...women with tubal infertility and 3,833 new mothers, the researchers found that women who had used barrier contraceptives had 40% less risk of tubal infertility. The explanation, suggests one of the report's authors, Harvard Epidemiologist Marlene Goldman, is that these contraceptives prevent any germs carried in the semen from reaching the upper genital tract and causing pelvic inflammatory disease, the most common cause of tubal infertility. Concluded Willard Cates, of the Centers for Disease Control, in an accompanying editorial:"The ulimate educational message is that barrier methods ((ideally used with spermicides)) will not only prevent unplanned pregnancy...
...only known protection against the AIDS virus and other venereal diseases is abstinence or the use of a condom. The AIDS virus can only be transmitted through semen and blood. Because one can never be assured of being free of the smallest lesions in the mouth, anus, or vagina, consistent use of a latex condom is recommended...

...test involves comparing the DNA of blood, semen or hair roots found at the scene with the DNA of a suspect. What makes it virtually foolproof is that no two people (other than identical twins) have the same genetic characteristics. While considering this fact in 1983, Alec Jeffreys, a geneticist at the University of Leicester in England, realized it might be the basis for an important new tool in criminal investigations. Using restriction enzymes as "scissors," he cut the DNA taken from several people into segments and arranged them into patterns that somewhat resemble the bar codes found on supermarket...
