title: Relationship between the timing of hysterosalpingography before gamete intrafallopian transfer and the subsequent fertility outcome.
abstract: OBJECTIVE
  To investigate the prognostic significance of hysterosalpingography carried out before one-sided gamete intrafallopian transfer for unexplained infertility.
  
  
  METHODS
  Fifty-nine first gamete intrafallopian transfer cycles in 59 couples with unexplained infertility were evaluated in two groups: 30 women with a hysterosalpingogram carried out 1-6 months prior to gamete intrafallopian transfer procedure combined with diagnostic laparoscopy, and 29 women with a hysterosalpingogram carried out during any other interval up to 2 years. The outcome measures were biochemical pregnancy, clinical pregnancy, miscarriage, preterm delivery, and term delivery. Groups were compared using Student's t-test and chi-squared tests. Logistic regression was used to predict the effects of hysterosalpingography on subsequent fertility outcomes.
  
  
  RESULTS
  Univariate analysis yielded no significant differences across groups regarding the baseline characteristics and outcome measures. When confounding factors were controlled, carrying out hysterosalpingography at some time before 6 months of gamete intrafallopian transfer was associated with 5.2- and 3.4-fold increased clinical pregnancy and term delivery rates, respectively.
  
  
  CONCLUSIONS
  An additional hysterosalpingography at most 6 months prior to gamete intrafallopian transfer procedure might improve fertility prospects. This effect could be attributed to proper selection of the fallopian tube for cannulation during transfer or some therapeutic effect of hysterosalpingography.
