Oysters may excite the libido, but there is nothing like a hearty breakfast laced with sugar to boost a woman's chances of conceiving a son, according to a study released Wednesday. Likewise, a low-energy diet that skimps on calories, minerals and nutrients is more likely to yield a female of the human species, says the study, published in Proceedings of the Royal Society B: Biological Sciences, Britain's de facto academy of sciences. Fiona Mathews of the University of Exeter in Britain and colleagues wanted to find out if a woman's diet has an impact on the sex of her offspring. So they asked 740 first-time mothers who did not know if their unborn foetuses were male or female to provide detailed records of eating habits before and after they became pregnant. The women were split into three groups according to the number calories they consumed per day around the time of conception. Fifty-six percent of the women in the group with the highest energy intake had sons, compared to 45 ...

Sex takes 3 to 13 minutes, study says Story Highlights Survey of sex therapists seeks optimal amount of time for intercourse Time doesn't count foreplay; 1 to 2 minutes rated too short 2005 study found median time for sexual intercourse was 7.3 minutes Researcher hopes to ease minds of those who think they "should last forever" NEW YORK (AP) -- Maybe men had it right all along: It doesn't take long to satisfy a woman in bed.

The findings, to be published in the May issue of the Journal of Sexual Medicine, strike at the notion that endurance is the key to a great sex life. If that sounds like good news to you, don't cheer too loudly. The time does not count foreplay, and the therapists did rate sexual intercourse that lasts from 1 to 2 minutes as "too short." Researcher Eric Corty said he hoped to ease the minds of those who believe ...

A new, highly drug-resistant strain of the “flesh-eating” MRSA bacteria is being spread among gay men in San Francisco and Boston, researchers reported on Monday. In a study published online by the journal Annals of Internal Medicine, the bacteria seemed to be spread most easily through anal intercourse but also through casual skin-to-skin contact and touching contaminated surfaces. The authors warned that unless microbiology laboratories were able to identify the strain and doctors prescribed the proper antibiotic therapy, the infection could soon spread among other groups and become a wider threat. The new strain seems to have “spread rapidly” in gay populations in San Francisco and Boston, the researchers wrote, and “has the potential for rapid, nationwide dissemination” among gay men. The study was based on a review of medical records from outpatient clinics in San Francisco and Boston and nine medical centers in San Francisco. The Castro district in San ...
