Objective: To assess the degree of utero-stimulation induced by transcervical introduction of I catheter as ill mock ET.
Design: Prospective study.
Setting: Reproductive medicine unit.
Patient(s): Eighty volunteers undergoing mild ovarian stimulation and IUI.
Intervention(s): Just before IUI, women had uterine contraction (UC) frequency assessed with 2-minute sagittal ultrasound scans of the uterus (precatheter measurement). Thereafter, one of three types of catheters, each with a different stiffness level (low, n = 25, medium, n = 30; or high, n = 25) was introduced into the cervix up to C the inner cervical os, then immediately withdrawn, and the UC frequency reassessed (postcatheter measurement).
Main Outcome Measure(s): Percentage change in UC frequency.
Result(s): Median (range) UC frequency was not significantly different at pre- and postcatheter measurements: 2.0 (0.0-4.5) UC per minute and 2.2 (0.0-5.5) UC per in minute. In addition, the stiffness of the catheter (low, medium or high) did not influence the UC frequency, with median (range) percentage of change from pre- to postcatheter measurement at 0 (-100% to +75%), 0 (-100% to + 100%), and 0 (-40% to + 100%), respectively.
Conclusion(s): The introduction of,I catheter LIP to the inner cervical os, as usually performed in mock ET does not stimulate uterine contraction frequency, irrespective of catheter stiffness. (Fertil Steril (R) 2010;93:1343-6.
