...deprive persons of life without due process of law, human life shall be deemed to exist from conception." The intent is clear. Explains Hyde: "If the fetus is human life, as of course it is, it ought to be accorded equal dignity with the snail darter and the sperm whale." The effect of the bill, theoretically, would be to allow the states to pass laws defining abortion as murder...
...Normally sperm are conveyed toward the outside of the body through ducts, the vasa deferentia. In a vasectomy, the ducts are cut, but sperm continue to be manufactured. With the exit passage blocked, the sperm break down and leak into surrounding tissue and possibly into the bloodstream, where they are recognized as "foreign" and attacked by antibodies. Alexander and Clarkson postulate that the resultant sperm-antibody complexes injure the artery walls and accelerate formation of atherosclerotic plaques...
...procedure can be used when a woman's fallopian tubes are blocked. Doctors remove an egg from the prospective mother, fertilize it with her husband's sperm outside the body, and then emplant the embryo in the woman's womb. Biggers said no more than four babies have been conceived and born using the method...
Like the diaphragm, the cap works by preventing sperm from migrating from the vagina to the uterus and then to the fallopian tubes, where conception occurs. The diaphragm is a thin rubber shield held in place against the vaginal wall by the tension of its springy rim. The cap is a thicker, thimble-shaped rubber or plastic cup that fits snugly around the neck of the uterus, the cervix, and is kept in place by suction. Both devices are used with spermicidal cream or jelly...
...researchers drew out the egg and sperm nuclei that were already in the black mouse's egg so that their genetic information could not influence the resulting clone. Next they cultured the cell in a solution of nutrients until it divided and grew into an early embryo, which was then inserted into the womb of a third mouse, this one white. The white mouse gave birth to a gray mouse, genetically identical to the original embryo...
