent trends at a turning point; In much of the Western world, fertility rates peaked around 2007–10 and have been declining since then.
So it would be better if we examine economic conditions and smartphone use and its effects on coupling as possible reasons for fertility decline.
