Ovulation May Result

In More Frequent Sex

Women are likely to have more sex on the days when they are most fertile, even if they are not trying to get pregnant, scientists said.

"There apparently are biological factors promoting intercourse during a woman's six fertile days, whether she wants a baby or not," said Allen Wilcox of the National Institute of Environmental Health Sciences in Durham, N.C. He and his colleagues, reporting today in the journal Human Reproduction, do not understand the reasons.

In a study of 68 women who recorded when they had sex over a three-month period, Wilcox and his colleagues discovered that during ovulation, when a woman is most likely to become pregnant, the overall frequency of sex increased by 24 percent.

Stopping Nausea After

Surgery Can Be Cheap

The first head-to-head comparison of common treatments for preventing nausea and vomiting after surgery found that drugs costing a dollar or two work just as well as a more expensive medicine.

Also, a combination of two or three drugs was found to be more effective than just one at preventing vomiting after an operation.

The study appears in today's New England Journal of Medicine.

Nausea and vomiting are common side effects of gas anesthesia and opium-related painkillers. Post-operative nausea affects one out of three surgery patients -- about 25 million a year in the United States.

The study was led by Christian C. Apfel, who began the research at the University of Wuerzburg in Germany and now also works at the University of Louisville. He studied 64 possible combinations of six nausea treatments.

Antidepressant Use in

Pregnancy Draws Alert

Drugmakers are adding a notice to widely used antidepressants that babies of women who take the drugs late in pregnancy may experience jitteriness and other withdrawal symptoms, U.S. officials said yesterday.

The Food and Drug Administration urged the precaution in light of scores of reports of withdrawal effects in newborns of women who took certain antidepressants during the third trimester of pregnancy, agency officials said.

The new information on drug labels urges physicians to carefully weigh benefits and risks of antidepressant therapy in women during the late stages of pregnancy, said Robert Levin, in the FDA's division of neuropharmacological drug products.

Untreated depression poses serious risks for mother and baby, too, so doctors should not automatically avoid giving the drugs during pregnancy, officials emphasized.
