Does the Air-bubble Location Influence on the Implantation Rate — TRANSFER  

Embryo Disorder Clinical Trial

Official title: Evaluation of the Implantation Rate Depending on the Air Bubble Location Through Ultrasound Into the Uterine Cavity in Pre-embryo Transfer

Status Completed

Clinical Trial Summary

The main objective of the study is to evaluate whether there is any association between the location into the uterine cavity, where the air bubbles containing the pre-embryos were placed, and the implantation rate. Therefore, the images generated during pre-embryos transfer are available in our database and studied retrospectively.

Clinical Trial Description

The success of a reproductive treatment is determined by three variables: the pre-embryo quality, endometrial receptiveness and pre-embryo transfer. Several previous studies show a lack of agreement concerning the greatest measurement. For instance, some of them refer to the distance between the catheter and the uterine fundus, whereas some others take as a reference the air-bubble where the pre-embryos were placed.

It is for this reason that in the present study, we aim to evaluate the air bubble location ratio into the uterine cavity with reproductive success, taking into account the different variables to reach success. That is, embryo characteristics (quality, development day) endometrium preparation (cycle type, hormone levels on day 5) and even the transfer procedure (type of catheter, blood, difficulty channeling).

It is a study that aims to collect data from January 2013 to october 2019. To this end, the images generated during pre-embryos transfer are analyzed retrospectively. Therefore, it is evaluated the existing differences on implantation rate according to air-bubble placement into uterine cavity during the transfer procedure. ;
