“…The degree of difficulty during the transfer and the influence of the manipulating physician are the main factors affecting the outcome (1)(2)(3)(4)(5). The former has been characterized by the type of catheter (3), the presence of blood or mucus (4), and also the time spent for the procedure (5). It has been shown that difficult transfers are associated with a reduced implantation rate (1,2).…”

“…Although studies indicate that minimizing the total duration of the ET process may affect the clinical success (7), there is not enough proof to agree on the strict idea that shortening the ET process's total period will enhance clinical success. It is propounded that when good-quality embryos are transferred, the clinical success rate will not decrease despite the extended ET period (12). Also, the recent guideline on embryo transfer of the American Society for Reproductive Medicine did not focus on any cut-off values for the duration of the ET (13).…”

OBJECTIVE: To evaluate the effect of the embryo transfer duration of standard and simple embryo transfer method. STUDY DESIGN: This study was a retrospective cohort study conducted at a tertiary ART Centre, between June 2018- September 2018. Day 5 fresh embryo transferred patients aged between 18 - 40, BMI <35 kg/m2 without uterine pathology were enrolled in the study. Patients were divided into two groups. Group-1 consisted of patients who had successful implantation and Group-2 consisted of patients who did not have implantation. Groups were compared according to their embryo transfer durations. Ninety-two patients were enrolled in the study. Also, sub-steps of as; cleaning of the cervical mucus and placing the outer catheter in the cervix, loading the embryo to the catheter, the period between embryo loading and embryo transfer, and following that, time spent for retracting the outer catheter evaluated. RESULTS: Between Group-1 and Group-2, there was no significant difference for the period of cervical cleaning and placing the outer catheter into the cervix (Respectively; 63 sec vs. 76 sec; p=0.18), the period of embryo loading (Respectively; 69sec vs. 71sec; p=0.46), the period between embryo loading and embryo transfer (Respectively; 10 sec vs. 10 sec; p=0.74, retracing the outer catheter (Respectively; 25.5sec vs. 24sec; p=0.42 and the total period of embryo transfer (182sec vs. 182.5 sec; p=0.55). CONCLUSION: The embryo transfer duration is not related to implantation rates. The duration of the embryo transfer process steps is not a distinguishing factor if a good-quality embryo transfer is done.

“…Comparatively, Matorras and colleagues found a significant decrease in pregnancy rates of 19.1% when transfer time was greater than 120 seconds versus 31.6-38.9% when transfer time was less (p < 0.05). 96,97 With the potential for embryos to be adversely affected by exposure to the environment, the safest technique may be to attempt to minimize the interval time as much as possible.…”

Optimal Oocyte Retrieval and Embryo Transfer Techniques: Where We Are and How We Got Here

Oocyte retrieval is most safely accomplished with conscious sedation via a transvaginal approach under ultrasound guidance with low-pressure aspiration. Follicle flushing has not been shown to improve outcomes. The type of vaginal surgical preparation and the use of antibiotics have not been demonstrated to affect outcomes. As the final step in a rigorous assisted reproductive technology (ART) cycle, precise technique in embryo transfer is essential. Based on current findings, the recommended embryo transfer technique includes the use of an ultrasound-guided transcervical approach with a full bladder using a soft catheter. The transfer depth of the embryo should be in the mid-portion of the uterus with a quick steady insertion followed by pressure on the syringe during withdrawal of the catheter. It is acceptable to encourage immediate ambulation after embryo transfer.
