What is in vitro fertilisation?
It is an assisted reproduction treatment involving the union of an oocyte with a sperm in the laboratory in order to obtain good quality embryos which, after being transferred to the mother’s uterus, can result in a pregnancy.
First appointment: In this first consultation, the problem is discussed and after a medical assessment, the necessary tests for both members of the couple are requested. These tests are essential to determine the cause of the infertility and to identify the most appropriate technique for each couple.
What does in vitro fertilisation entail?
The first step is an ovarian stimulation and controlled ovulation induction through medication. The objective is to stimulate ovulation to obtain an appropriate number of oocytes for the laboratory work, increasing the possibility of success. All the treatments are personalised and the patient is monitored during the days when she is administered the medication.
The second step is to extract the oocytes vaginally by means of an ovarian puncture, with the patient sedated. The oocytes are then fertilised in the lab with the male sperm. Between 16 and 18 hours later, the oocytes are checked to see if they have been fertilised and the couple is informed of the results.
After 5 days, the fertilised oocytes are examined to check if they have divided. On the fifth day, the intrauterine transfer of the embryos is performed when they have reached the blastocyst stage.
Whenever possible, the highest quality blastocyst will be transferred. The transfer is performed in the surgery for its closeness to the lab and for aseptic reasons. This is a pain-free process that does not require sedation. If high-quality embryos are achieved, a single blastocyst will be effectively transferred to prevent a multiple pregnancy. If more optimal embryos are achieved, they will be vitrified in order to be used in another cycle if the pregnancy is not successful or a second child is sought.
We will let you know the best date to have a blood pregnancy test, which tends to be 8 days after the transfer. You will be able to lead a normal life during that time, although high-intensity activities are not recommended.
Our success rates
In vitro fertilisation offers higher pregnancy rates than other less complex assisted reproduction treatments, such as artificial insemination.
- Positives after first transfer: 64.3 %
- Positives after second transfer: 76.3 %
- Positives after third transfer: 78.9 %
