...mother's womb. The process is distressingly hit-or-miss, though, and the odds of a successful pregnancy go up with the number of embryos used. In a typical in-vitro procedure, doctors will insert three to five embryos in hopes that, at most, one or two will implant...
...many to be the real strongman, has budged. Now the U.S. must decide how far it is willing to go to see Aristide back in power. If the U.S. has interests there, they are not ones that Americans can easily grasp. There may be a moral desire to implant democracy in Haiti, though its bloody history and repressive regimes seem inimical to that form of government. Wanting to help without getting stuck, the Clinton Administration has relied on diplomacy -- but its impact is weak without a credible threat of force...
...fertilized embryos they had frozen and stored in a Tennessee clinic, the Davises wound up in the Supreme Court. Junior Davis had requested that the embryos be destroyed, asserting his own "reproductive rights." His ex-wife claimed a right to her "offspring." In refusing Mary Sue Davis' appeal to implant the embryos in her womb, the court decided that Junior Davis' right not to become a parent outweighed his ex-wife's claim. The Justices upheld a lower court's ruling that in such cases "procreational autonomy" gives men as well as women an overriding right not to become parents...
Biomimetic materials hold particular promise as coatings and wrappings that increase the body's tolerance of implanted devices. Eventually these substances may be put to work as nearly natural replacements for injured ligaments and arteries. University of Alabama molecular biophysicist Dan Urry, for example, has succeeded in turning a key segment of the protein elastin, present in many body tissues, into a material whose expansive and contractile properties closely approximate those of arterial walls. The material can be fashioned into tubes that feel, uncannily, like real blood vessels and also into sheets for encasing mechanical devices like pacemakers. Tests...
Norplant consists of six matchstick-sized capsules that, when inserted under the skin of a woman's arm between her armpit and her elbow, begin releasing small amounts of progestin, a hormone that blocks ovulation. The implant is effective within 24 hours of insertion for a period of five years with a success rate of 99.8%. Norplant is also cheap at about $500 for the capsules, insertion, and removal. By comparison, purchasing birth control pills over the same period would cost $900. Once Norplant is removed, fertility is restored. Not even stitches are necessary...
