We refer to In Vitro Fertilization (IVF) when the eggs extracted from a woman are fertilized outside her body.
This treatment may be done using two different techniques:
Conventional IVF: the eggs are mixed with the partner’s or donor’s sperm and are incubated in the laboratory.
Intracytoplasmic Sperm Injection (ICSI): a single sperm is placed inside each one of the eggs that were harvested through ovarian puncture.
In vitro fertilization is suitable for:
- Women with damaged Fallopian tubes, endometriosis, etc.
- Women with a low ovarian reserve.
- Men with an insufficient number of sperm to perform artificial insemination.
- Couples with four or more unsuccessful attempts at artificial insemination.
The process in 5 steps
This involves stimulating the ovary in a controlled manner so that it produces a greater number of eggs.
Extraction of eggs
Extraction of eggs is performed under sedation. The procedure lasts about 15 minutes. The patient is released 3 hours later after undergoing the necessary check-ups.
A semen sample is obtained and then prepared for subsequent insemination, either by conventional IVF or ICSI, depending on the patient’s diagnosis. To assist fertilization, the laboratory recreates the woman’s body temperature.
In vitro culturing of fertilized eggs
After 18 hours the eggs are examined to determine how many have been fertilized. These are then cultured in the laboratory for 5 days until blastocysts form. Thanks to advanced culturing techniques, enhanced assessment of the embryo’s quality can be conducted, as well as improved selection of the embryo to be transferred.
After identifying the best embryo, it is transferred to the uterine cavity. The surplus embryos will be vitrified (frozen), if their morphology is satisfactory.
