In Vitro Fertilisation (IVF)

In vitro fertilisation (IVF) is a well-established technique for creating embryos by fertilizing the egg with the sperm in a laboratory. The resulting embryo(s) can then be transferred to the woman’s uterus. The fertilisation process can be carried out using a conventional IVF technique or by intracytoplasmic sperm injection (ICSI).

What is In Vitro Fertilisation?

In what cases is it indicated?

Semen from the partner

In vitro fertilisation using semen from the couple is recommended for:

  • Patients for whom previous simpler treatments, such as artificial insemination, have failed.
  • Women with an absence of or lesions on the Fallopian tubes. These are important for natural fertilisation or artificial insemination.
  • Women were suffering from advanced endometriosis, with probable repercussions on the tubes and oocyte quality.
  • Situations in which a limited number of oocytes are available.
  • Cases of severe male factor infertility.
Semen from a donor

In vitro fertilisation using semen from a donor is recommended for:

  • Severe male factor infertility, with poor sperm quality.
  • Previous fertilisation failure using semen from the couple.
  • Poor embryo quality or repeated implantation failure in cases in which the main cause is suspected to be a male factor.
  • Men who are carriers of a genetic disease which cannot be studied in the embryos.
  • Women who do not have a male partner.

Estimulación ovárica laboratorio FIV

Ovarian stimulation

The treatment is performed in assisted reproduction clinics, and it takes between 10 to 20 days, depending on the stimulation protocol chosen. Our health professionals will indicate the type of medication and appropriate dosages for each woman, based on each case. The patient will self-administer daily injections which contain hormones. During the process, follicle tracking through transvaginal ultrasound scans will be performed, and serum levels in the blood are also measured to control ovarian follicular growth and maturation.

Oocyte retrieval and laboratory

Oocyte retrieval and laboratory - IVF

The patient attends the clinic to undergo egg retrieval under light sedation to prevent discomfort. The procedure takes 15 minutes and involves a gynaecologist, an embryologist and an anaesthetist.

Fertilisation can be carried out by two methods: conventional IVF, which consists of placing the eggs in contact with sperm in a petri-dish and ICSI, which consists of microinjection of the sperm directly into the mature egg with the help of a pipette.
