In releasing the data, the American Fertility Society cited overall success rates for 1985 and 1986 as 14.1% and 16.9%, respectively. Those figures are based on the number of clinical pregnancies per embryo transfer, figures which some fertility specialists think may be misinterpreted by patients (JAMA 1988;259:464-469).
