A trial or mock embryo transfer (ET) may influence pregnancy rates and it performed prior to ET allows the clinician to assess the uterine cavity and the utero-cervical angle. The aim of this study is to compare the consistency of the type of ET in mock ET with real ET.
Material & Methods
A retrospective comparative analysis of patients who underwent in vitro fertilization or ICSI cycle from January 2014 to December 2014 in Halim Fertility Center was done. The type of transfer was divided into two groups: ‘easy’ or ‘difficult’. An easy ET was defined as a transfer that occurred without the use of manipulation or other instrumentation and difficult ET was considered when additional instrumentation was required.
From the study, 103 patients who underwent Mock-ET, we found 58 patients (56.3%) with easy ET and 45 patients (43.7%) with difficult ET, which with hard catheter ET in 17 patients (16.5%), with osfander assistance in 20 patients (19.4%) and with stylet in 8 patients (7,8%). 58 patients with Easy Mock ET group were entirely easy real ET (100%) and 45 patients with difficult Mock ET group also entirely were difficult real ET (100%). The Statistical analysis shows no significant difference between the mock ET and real ET groups (p>0,05). In easy real ET, clinical pregnancy rates were 32.8% and in difficult real ET, clinical pregnancy rates were 26.7% with no significant difference between the groups (p>0,05).
Mock ET prior to the treatment cycle is consistent with real ET.
