Egg freezing

Egg freezing

The quality of a woman’s eggs decreases with age and, this decline is even more dramatic from the age of 35 onwards. This leads to a progressive and continuous reduction in the likelihood of getting pregnant, as well as the likelihood of having a healthy pregnancy. Egg freezing gives the woman the possibility of becoming a mother at a later stage in life because when eggs are frozen or vitrify, they maintain the quality they had at the moment of vitrification (freezing). Younger eggs are more likely to achieve pregnancy.

Reasons for fertility preservation

Age: With age, fertility naturally decreases. If you freeze your eggs, you are able to stop your eggs’ biological clock, preserving your fertility and increasing your chance of pregnancy in the future.

Your genes: Whenever you are ready to become a mother, if you require assisted reproduction techniques in order to do so, your frozen eggs will have preserved their quality and you can ensure using your own genetic material, as opposed to that of a donor.

Is this technique safe?

It is important to know that the quality of the eggs when frozen, will condition the possibilities of success after thawing.
We know that if a woman is under 35 when she freezes her eggs, about 10-12 vitrified eggs will give her a 60% chance of pregnancy. After 35, this percentage drops.

In accordance with the ovarian reserve and the expectations of each patient, our specialists will recommend the number of eggs to freeze and an estimate of the number of cycles required in order to freeze the desired number of eggs.

Egg Freezing Process

To stimulate the ovaries, the patient must give herself hormone shots every day to obtain the number of eggs that mature during the cycle. This stimulation will be monitored by ultrasound in order to adjust the medication and program the egg retrieval at the optimal time.

Egg retrieval is an easy procedure that is performed by the vaginal route and under sedation. It takes about 15-20 minutes. After the procedure, the patient easily wakes up without any secondary effects.

After the egg retrieval, the biologists will check and see if the eggs obtained are mature. All the mature eggs will be vitrified and conserved in the laboratory. The egg quality will remain intact until the woman decides to use them.

Reasons for egg vitrification

  • Social Reasons: when a woman, voluntarily, decides to postpone her maternity, she may consider saving her oocytes at the present moment in order to use them in the future. This usually happens in cases when the patient has yet to find the right partner, or when she decides to focus on her professional career and postpone her maternity.
  • Medical Reasons: in cases where patients have to undergo aggressive medical treatments (that cause gonadal toxicity), which could compromise their future maternity.  For this reason, patients who have to undergo radio or chemotherapy, aggressive ovarian surgery, patients with severe endometriosis or those who will undergo cytotoxic treatments because of autoimmune diseases, can benefit from freezing their eggs prior to undergoing any of these procedures.

When the woman decides to get pregnant, the eggs will be fertilized using either her partner’s sperm or donor sperm in order to obtain embryos.

If the woman gets pregnant spontaneously and does not want to use her frozen eggs, she can donate them to other women, as long as they were frozen prior to her turning 35 years of age.
