Success rate declines after 2nd or 3rd fertility treatment

August 4, 2010

New research done at the University of California studied success rates of 408 couples using either fertility drugs, intrauterine insemination, or in vitro fertilization. In each of the three treatment options, success rates declined after either the second or third attempt.

The study's authors say the benefits of treatment are most effective on the first try, and do not continue indefinitely.

The findings are published in the journal Fertility and Sterility.
