O-022. Uterine junctional zone contractions during an IVF and embryo transfer cycle

Uterine junctional zone contractions during assisted reproduction cycles.

This study was designed to assess junctional zone contractions (JZ) during cycles of in-vitro fertilization (IVF) and embryo transfer in oocyte donors exposed to a long protocol regime for ovarian stimulation. Real-time transvaginal ultrasound and advanced audio-visual and computer technology were used to evaluate the contraction pattern, frequency and velocity. At the time of down-regulation J...

Embryo transfer--can we learn anything new from the observation of junctional zone contractions?

To assess whether embryo transfer can alter junctional zone contractility, we studied the effect of easy and difficult mock transfers in 14 oocyte donors during in-vitro fertilization (IVF) cycles. An Echovist bolus (30 microl) was used to represent embryos and transfer medium. An 'easy' transfer was judged to be an atraumatic insertion of the catheter without touching the uterine fundus. A 'di...

I-32: Uterine Factors Are Important for Successful Embryo Transfer After IVF

Embryo transfer (ET) is the final and most crucial step of the IVF procedure, characterized by a close collaboration between the clinician and the embryologist. Several studies have shown improvement in clinical pregnancy rates resulting from a focus on different aspects of the gentle embryo transfer technique. Issues such as impact of physician’s experience, trial transfer, catheter type, embr...

Comparison between Conventional Blind Embryo Transfer and Embryo Transfer Based on Previously Measured Uterine Length

IVF Treatment and Single Embryo Transfer

IVF has been described as one the medical breakthroughs of the 20 th Century. Over 5 million children have been born using the methods first developed by Robert Edwards who died last year. However there is continuing concern about some of the outcomes of IVF treatment (Kamphuis et al., 2014), particularly the high number of multiple births, a problem which became apparent only a few years after...
