An observational study in Embryo Disorder, sponsored by IVI Vigo. Completed. Open to female participants aged 30 Years to 50 Years. Per ClinicalTrials.gov, last updated 2020-10-06.
Sponsored by IVI Vigo · Observational
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.
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.
IVI Vigo is the lead sponsor of 9 studies on the registry; none are open to participants now.
Counted across the registry records on this site, refreshed daily.
IVIVigo patients with a normal uterine anatomy and a single good quality embryo to transfer at blastocyst stage, performed by the same gynaecologist using the "three-drop technique" were included. All transfer were atraumatic, without blood presence, using soft catheter and with controlled ultrasound transfer. The distance between the fundus surface and the tip of catheter, the distance between the fundus and the air bubble, the endometrial thickness and the implantation rate were recorded.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
