We all probably know someone who was conceived by in vitro fertilization (IVF). The "father of the test tube baby," Robert G. Edwards, won the Nobel Prize for medicine. On 25 July, 1978, the first "test tube baby" was born. You can read about Louise Brown on Wikipedia.
It's quite amazing to see that advances in medical technology have contributed to over 4 million births through in vitro fertilization. What will be next? There's no doubt that we'll eventually face some deep ethical and moral issues as we try to control human reproduction.
