During the IVF (in-vitro fertilization) process, we have extra embryos that may remain. This is completely normal. It is possible to freeze the embryos, which is a procedure that enables the woman to save embryos in the event that a future attempt is necessary. An embryo can be frozen cryogenically for a maximum of 10 years. You can learn more about the implications of the process when you click here.
If you are particularly in a hurry, you should be aware of the fact that this is a procedure that is minimally invasive or non-invasive. Embryos are frozen and implanted right into the uterus of the woman when appropriate. Frozen Embryo Transfer (commonly referred to as FET) can help women that have uterine based problems. Simply put, if the woman cannot carry out a pregnancy or there are some disorders present, this is a procedure that can help.
In most situations FET is associated with the in-vitro fertilization process. The woman donates eggs and the man donates sperm. These two are combined so that embryos are created. Embryos are then studied to see if they are viable. Those that develop normally will be selected and eventually implanted. After a conversation with the doctor, a decision about the number of embryos that would be implanted is started. The rest is normally cryopreserved.
Embryos can be frozen for up to 10 years and be used whenever you want to. With this in mind, it is normal to be faced with a situation in which a woman would want to freeze embryos even if the IVF procedure will not be performed in the near future. Make sure that you always discuss everything related to the procedure with your doctor since this will help you out a lot more than you may believe.
As it is time to use embryos that were frozen, thawing at room temperature is usually the first step taken, normally one day before a transfer. Cryoprotectant is to be washed away during solution soaking series. Embryos are mixed with medium solution and are only warmed at body temperature so that everything would be as natural as possible.
Implantation timing varies from one woman to the next but the doctor dos monitor for that. In most cases there are 3 or 4 embryos that would be transferred at one time in order to increase implantation chances. Ovarian follicles are normally suppressed with the use of medication. Uterine lining is then developed by using other drugs. Doctors usually use ultrasound in order to determine when embryos should be transferred.
The actual frozen embryo transfer is not at all difficult to carry out. Embryos will easily be transferred inside your uterus through the cervix. The procedure is just minimally invasive. The procedure is just slightly uncomfortable. Success rates vary based on individual conditions. That is why it is imperative that all options are discussed with the doctor so that pregnancy chances can be increased. Various options are available for that but it is important that the communication channel between you and the doctor is proper.
