My first ideas of human in vitro fertilization (IVF) arose with my Ph.D. in Edinburgh University in the early 1950s. Supervised by Alan Beatty, my research was based on his work on altering chromosomal complements in mouse embryos.
Neither sex, without some fertilization of the complimentary characters of the other, is capable of the highest reaches of human endeavor.
Like the 'test tube babies' born of in vitro fertilization, cloned children need not be identifiable, much less freaks or outcasts.
You cannot be against embryonic stem cell research and be intellectually and therefore morally consistent, if you're not also against in vitro fertilization.
Nobody knew in advance that in vitro fertilization would be, by and large, safe.
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.
As a physician, I know that human life begins with fertilization, and I remain committed to ending abortion in all stages of pregnancy. I will continue to fight this atrocity on behalf of the unborn, and I hope my colleagues will support me in doing so.
The moment-of-conception fallacy implies that fertilization is a simple process with never a doubt as to whether it has or has not happened.
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.
If you are in support of in vitro fertilization, then you have to recognize that human embryos are being created in excess of what can be used safely to reimplant for a pregnancy. So they're going to end up being discarded.
