Understanding In Vitro Fertilization Step by Step

In vitro fertilization (IVF) is an assisted technique that has brought hope to many couples facing fertility challenges. Although the process is essentially the same, the individual experience may vary for each woman. Here's a step-by-step look at the IVF process.

1. Stimulation of the ovaries


Through hormonal injections, the aim is to stimulate the ovaries to generate multiple follicles. Each follicle houses an immature egg, which when mature will be ready to be fertilized.

Expected result: The growth of several follicles, although the exact number varies according to each patient.

Duration: From 1 to 5 weeks.

2. Egg capture


After the follicles have properly matured, the doctor extracts the eggs using an ultrasound-guided syringe.

Expected Result: On average, 3 out of 4 follicles will contain a mature egg.

Duration: Less than 60 minutes.

3. Fertilization


The eggs are combined with sperm in a laboratory to be fertilized. It can be through conventional insemination or the ICSI technique.

Expected result: Approximately 70% of the eggs captured will be fertilized.

Duration: Generally less than an hour.

4. Embryo development


Embryos are grown in conditions that simulate the body's natural environment.

Expected Result: Unfortunately, only 40% of fertilized eggs will develop properly for transfer.

Duration: Between 3 and 7 days.

5. Embryo transfer


The embryo is placed in the uterus. Some women choose to freeze them for later use, while others opt for immediate transfer.

6. Pregnancy test


A blood test is performed to determine if the embryo has been implanted correctly.

7. The beginning of a new chapter: Baby on the way

If the test is positive, congratulations! There is a high probability that in 36 weeks you will have a new member in your family.
