In-Vitro Fertilisation is an assisted reproduction technique that consists in fertilising the oocyte with the spermatozoid in the laboratory. To carry out this treatment, first of all a hormone stimulation treatment will have to be carried out with an ovarian puncture to obtain the oocytes. The same day as the puncture there will have to be a sperm sample. From here, the oocytes and spermatozoids are put in contact with one another, so that fertilisation occurs naturally (conventional IVF) or by micro-injecting the spermatozoids, and this technique is called ICSI (Intracytoplasmic Sperm Injection). The resulting embryos will be cultivated to be subsequently placed inside the maternal uterus. The spermatozoids used can be isolated from a semen sample (from the husband/partner or an anonymous donor) or obtained through a testicular biopsy.
It is a moreinvasive technique, but also more effective than artificial insemination. The pregnancy ratevaries according to the woman’s age.
