A total of 350 women due to undergo gamete intrafallopian transfer wer
e scanned vaginally on the operation day and the findings were compare
d with those recorded 2 days previously when human chorionic gonadotro
pin was administered. The aim was to assess the clinical value of ultr
asound assessment on the operation day, especially from a prognostic p
oint of view. Seven women (2%) were found to have already ovulated and
evidence of imminent ovulation was detected in another 27 cases (7.7%
). There were more frequent and more marked increases in the number of
follicles with a diameter of > 14 mm, in the diameter of the leading
follicle and in the endometrial thickness in the women who subsequentl
y conceived. The endometrial reflectivity was brighter than the myomet
rium (grade A) in 77.3% of the women who conceived, compared with only
37.5% of those who did not conceive. These differences were statistic
ally significant. It was concluded that follicular and endometrial cha
nges recorded on the day of gamete intrafallopian transfer may have a
prognostic value, as the pregnancy rate was higher in women who had th
e favorable ultrasonographic features outlined in the study.
