We always associate infertility with biological factors, but that is not true. There are a number of other reasons that play a role in the low fertility rates among individuals.
Scientists reveal that a global decline in fertility has a number of causes, but increasing biological infertility or infertility is not one of them.
A new study finds that toxins and climate damage are likely to blame for reduced fertility.
Recent reports of an article by Shanna Swan, the author of Spermageddon, and others have claimed that the article shows that exposure to pollutants has lowered 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 took into account regional differences, found that sperm counts in the US have increased in recent years.
Although there are other mechanisms by which biological fertility can be affected, time to pregnancy TTP directly tracks how quickly couples become pregnant.
TTP rose in Britain in the late 20th century and has remained stable in the US between 2002 and 2017 for women under 30, only increasing by about 4% for women who already had a child.
Meanwhile, infertility in developed countries has remained about the same or decreased in recent years.
This suggests that trends in pollution-related damage to fertility, if any, are not responsible for the recent decline in fertility rates.
Explanations for recent trends would be better off looking at the turning point; In much of the Western world, fertility rates peaked around 2007-2010 and have fallen since.
We would therefore be better off examining economic conditions and smartphone use and their effects on the link as likely causes of the fertility decline.
Notably, the study was unveiled by Peter Foreshaw Brookes, director of The Center for Family and Education.
