WHAT IS AN EGG RETRIEVAL?

puncion ovarica

It is normal that many questions arise when undergoing assisted reproduction treatment. A couple of the most frequently asked questions are: What is egg retrieval? And, will it be painful? At Ovoclinic we want to dispel the false myths surrounding this procedure, explain what this important process is and how it allows you to achieve your dreams of becoming pregnant.

THE EGG RETRIEVAL PROCEDURE: THE WHY, HOW AND WHAT TO EXPECT

This simple procedure is performed under sedation and involves using a fine needle to puncture the ovarian follicles and obtain the eggs needed to begin an IVF treatment. In a matter of minutes, we can have all the eggs that we will use in the in vitro fertilization process (IVF). Additionally, an egg retrieval procedure is also necessary if a patient wishes to freeze her eggs for fertility preservation.

HOW IS AN EGG RETRIEVAL PERFORMED?

The egg retrieval should be carried out before ovulation occurs, so the development of the ovarian follicles is closely monitored until they reach between 16 and 18mm when they are ready for the procedure. In each cycle, between 6 and 9 eggs are usually obtained, depending on the patient’s individual characteristics. It is important to bear in mind that not all the follicles counted before puncture contain eggs, and not all eggs that are retrieved are of sufficient quality or in the right stage of maturation to be used for fertilization.

Below is our guide to the steps involved in egg retrieval.

BEFORE THE EGG RETRIEVAL

A woman usually ovulates only one egg per month, after it has gradually matured in its follicle. Therefore, in order to increase the number of egg cells we can obtain, we need to stimulate the ovaries so that more follicles mature than would occur naturally.

  • Controlled ovarian stimulation: this is done by administering hormonal medication over the course of one or two weeks. Thanks to this technique, the number of developing eggs increases to between 8 and 10. The Ovoclinic medical team will monitor and control this step closely so that it yields excellent results.
  • Monitoring from the beginning of the cycle: during the ovarian stimulation process, a series of ultrasound examinations are performed starting at the beginning of the cycle to ensure the follicles are developing to the required size
  • Administer HCG hormone: this hormone triggers the final step of egg development and ovulation would typically be after 36 and 48 hours, giving us the window for egg retrieval.

Below is our guide to the steps involved in egg retrieval.

THE STEPS OF THE EGG RETRIEVAL PROCEDURE

Once the controlled ovarian stimulation has been completed successfully, the patient is ready for the procedure to begin.

On the day of the procedure, the patient should:

  • Arrive 30 minutes beforehand
  • Come in a fasted state
  • Be as relaxed as possible

Ovarian puncture::

During this procedure we will use a transvaginal ultrasound to visualize the follicles, and a fine needle to extract the eggs by aspiration. The egg cells are then separated from the follicular fluid and deposited in their Petri dishes.

Laboratory analysis::

In the laboratory the results are carefully analyzed, and immature eggs that are not suitable for fertilization are discarded.

RECUPERATION AFTER THE PROCEDURE

After the egg retrieval, the patient will remain under observation in the recuperation room and the effects of the sedation will gradually disappear. When everything is in order, she can go home.

We recommended avoiding strenuous activity in the 24 hours following the procedure as light vaginal bleeding may occur.
