We left the slippery slope of private human research and are in free fall. If nothing is done soon, Congress will face problems in which the worth of humans is measured as property value. Consider the progression of events. Compassionate and skillful in-vitro fertilization for infertile couples under a physician's supervision is common.
Human eggs are in great demand and are a commodity just like soy beans and computer chips.
University women have been selling their eggs for thousands of dollars to pay expenses. The price for such eggs has more than doubled in six months because infertile couples are now competing for them. We can predict that with such demand, some genetically superior but mercenary women will become pregnant just to abort a girl fetus and sell her viable eggs. Any laboratory can now readily obtain quality eggs and sperm from corpses donated to science. Researchers know a human is there when the chromosome count is 46, cells are multiplying, and that life is a continuum which begins at the moment of fertilization.
