Improved medical technology has contributed to declining infertility rates among US women since the mid-1960s. However, the decades-long trend toward having children later in life means millions of women still have difficulties getting pregnant or carrying a pregnancy through to a live birth.
A report from the National Center for Health Statistics shows that during 2006 to 2010, the percentage of married women aged 15 to 44 years who were infertile decreased to 6% from 8.5% in 1982 and 11.2% in 1965. In married women the same age, the percentage with problems conceiving or delivering a live infant increased from 11% in 1982 to 15% in 2002 but decreased to 12% in 2006 to 2010.
