There are, as is known, insects that die in the moment of fertilization. So it is with all joy: life's highest, most splendid moment of enjoyment is accompanied by death. Soren Kierkegaard
Neither sex, without some fertilization of the complimentary characters of the other, is capable of the highest reaches of human endeavor. Jean-Paul Sartre
You cannot be against embryonic stem cell research and be intellectually and therefore morally consistent, if you're not also against in vitro fertilization. Ron Reagan
One-third of all female infertility is the result of blocked fallopian tubes. If fertilization could be done in the lab and then the fertilized egg implanted in the womb, it would get around that problem. Millions of women who cannot have children would suddenly be able to. James D. Watson
Like the 'test tube babies' born of in vitro fertilization, cloned children need not be identifiable, much less freaks or outcasts. Virginia Postrel
