...Naeye speculates that sperm or enzymes in the seminal fluid may somehow aid bacteria in penetrating the cervix and entering the uterus. But both Naeye and obstetricians are cautious about any wholesale proscriptions of sexual activity during pregnancy. They point out that the births studied took place between 1959 and 1966, when the fetal and infant death rate was much higher than now. Thus improved methods of caring for expectant mothers and newborn infants may have obviated some of the harm that could result from sex during pregnancy. Also, the analysis did not take into account the effect of intercourse...
...much as $20,000, are injected with a hormone that causes multiple ovulation, the production of more than one egg. The eggs are then fertilized by artificial insemination and, about a week later, the live embryos-usually five, but sometimes ten or more-are withdrawn through the cervix by means of a catheter. Each embryo is then transferred, either by a six-inch incision in the side or directly through the cervix, to the uterus of a less perfect host mother, which carries the superior calf to full term. Since supercows, or "queen bees," can be bred seven times...
...during menstruation and for seven days thereafter, Epidemiologist Susan Harlap reports a surprising result in the New England Journal of Medicine: of the 145 babies born to women who resumed intercourse two days after ovulation, 65.5% were boys; normally the figure is about 50%. One theory: the vagina and cervix at that time of month are more hospitable to sperm containing male chromosomes...
...test is familiar to almost every woman who has visited a gynecologist. To take a Pap smear, the doctor inserts a metal device that enables him or her to see into the vaginal tract. Then he inserts a swab or spatula, scrapes some cells from the cervix and smears them on a glass slide, which is then sent to a laboratory for microscopic examination. A few days later, the doctor receives a report indicating whether the cells are normal, atypical or malignant. The patient gets a bill for about...
...point out that the incidence of invasive cervical cancer has fallen by more than 50% since yearly screening became widespread, they have no hard evidence to link the drop to the test. The decrease might be explained by other factors like the increasing number of hysterectomies, in which the cervix is usually removed. The true efficacy of the test is also clouded by the fact that though half the adult women in the U.S. have Pap smears annually, relatively few of the tests are on women who run the highest risk of developing cervical cancer. The disease is most prevalent...
