Approaching the Limit: Long-Term Trends in Late and Very Late Fertility.

This article discusses how European women are historically bearing their first children later than ever before. In the United States and other countries, entry into parenthood is also seeing delays. Many experts argue that such fertility trends in developed countries are characterized by increasing, persistent, and arguably irreversible delays in childbearing in many socioeconomic conditions. Many of the informal age deadlines for childbearing are apparently being challenged and biological limits are being pushed. The article also presents information about the physiological aspects of late fertility and discusses the effect of new technologies on conception and pregnancy. Sweden's late and very late fertility is also examined.
