FIV/ICSI with sperm donor
There are two different techniques to achieve an In Vitro Fertilisation, the Traditional In Vitro Fertilisation (IVF) and the Intracytoplasmic Sperm Injection (ICSI).
In traditional IVF the egg and sperm are placed in a fertilisation medium in order to get a very similar process to natural fertilization.
ICSI involves the injection of a single sperm into the egg.
Choosing one over the other depends on each particular case. Both techniques can be performed with own eggs and sperm or donor support.
In Spain it is possible to transfer up to 3 embryos at each time.
The eggs are subjected to a culture period and after the fertilisation, whether traditional or ICSI. Then the embryos are grown a few days until the right moment to transfer them.
The embryos are charged into a transfer catheter and are introduced into the uterus without anesthesia in a simple procedure that takes about 15 minutes.
Embryos that have not been used are cryopreserved because it could be necessary to repeat the transfer process.
BEFORE THE PROCEDURE
If patients are using their own sperm and egg cells, they must undergo an extraction process. For egg retrieval women should follow a previous hormone treatment.
The sperm is selected and improved to increase the chances of success.
If patients need an eggs or sperm donor, they should inform the medical centre.
AFTER THE PROCEDURE:
Two weeks after insemination, patients may undergo a pregnancy test to check if she is pregnant.
