We can not find any facts on the rate of infertility in the US,
particularly how it has changed in the last 5, 10, 20 years.    We
need statistics and their sources for:  US Infertility rates over the
last 5, 10, 20 years AND any facts on the increase in use of IVF, IVF
clinics, etc.  Any indicator of how changes in infertility and the
growth of fertility treatments as a result.

Greetings Loebandco,
I looked around the Internet and fished out these statistics websites.
It was hard to come by any year-by-year statistics, so I hope these
will do:

The Fertility Race Statistics
http://www.americanradioworks.org/features/fertility_race/common/stats.shtml
"In 1995 2.1 million, or 7.1% of the nation's married couples were
infertile. There were 2.3 million in 1988 and 2.4 in 1982."

AdoptionStatistics.com - Statistics on Infertility/Impaired Fecundity
http://statistics.adoption.com/infertility_impaired_fecundity.php
"- About 6.1 million women experienced impaired fecundity  in 1995,
compared with 4.9 million in 1988. The percent with impaired fecundity
increased to 10.2% in 1995 from 8.4% in 1988. Some of this increase is
due to the aging of the baby boom generation.(Fertility, Family
Planning, and Women's Health, 1997)
- There were 2.1 million infertile couples in 1995, compared to 2.3
million in 1988 and 2.4 million in 1982. (Freundlich, 1998)"
