...which showed that weekly injections of the hormone effectively prevented conception by decreasing sperm counts. Administered over two and a half years, the injections proved to be effective means of contraception for 98.6 percent of the couples involved, with only four pregnancies reported. "It would show that testosterone, like estrogen in a female, can be an additional method of reproduction control," said Richard Sherins, the director of andrology at the Genetics and IVF Institute in Fairfax, Virgina. "Testosterone may be a new way of looking at birth control," says TIME's Alice Park. "If it is true, it would...

What scientists do know is that water, air and soil all over the world are tainted with small amounts of many of these chemicals. They know that once the pollutants get inside the body, they can bind with receptors that normally recognize estrogen and other natural hormones. They know that these hormones are crucial to the development of a normal reproductive system. And they know that--in lab tests on animals, at least--vanishingly small amounts of industrial chemicals, delivered at just the crucial stage of fetal development, can "feminize" a male embryo, producing smaller testicles, low sperm output...
