Pregnancy Clinical Trial
Official title:
Position Of The Tip Of The Inner Catheter And Air Bubbles As Predictors Of Pregnancy During ICSI Cycles:Prospective Observational Study
Position of the tip of the inner catheter and air bubbles detection (at time,5min 10min)during embryo transfer influence the pregnancy rate in ICSI cycles .
The aim of this study is to assess the relationship between the position of the tip of the
inner catheter, the position of the air bubbles (at time , 5 min ,10 min )after embryo
transfer and pregnancy rate outcome in ICSI cycles. Most IVF teams consider not touching the
endometrium and the uterine fundus with replacement of the embryos in the lumen of the
endometrial cavity the most important factors for successful embryo transfer, it is highly
recommended to use agents that can facilitate a smooth embryo transfer and reduce unintended
stimulation of the fundus, for example the application of soft-tipped catheters, which can
improve pregnancy rate.
The advantage of using the air and liquid content for catheter loading is to prevent the
embryo from adhering to the wall of the catheter at the time of injection.The presence of
two air bubbles on both sides of the medium that contains the embryo prevents the transfer
of the embryo within the catheter and beside, in the transfer under ultrasonographic
guidance, the air bubbles are often considered a marker for the embryo's position in the
uterus.
