After the egg is successfully fertilized by a viable sperm, it travels through the Fallopian tube towards the uterus. It then attaches itself to the lining of the uterus so that it can continue to grow properly. The whole process, from fertilization to implantation, usually takes about 9-10 days.
What is the Frozen Embryo Transfer Process?
Frozen Embryo transfer a process within the IVF or ART, Aided Reproductive Technology process. Generally, embryo transfer is completed forty eight hours after the egg has been inseminated by the sperm cell. At this point, cell division is already occurring and there will be a minimum of four cells visible inside the embryo once it’s examined under the microscope.
How Does Frozen Embryo Transfer Work?
The frozen embryo transfer process is very simple. For the bulk of women, transferring the embryo is simple and painless. it’s done once the woman is conscious, therefore no anaesthetic is needed. A vaginal speculum is used to open the walls of the vagina that the cervix may be clearly seen. A fine plastic tubing is then fed up through the vagina and thru the centre of the cervix into the uterus. Some doctors can use ultrasound to assist them guide the top of the tubing to the perfect location within the uterus before the embryo is injected.
It may be tough to pass the tubing through the cervix if it’s scarred or if the lady has had previous surgery that has caused her cervical opening to become restricted. A dilatation is typically necessary before the embryo transfer stage. This then permits the catheter to be pushed gently through the cervix.
How Many Embryos Are Transferred?
Most clinics can currently only transfer two embryos. This will increase the possibilities of a successful pregnancy however limits the chance of triplets and multiples. In previous years there was very little regulation round the numbers of embryos that may well be transferred. currently there are generally more responsible practices being conducted in fertility clinics.
The other issue is that the chance of successful pregnancies from fertility treatments overall has increased.
