assisted reproduction. Here's what you'll find online:
The 18 Ways (And Then Some)
NOVA producer Sarah Holt tells how surprised she was to learn, during an interview with assisted-reproduction expert Dr. Jamie Grifo, that there are 18 ways to make a baby—and then to find out there are actually many more. Herewith the ever-growing list.
On Human Cloning
Should human beings be cloned? In this feature, we present the views of three scientists who have radically different answers to that question: by all means (Princeton molecular biologist Dr. Lee Silver), in time, perhaps (Dr. Don Wolf, senior scientist at the Oregon Regional Primate Research Center), and absolutely not (MIT's Dr. Rudolf Jaenisch).
Fertility Throughout Life
Many components of our reproductive lives begin long before puberty and extend well into our later years. In this feature, explore the ebbs and flows of fertility in men and women, from infancy through adulthood and into old age.
How Cells Divide (Hot Science)
Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In this step-by-step explanation, learn about mitosis and meiosis, the two types of cell division.
