...issue of sexual harassment ricochets off other crucial debates this country has yet to resolve about the boundaries of morality and law. The boss who kept his employees' menstrual cycles marked on a wall calendar was, by any measure, a lout. Was he a criminal? How useful is it to establish a category of behavior that runs the gamut from rudeness to rape? Should it be embedded in the law that men and women react differently to the same comments and behavior...
...method does have drawbacks. Progestin causes irregular menstrual bleeding in 75% of women who use it. Women may get their periods at odd intervals, such as 3 or 7 weeks apart, and some could miss one altogether. The periods themselves can also be longer, an average of 8 days of bleeding or spotting as opposed to the normal 5 days. These effects diminish after the first two years, according to the manufacturers. In addition, the cost, although less than that of oral contraceptives, will be considerable. Wyeth- Ayerst officials will not reveal the price until marketing begins in February...
...study, however, the researchers were not examining older women. Instead, they were trying to find out why one group of young women -- marathon runners -- seemed to be peculiarly predisposed to osteoporosis. The researchers theorized that disruptions in the runners' menstrual cycles might be at fault. But to their surprise, when they compared the marathoners with women who ran for recreation and others who engaged in no special physical activity, the researchers found that menstrual disturbances were common in all three groups...
...fact, almost 30% of all cycles experienced by the 66 women over a 12- month span were in some way disrupted. The upset was caused either by a failure to ovulate (or produce an egg) or by a shortened "luteal phase," a critical stage of the menstrual cycle during which the hormone progesterone is produced. More important the researchers found that these disturbances were directly related to dramatic bone loss: the 20% who missed ovulation at least once, for example, suffered as much as a 4% reduction in bone density in one year...
...might menstrual problems hurt bones? Lead researcher Jerilynn Prior believes that reduced levels of the hormone progesterone -- which was suppressed in women with cycle disruptions -- may explain the damage. Some studies have indicated that this hormone helps with bone formation. Prior is not certain what causes the menstrual disturbances. The most likely candidate, she says, is stress...
