Such "reproduction expediting" includes one-night stands and adventurous bedroom behavior, the research shows.
In a paper published in the July edition of Personality and Individual Differences, psychology graduate students Judith Easton, Jaime Confer and Cari Goetz, and David Buss, professor of psychology, found that women age 27-45 have a heightened sex drive in response to their dwindling fertility.
In the study the researchers split 827 women into three groups: high fertility (ages18-26), low fertility (ages 27-45), and menopausal (ages 46 and up). The respondents answered an online questionnaire about their sexual attitudes and behavior.
Compared with the other groups, women with low fertility were more likely to experience:- Frequent sexual fantasies
According to a 2010 report from the Pew Research Center's Social & Demographic Trends, mothers of newborns in all race and ethnic groups are now older than their counterparts 20 years ago. Fourteen percent of births in 2008 were to women ages 35 and older, and 10 percent were to teens. With more women having children past their peak childbearing years, Easton says she believes the research will have implications on reproductive and sexual health issues, such as fertility, sexual dysfunction and marital development.
"Our findings suggest that women don't need to necessarily go 'baby crazy' in their 30s or go around thinking they're supposed to be having a 'sexual peak,'" Easton said. "Our results suggest there is nothing special about the 30s, but that instead these behaviors manifest in all women with declining fertility. It may be more difficult to conceive past the age of 35, but our research suggests women's psychology will continue to motivate them to try until menopause."
The study outlines for the first time the changes in women's reproductive behavior across the life cycle from an evolutionary standpoint. The researchers attribute these differences to ingrained psychological mechanisms rooted in each gender's adaptive responses over millennia of human evolution.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
