Stuff briefs: Sex and pregnancy myths; Wendy's goes digital

the only story today that you need to read before having sex

What's the best time to conceive? Many women do not know the answer, according to a study by the Yale School of Medicine published in the journal Fertility & Sterility. Only one in 10 women surveyed were aware that intercourse needed to occur before ovulation, rather than after, to optimize conception; half of the respondents believed that having sex more than once per day would increase their chances of conception (sperm count decreases after intercourse, so sex more than every other day is actually counterproductive); and one-third believed that specific sexual positions would similarly increase their success with achieving pregnancy. The study also found that 40 percent of women in the survey believed that their ovaries continue to produce new eggs during reproductive years. "This misperception is of particular concern, especially so in a society where women are increasingly delaying pregnancy," noted Lubna Pal, associate professor in the section of Reproductive Endocrinology and Infertility at Yale.

Who'd believe this?

Is there really a link between vaccine and autism, or cellphones and cancer? A surprising number of Americans believe the answer is yes. Two University of Chicago social scientists set out to determine the extent of "medical conspiracism" and conducted a nationally representative online survey. Among the results, published online by the journal JAMA Internal Medicine:

37 percent endorsed the belief that the Food and Drug Administration, under pressure from pharmaceutical companies, is suppressing natural cures for cancer and other diseases.

20 percent said they believed that cellphones had been found to cause cancer but that the government had bowed to large corporations and would do nothing to address the health hazard.

One in five said they agreed that physicians and the government "still want to vaccinate children even though they know these vaccines cause autism and other psychological disorders."

Wendy's accepts digital payment

Wendy's is rolling out a program that lets customers pay using their smartphones at most of its 5,800 U.S. locations. The move reflects a push by fast-food chains to court younger customers. "We want to allow them to pay the way they want to pay," said Craig Bahner, chief marketing officer for Wendy's. To pay with the Wendy's app, customers tap the app to pull up a six-digit number they tell the cashier, rather than holding up their device to a scanner. "That's a real benefit when you think about cars going through pickup windows," Bahner said. The app doesn't yet offer discounts or a loyalty program, a feature that's considered a way to help cultivate customer loyalty. Burger King said last week it would introduce a mobile payment program in April. — tbt* news services
