Embryo transfer

The transfer of embryos is to introduce into the uterine cavity through the cervix, a very fine plastic tube (catheter) containing the embryos. This method is painless in most cases. Takes place in the gynecological position and takes about 10 minutes.

Number of Embryos Transferred:
The choice of the number of embryo transfer is established between you and your doctor or the doctor who performs the transfer. We routinely transfer 3 embryos, which appears to be a good compromise between a good pregnancy rate and an acceptable rate of multiple pregnancies. In special cases, the number of embryos may be reduced or increased.


The day after collection should call for the results of fertilization. The time of this transfer will be explained. Please respect the time that is given to you. The midwife will suggest IVF possibly a half-hour relaxation session to better relax. After the transfer you will be about 20 minutes in the room where you performed the procedure. During the next few days, you can make a normal life but quiet and resume work without problem, with certain exceptions. You must however avoid long journeys by car, heavy lifting and standing for too long.

Consultation after IVF
Take an appointment with your doctor for a consultation “post-IVF” which is the point in your attempt, and that 3 or 4 weeks after the transfer, so the result is already known.


Difficulties in the transfer
Upon the transfer of embryos in the uterus may present some problems. First the anxious patient can interfere with the proper application of the technique is for a woman’s hypersensitivity to any manipulation, both through the possible somatization in cervico-vaginal spasm. The difficulty that often arises is formed by the arrest of the progression of the catheter through the cervical canal due to stenosis. It classifies transfers in relation to the degree of difficulty encountered in:

a) Transfers easy: The transfer is successful the first time on the catheter and there is a small amount of mucus.

b) Transfers suspected: Those who have difficulty in crossing the orifice inside the uterus or during which you are not sure of the position of the tip of the catheter or, again, after which there is blood on the catheter or uterine orifice inside.

c) Transfers difficult: They require long periods of manipulation to cross the cervix, often require a certain pressure, and sometimes are accompanied by blood loss or need for expansion.

In IVF programs, the fundamental condition that the plant occurs is represented by the synchronization of uterine receptivity and the stage of embryo development. Most of the pregnancies achieved with embryos at 4-8 cell.

After the transfer:
* Avoid excessive anxiety or attention to itself or received from partners, which represent the most wrong in relating how the family environment and with the outside world.

* Lead a life as normal as possible, avoiding abdominal trauma, physical exertion, sexual intercourse, exposure to excessive heat and cold, while also reducing caffeine intake and refraining from smoking as much as possible.

* After 14 days of embryo transfer, if you have not presented a normal menstrual flow, will perform pregnancy test sensitivity to 50 IU or 75 (can use the tests available in pharmacies).

* If the test is negative we recommend to repeat it at a distance of one week and if still negative in absence of a menstrual flow regular contact doctor.

* If you are not established a pregnancy, you will have a regular menstrual flow of approximately 12 days after the transfer and precise than the data that was expected. It is possible that the flow is initially less intense and more painful than usual or that you see clots or blood clots. All this is completely normal and would like to state that under no circumstances you can see the embryos, which at this stage of development, are only visible under a microscope.

* If the test is positive, please contact doctor for further instructions.

* Determined that it is a pregnancy should not discontinue therapy as allocated at the time of the transfer up to 12 weeks of gestation.

* The subsequent course of pregnancy should be followed by your gynecologist bearing in mind that your pregnancy is perfectly normal, but that probably will be unique.
