The in vitro fertilization (IVF) is the placement of sperm cells around each oocyte, so as to obtain embryos already fertilized for transfer to the maternal uterus.
The in vitro fertilisation (IVF) is the placement of sperm cells around each oocyte, so as to obtain embryos already fertilized for transfer to the maternal uterus.
The oocytes are collected from ovaries, and then fertilized with sperm, in the middle of the laboratory. The embryos thus obtained are transferred, later, to the uterus of the woman.
In these cases, fertilization occurs outside the body of the woman, contrary to what happens in other cases of reproduction medically assisted.
HOW TO CHOOSE THE BEST TECHNIQUE OF FERTILIZATION IN VITRO?
Insemination of oocytes can be accomplished using the technique of in vitro fertilization, conventional, or Injection Intracytoplasmic Sperm (ICSI), allowing, this, to achieve pregnancy success in couples who have been diagnosed with a bad quality in the semen sample of the man.
It is recommended IVF with semen of the donor, in cases where there is:
- A bad quality sperm;
- Previous failure of fertilization with semen itself;
- Poor quality embryo;
- Failure of implantation, repeated;
- Suspicious of a male factor as the primary cause;
- Men with a genetic disease that cannot be studied in the embryos.
In vitro fertilization is indicated in cases of obstruction of the fallopian Tubes, when there are slight changes in semen analysis, in cases of endometriosis or to treat infertility of unknown causes.
Used, also, to this treatment when there is a situation of infertility for more than two years, or when the woman has more than 35 years of age.
In Portugal, the first child resulting from a treatment in vitro fertilization was born in 1986, after a treatment is carried out in the Hospital of Santa Maria, in Lisbon.
Today, we carry out hundreds of thousands of cycles of IVF across the world, and this is a safe procedure, well established and with an excellent percentage of success.
AS IS DONE IN THE TREATMENT OF IN VITRO FERTILIZATION?
In Ferticentro the treatment of in vitro fertilization is done in the following way:
The couple starts by being diagnosed and indicated for the treatment of in vitro fertilization.
They explained all the technical details about how will take place during the treatment and taught the administration of the drugs used in the stimulation ovária.
On the 3rd day of the menstrual cycle, start the administration via injectable Suprefact and Menopur or any other medicine ovulation inducer, according to the instructions that were given previously by the doctor.
Are these that will stimulate the ovaries to produce more oocytes (eggs) than usual.
By around the 5th day of the cycle, to make sure the administration of estradiol and adjusts the dose of the Menopur.
Between the 7th and 10th day, repeats the determination of estradiol and is the first ultrasound control.Back to adjust the dose of Menopur. May be needed one or two more ultrasounds.
The development of oocytes is controlled by performing periodic scans and blood tests, to determine the levels of some hormones associated with the maturation process of the eggs.
When the follicles in the ovaries are properly developed triggers-if ovulation with Ovitrelle.
Is made to puncture the follicular to the collection of eggs from the ovaries. Punching is the operation of collection of the oocytes from the ovaries.
Should be performed 35 to 36 hours after the administration of Ovitrelle.
The puncture is made with the control echographic and consists in the introduction into the vagina, of a very fine needle, which will allow the collection of oocytes from each ovary.
The eggs are then fertilized in the middle of the laboratory. To obtain the embryos developed in the laboratory.
Transfer 1, 2, or, more rarely, 3 embryos to the uterus, 2, 3, or 5 days after the puncture.
The remaining embryos that are not used in the treatment and present conditions of viability, they can be frozen and used in a loop to perform later on, for example, in cases in which the couple intends to have more than one child, or if the first attempt fails.
WHAT ARE THE ADVERSE REACTIONS TO THE TREATMENT?
Like any other treatment, in vitro fertilization may cause adverse reactions.
Although this type of treatment couples are always accompanied by doctors and all treatments are carried out in accordance with the stringent standards of international security, it is important that the couple be aware of the possibility of the existence of unpleasant situations.
As a rule, when they occur, these reactions have character moderate and passenger.
THE MOST FREQUENT SYMPTOMS
SYMPTOMS MORE RARE
In situations that are more rare, can occur the Syndrome of Hyperstimulation Ovarian, which is a reaction to excessive and potentially dangerous to drugs used in the stimulation of ovarian.
In these situations, there is accumulation of fluid and cyst formation in the ovaries.
The main symptoms of this situation are:
- Pelvic pain and/or abdominal;
- Shortness of breath;
- In more serious cases, this situation can lead to interruption of treatment or admission to a hospital.
