Martha Padgett gave birth to quadruplets in Riverside, Calif., in July, but she only did half the work. The other two babies were born to her partner, Karen Wesolowski, using Padgett's eggs and the same sperm donor, and whose two came along 22 hours after Padgett's two. The women carried two fertilized eggs each only because they had failed five times before with in-vitro fertilization and just wanted to improve the odds of having at least one child between them.
