Abstract

PURPOSE:

To evaluate the influence of ultrasound guidance during intrauterine insemination (IUI) on pregnancy rates (PRs). The impacts of two different groups of providers were also investigated.

METHODS:

Study population consisted of 387 gonadotropin stimulated IUI cycles performed for unexplained infertility. The patients were randomized into two groups as ultrasound-guided IUI (n = 180) and classical IUI (n = 207). Pregnancy rates were compared. Two groups were further analyzed based on the experience of the provider (senior versus junior subgroups) who performed IUI.

RESULTS:

Pregnancy rates were higher in the ultrasound-guided IUI group (17.2%) compared to the classical IUI (10.1 %) (p = 0.042). In further analysis based on the experience of the provider; in the classical IUI group, PRs were similar for both subgroups, however, in the ultrasound-guided group it was higher when IUI was performed by a senior physician (21.7 versus 9.2%, p = 0.033). Logistic regression revealed that the experience of the provider was the independent variable for improved PRs.

CONCLUSIONS:

Ultrasound guidance improves PRs only when a senior provider performs the IUI procedure. It seems that the experience of the provider physician is one of the determinants of IUI success.
