China's decision to allow all married couples to have two children has led to a surge in demand for in vitro fertilization (IVF) among older women seeking a second child. The number of women seeking IVF from one private Beijing hospital rose 20% since the start of the year. Most patients are now over age 40, and some near 50 years old, seeking to have a child as soon as possible after deferred dreams of a second child under China's previous one-child policy. The rise in IVF highlights shifting attitudes towards fertility treatments in China.
