Over past 20 years infertility rates remain unchanged

02.09.2013

A study by international researchers published in PLOS Medicine finds infertility rates have hardly changed over the past 20 years and in 2010, almost 50 million couples worldwide were unable to have a child after five years of trying.

In an analysis of 277 national surveys, the authors, led by Gretchen Stevens from the World Health Organization, estimated the levels and trends of infertility in 190 countries from 1990 to 2010. They found that in 2010, 1.9% of women aged 20 years who wanted to have children were unable to have their first live birth (primary infertility), and 10.5% of women who had previously given birth were unable to have another baby (secondary infertility)—a total of 48.5 million couples.
