Rick Noack, The Washington Post Published 6:16 am PST, Friday, November 9, 2018 Almost half of all countries have fertility rates below the replacement level, according to an unprecedented study published by The Lancet journal. While there was not a single nation with a fertility rate below the 2.05 threshold back in 1950, the global average is now only 2.4 - down from 4.7 about 70 years ago. Differences between nations have become more pronounced, with some European countries having record-low rates down to one child per woman on average, compared to more than six children in some African nations. If you live in a poorer nation with high fertility rates, a decrease would likely be a reason for celebration. Lower fertility rates are often the result of fewer child deaths, easily accessible contraception and prosperous economies, which explains why Europe, North America and richer Asian nations like Japan are disproportionately affected. In countries with … [Read more...] about Fertility rates around the world are declining. Trump supporters won’t like the solution.
(The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.) Caroline Sten Hartnett, University of South Carolina (THE CONVERSATION) The Centers for Disease Control reported this month that the number of births in the U.S. is down 2 percent – “the lowest number in 30 years.” These reports were met with surprise and alarm. ScienceAlert, for example, led with the headline “U.S. Fertility Rates Have Plummeted Into Uncharted Territory, and Nobody Knows Why.” However, this recent decline fits with global trends and isn’t unprecedented in U.S. history. As a demographer who studies fertility trends, what strikes me as anomalous is not the recent drop, but the previous high fertility “bubble.” The U.S. maintained surprisingly high fertility rates for a long time. After the baby boom of the 1950s and 1960s, fertility in the U.S. and other wealthy countries fell during the 1970s. However, the … [Read more...] about US fertility is dropping. Here’s why some experts saw it coming
A new study says that new and expecting mothers in Flint, Michigan faced tragic circumstances during the water crisis. Research by assistant professors and health economists David Slusky at the University of Kansas and Daniel Grossman at West Virginia University says that during the period after April 2014, fertility rates dropped among local women by 12 percent and fetal death rates jumped by 58 percent, according to the Detroit Free Press. They compared the stats with 15 other Michigan cities, including Detroit.“We weren’t particularly surprised by this, but we didn’t expect it be as clean and clear as it was,” Slusky said according to the outlet. He explained that other cities’ fertility rates stayed consistent, but Flint’s “fell off a cliff.” Researchers tried to account for other possible explanations, including concerns about the economic recession starting in 2008, which is why they looked at other cities’ … [Read more...] about Fertility ‘Fell off the Cliff’ During Flint Water Crisis, Researcher Says
You may want the greenest lawn possible, but a proposed Pennsylvania law may limit how much grass fertilizer you can use in trying to achieve it.The bill passed the state Senate 47-3 in March, and is now in the state House.If passed into law, the bill would dictate how much fertilizer can be applied to lawns, golf courses, parks, schools, colleges, playgrounds and athletic fields.Applications for agriculture — which faces separate restrictions on runoff of fertilizer — are exempt.The goal is to cut back on nutrients running off of turf grass into local streams and the Chesapeake Bay, where it promotes the growth of algae that uses up oxygen needed by aquatic life.The legislation is a modified version of a bill first proposed by former state Sen. Michael Brubaker of Warwick Township in 2014.Expanded since Brubaker’s effort died in the General Assembly, the fertilizer bill is more aimed at lawn-care services and manufacturers of all types of commercial fertilizer, not … [Read more...] about Pennsylvania bill would place limits on fertilizer placed on lawns, golf courses, schools

New research suggests that a man’s age can affect his chances of successfully fertilizing an egg via IVF, and that women with older male partners have a lower chance of conceiving a child.New research has revealed that the success of IVF weighs heavily on both the age of the mother and the father. The report found that a 35-year-old woman has more success conceiving with a man under 30 than she does with a man her same age, The BBC reported. Although this news is enlightening, the report concluded that the age of the woman was still far more important … [Read more...] about IVF Pregnancy: Why A Man’s Age Is Also Important For In Vitro Fertilization Success
