In Vitro Fertilisation (IVF)
with a cycle of ovulatory stimulation with the goal of making several
eggs (ova) mature, which are then recovered and cultured with a
determined quantity of sperm cells that have been previously selected
through the process of sperm capacitation. Once the highest-quality
embryos are selected, they are transferred to the uterus two or three
days after follicular puncture (egg retrieval).
Sperm microinjection (ICSI)
The sperm microinjection (ICSI) technique
consists of the introduction of a sperm cell into the interior part of
an egg. It can even be carried out with sperm samples of very low
quality, as only one sperm cell per retrieved egg is required. It is
also a possibility for azoospermic patients who have had a testicular
biopsy. Just as in IVF, egg retrieval (follicular puncture) is
facilitated by ultrasound, following ovarian stimulation. The eggs that
are fertilised will then be cultured in the laboratory until they are
transferred to the uterus, just as in IVF.

Preimplantation Genetic Diagnosis (PGD): This
technique is called for when there is a need to avoid the birth of
babies with genetic or chromosomal abnormalities. It consists of
performing a biopsy of each embryo obtained following a process of
IVF-ICSI in order to extract a cell and submit it to an exhaustive
genetic analysis so that healthy embryos can be differentiated from
those carrying some kind of pathology.
Clinica Medrano has an authorised embryo bank, originating from couples
who have undergone cycles of IVF-ICSI. Viable embryos that have not
been transferred to the woman are cryoconserved, as long as there is
patient consent, for whatever use that is established by law. Therefore,
possible uses for these embryos may include their use by the same woman
or partner in later cycles, donation to other couples for reproductive
purposes, or donation to research.
There are many couples who, for different reasons, must resort to using
eggs from donors in order to solve their infertility problems. Thanks
to the enormous generosity of many people, these couples can enjoy
parenthood. The fact that donors are young women allows for excellent
rates of gestation to be obtained.
