Fertilization

In Vitro fertilization is defined as the union of an oocyte and sperm outside the body, in a highly specialized In Vitro fertilization laboratory, and the subsequent transfer of the embryos obtained inside the patient’s uterus.

In Vitro Fertilization supports patients with the following conditions, among others

Ovulatory disorders.
Blocked or damaged fallopian tubes.
Endometriosis.
Low sperm quality.

PROCEDIMIENTO

There are 6 basic steps for In Vitro Fertilization

Ovarian stimulation

In this step, women start treatment with pills or injections containing hormones. The goal is to stimulate the follicles in the ovaries to grow so that the eggs begin to mature.

This step lasts approximately 10 days and during it ultrasound evaluations are performed to verify that the development of the follicles is adequate.

Obtaining the mature oocytes

The woman is operated on in an operating room specialized in human reproduction treatments where she is given anesthesia by sedation and through a painless procedure the mature oocytes are extracted from her body via the vagina.

ICSI or In Vitro Fertilization

It consists of the classification of the oocytes that were extracted and is performed within the IVF laboratory. Here these oocytes by means of ICSI (Intracytoplasmic Sperm Injection) or in vitro fertilization are united with the spermatozoon and are maintained in culture media appropriate for their development. 24 hours after the union, an evaluation is made of how many of these oocytes have fertilized adequately.

Embryo culture

The oocytes that were fertilized correctly remain in suitable culture media that allow their correct development until day 3 or 5 of In Vitro development (this last phase is called the blastocyst stage).

Embryo transfer

It consists of selecting the embryo or embryos with the best morphological or genetic quality so that they can be transferred to the woman’s uterus with a very flexible catheter. For the embryo transfer the patient needs to return to the clinic, this is a painless procedure that does not require anesthesia.

Freezing of good quality embryos that were not transferred and that can be used in a next attempt

This point is after the embryo transfer. Embryos that had an adequate development, but were not used for transfer, are evaluated, so they are vitrified (cryopreservation of cells at -196°C in liquid nitrogen) and stored so that they can be used in another occasion.

decision to try.

METHOD CHARACTERISTICS

It is the assisted reproduction treatment with the highest probability of success.
Due to the age of the technique (since 1978), its effectiveness and reliability are more than proven.
The risk of complications is very low.
By observing the extracted oocytes, sperm and embryos formed under the microscope, valuable information is obtained about the possible cause of the couple’s infertility and any morphological anomalies.
To be able to freeze the remaining embryos of good quality from the treatment in case another attempt is required.

SUCCESS

RATE

Making the decision on which assisted reproduction center to choose is difficult as multiple factors must be considered.

We want to support you in this situation, so we share here the success rates that our fertility clinic manages in achieving pregnancies with an In Vitro fertilization treatment.

Consult a specialist in assisted reproduction to determine the appropriate method for your needs.
