In an in vitro fertilization(IVF) procedure, embryo transfer(ET) is not only the final but also the most crucial step. A good embryo transfer determines the probability of success of an IVF cycle, and for this, clinicians and embryologists need to work in close collaboration.
The procedure of Embryo transfer is not painful and anesthesia is generally not needed. We in our clinic follow certain principles like keeping the embryo transfer as atraumatic as possible, an ultrasound-guided transfer always, use of soft embryo transfer catheters, and dropping the embryos at the right place in the uterus.
Many times further improvisation is needed to make the procedure more successful like Trial transfer, aspiration of cervical mucus before the transfer, timely completion of the embryo transfer procedure, and straightening of the utero-cervical angle.
1. After loading technique for the embryo 2. Absence of bacterial contamination 3. Speed of injecting needs to be well controlled 4. Prevention of uterine contractions
It has been seen that the use of antibiotics before the transfer, performing two transfers in the same cycle, prolonged bed rest, and sexual intercourse after the transfer do not impact the outcome of embryo transfer.
What is well-accepted today is the importance of a gentle atraumatic transfer where no damage to the endometrium and minimal uterine contractions are induced. Following embryo transfer, no particular factor other than progesterone luteal phase support has been shown to have a positive effect on pregnancy outcome.
The primal state of infertility is what can be overcome by the process of the transfer and it in the modern sciences with stem cell as such will come into play in the modern future of the transfer. In no time it has come to a point of embryo cloning and will be hugely adopted amongst others.
