In Vitro Fertilisation (IVF)

In Vitro Fertilisation involves uniting the ovum with the spermatozoon in the laboratory – in vitro – in order to obtain fertilised embryos for transfer to the mother’s uterus. The fertilisation of the ova can be carried out by means of the conventional IVF technique or by Intracytoplasmic Sperm Injection (ICSI).

In Vitro Fertilization


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 suffering from advanced endometriosis, with probable repercussions on the tubes and on oocyte quality.
  • Situations in which a limited number of oocytes are available.
  • Cases of severe male factor infertility.


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.

We are not the most expensive choice. We offer the most treatment options in order to achieve the best results.


In our assisted reproduction clinics we provide patients with a personalised diagnosis in order to choose the best treatment for each infertility problem..


Ovarian stimulation

Ovarian stimulation during IVF consists of the administration of daily injections which cause the ovaries, instead of producing a single ovum which is what they do naturally each month, to produce more oocytes so that a larger number of embryos can be obtained.

This treatment takes place at IVI assisted reproduction clinics and lasts between 10 to 20 days, depending on the protocol used and the speed of response of each patient. During treatment, a series of 3 or 4 ultrasound scans are carried out and the amount of estradiol in the blood is determined to check that there is normal growth and development of the follicles.

In vitro Fertilisation

Follicular puncture and the laboratory

When we have evidence through the ultrasound scans that the follicles have reached an adequate size, and we consider that there are a suitable number of oocytes, we schedule follicular puncture 36 hours after administering an injection of the hormone hCG which causes the oocytes to mature in a similar way to the way they would in a natural cycle.

Puncture is carried out in the operating theatre under sedation so that the patient does not feel any kind of discomfort during the procedure, which lasts approximately 15 minutes.

In vitro Fertilisation

Fertilisation of the oocytes

Once we have the oocytes after follicular puncture, and the spermatozoa, which are normally obtained from a semen sample from the male partner, insemination of the ova begins.

This process can be performed via conventional IVF, which involves placing an oocyte surrounded by spermatozoa in a culture plate, or else via ICSI, which consists of inserting a live spermatozoon into the oocyte by puncturing the latter with the aid of a pipette.

Embryo culture in the laboratory

The resulting embryos are observed in the laboratory day after day and are classified according to their morphology and their ability to divide. Some embryos can become blocked in their development, and these will be discarded as they are considered to be non-viable.

In vitro Fertilisation


Transfer involves inserting the best embryos into the mother’s uterus with the help of a specially designed cannula. The procedure is carried out in an operating theatre, although in this case it is not necessary to use sedation since it is a quick and painless procedure.

Vitrification of the remaining embryos

Once the embryo transfer has been made, we vitrify the remaining good quality embryos so that they can be used in a later cycle without the need for further ovarian stimulation.
