This treatment requires hormonal stimulation to obtain several eggs, which are retrieved by ovarian puncture. They are then fertilised in the laboratory and implanted into the uterus. The aim of this procedure is to obtain embryos of good quality in order to increase the chances of pregnancy. In vitro fertilisation is suitable for treating male and female infertility.
- Using the partner's own eggs and sperm
- Using eggs from an anonymous donor
- With sperm from an anonymous donor
In the first option, both partners are involved in the treatment. Both a semen sample and hormonal stimulation are required to obtain high-quality embryos that increase the chances of pregnancy.
In the case of treatment with anonymous donors (second and third options), it is important to note that Spanish legislation allows anonymous donation of sperm and oocytes. The donor's identity remains secret and the donor has no right to know the identity of the baby conceived with the donated egg.
When it comes to donor screening and approval, IVF-Spain is committed to being one step ahead of the legal requirements of Spanish legislation: We carry out additional tests with the aim of using only oocytes and donor sperm with the highest possible guarantee of safety.
Intracytoplasmic sperm injection In IVF with ICSI, the embryologist selects the spermatozoon and fertilises the egg by means of microinjection. This fertilisation technique is used when the sperm sample is of low quality. Occasionally, when there is a considerable number of good quality eggs, embryologists use both fertilisation techniques simultaneously: Half of the eggs are fertilised by conventional IVF and the other half by ICSI.
