Abstract

In table 1 on p. 128 in the article "External human fertilization: an evaluation of policy" by C. Grobstein et al. (14 Oct., p. 127), the number of embryo transfers for Queen Victoria Medical Centre (218) resulted from the 364 laparoscopies of the first two clinical series. The first figure for the percentage of pregnancies per embryo transfer for that center also represents the combined result from the first two clinical series, and the percentage is 20(43/218),not 12.
