Lifestyle, Climate, and Toxic Foods to blame!
Another meta-analysis in 2022, again led by Hagai Levine, reports that sperm concentration declined by 53.3 percent and sperm count by 56.3 percent in Western (Predominantly European) countries (1973-2015), and by 27.6 and 24.7 percent respectively, in non-Western (Melanated) countries (1986-2018).These two papers found increasing percentage decreases in sperm concentration—most notably in Western countries—since the 1970s. Levine says that he wouldn't expect small differences in counting methods between studies to account for the significant overall decline observed on average.Racial differences were seen where Asians had the highest mean semen concentrations (69.2 × 106/mL) while blacks had the lowest (51.3 × 106/mL).The major difference being black sperm were the healthiest of all races and more likely to conceive in general, if you have a higher number of normal-shaped sperm, it means you have higher fertility.
But infertility doesn't only affect men, in the United States, among married women aged 15 to 49 years with no prior births, about 1 in 5 (19%) are unable to get pregnant after one year of trying (infertility).In addition, White American women (29.5%) had a significantly higher frequency of unexplained infertility compared with Black and Afro Hispanic women (10.3%). For infertility treatment, the proportions of patients by ethnicity in 2020 were: White (92%), followed by Asian (3%), Black (2%), Mixed (2%) and Other (1%).
Women of Middle America the so-called Bible belt are becoming less and less interested in having children. Women in the U.S. and much of the Western world have been experiencing a drop in fertility rates in the 21st century. Nowhere is this more apparent than in Colorado, where the trend has been especially pronounced. It has one of the nation’s lowest fertility rates and saw one of the sharpest declines in birth rates over the last 20 years.
The fertility rate differs from the birth rate. While the birth rate measures the number of children born for every thousand people, the fertility rate measures how many children are likely to be born per woman in childbearing years. Demographers estimate fertility rates need to be around 2.1 in order for a country to continue growing in population. Like all of Europe, U.S. fertility rates are below replacement level. At 1.48, Colorado’s fertility rate was the sixth-lowest in the U.S. in 2020, the most recent year tracked by national vital statistics.
Colorado’s total fertility rate is 1.48, lower than the national rate of 1.64 and well below the replacement level. Only Maine, Massachusetts, New Hampshire, Oregon, Rhode Island and Vermont have lower fertility rates. The U.S. fertility rate hit a record low in 2020 — just as it did in 2019, and 2018. In the past low fertility rates broadly tracked with high income and education levels. The states with the lowest rates concentrated along the West Coast, New England and the Southwest. Now it is across the board with the exception of Black and Latino numbers which are on a steady rise. U.S. birthrates are down sharply from 15 years ago, as women report that economic and social obstacles are causing them to have fewer children than they want. The number of babies born in the U.S. started plummeting 15 years ago and hasn't recovered since.
Not one state has a replacement-level fertility rate. Even the highest – the Dakotas, Louisiana, Utah, Georgia and Texas – come short of 2 children per woman. This trend has been years in the making. Every state in the U.S. has a lower fertility rate now than 10 years ago. Colorado had one of the sharpest downswings.
Colorado’s fertility rate plummeted by 23% from 2010 to 2020. Only Arizona had a bigger drop in fertility. Surrounding states have seen the same trend develop, some U.S. regions have seen fertility drop much faster than others. Western states – those that touch the Rocky Mountains and further west – have seen fertility rates decline by almost twice as much as the rest of the U.S.
