What is vitrification? What are its advantages?
Who can benefit from vitrification?Science makes giant strides, what seemed nearly impossible only a few years ago is a reality today. The efficiency of the technique allows various groups of women to take advantage of its implantation:
Step by stepThe process is the same as that of an In Vitro Fertilisation treatment. The first step is the hormonal stimulation of the ovaries (for 2 weeks approximately) up until the day of the follicular puncture, when the egg extraction is performed. Then, the oocytes are vitrificated in the laboratory and preserved in liquid nitrogen at -196ºC indefinitely so that the passage of time does not affect their reproductive potential.
As simple as possibleYour time is gold, and that of your eggs even more valuable. For this reason, once the decision to vitrificate your eggs is made, you will be able to do it immediately. At Girexx, we want to make it very easy for you, avoiding unnecessary visits to the clinic. For this reason, we have concentrated the treatment in just two appointments:
- Complete gynaecological examination.
- Assessment of patient’s personal and family medical history.
- Analysis of required medical tests results.
- Detailed explanation of the vitrification process.
- Information about the hormonal treatment and its ultrasound monitoring.
2nd visit ( two weeks later )
- Egg extraction, through a process called follicular puncture.
- Egg vitrification.
FREQUENTLY ASKED QUESTIONS
What is the best age to have my oocytes frozen?At 35 years of age the oocyte quality of a woman starts diminishing significantly, making it very difficult for a woman in her 40’s or older to get a pregnancy spontaneously. For this reason if you are between 30 and 40 and for various reasons you are not thinking of becoming a mother in the near future, you can have your oocytes frozen to preserve them from the passage of time and keep your fertility intact.
Does it have side effects?NO. It is not true that egg extraction can entail risks to develop cancer or increase the patients’s body weight. It does not trigger acne either. Egg extraction has no unwanted side effects.
Will I have an earlier menopause because of this?NO. In normal conditions, a young woman in her reproductive age (18-35) has a reserve of 200.000 to 300.000 ova (eggs). In every ovarian cycle (every 28 days) an average of 100 to 200 ova are released but only 1 or 2 of them ripen, the others deteriorate and are disposed of in the menstruation. Thus, in a stimulation process, we “make use” of a few eggs that would degenerate and be lost anyway by making them ripen but without altering the woman’s total number of eggs. These eggs are then frozen.
Will I be able to have children spontaneously after vitrification?SI. The ovarian stimulation process and subsequent vitrification of oocytes does not affect your ovarian reserve, in other words, your total number of eggs does not decrease. The vitrificated oocytes are simply a sort of “pregnancy insurance” in case you encounter some difficulties when you decide to become a mother.
Is it a painful process? Will I be able to lead a normal life?It is not a painful process.However, due to the treatment a slight increase of the patient’s body volume can be temporarily observed as a consequence of fluid retention, but this is similar to that during a menstruation. This is a totally normal symptom and it disappears when the treatment is suspended, a few days after the menstruation.
How long can my eggs be frozen?Liquid nitrogen allows us to keep the oocytes at -196ºC indefinitely, until you need them. Their reproductive potential is not affected by the passage of time.
What will I have to do when I want to use my frozen oocytes?When you decide to use your frozen oocytes, they will first be thawed, then inseminated and finally transferred into your uterus.
Is it a safe technique? Has it got unwanted side effects for the newborn?Despite being a pioneering technique of recent implantation, we have access to data that suggest that babies born from frozen oocytes are not exposed to a higher risk of illness than the rest of the population.
What’s the success rate? What’s the pregnancy rate after freezing my oocytes?It depends on various factors, especially on the number and quality of the oocytes when they are frozen but in general terms it is a very efficient technique and the chances to get a pregnancy are very high.
