FEMALE FERTILITY PRESERVATION
WHAT DOES THE EGG VITRIFICATION, PRESERVATION OF FEMALE FERTILITY INVOLVES?
The female fertility preservation is the process that allows all those women who have or want to delay their motherhood for social, personal or medical reasons, to freeze some of their eggs at a biologically optimal age in order to maintain the ability to have children in the future through Assisted Reproduction treatment.
The factor to be taken into account to understand this therapeutic option is that as the woman’s age advances, in a physiological way, the number and quality of the eggs decrease and we are faced with a society, which is becoming more and more frequent, that delays motherhood.
Planning for motherhood, a right for all women
In Embriogyn, we make available to all those women who want to preserve their fertility, the latest medical and technological advances to take the step forward, with the Eggs Vitrification
EFFECTS OF AGE ON NATURAL FEMALE FERTILITY
It is important to know that from 35-37 years old women start a stage that implies a decrease in the fertile potential, much more marked from 40 years old. At this age, the monthly probability of pregnancy of a healthy woman is only 5% (compared to 20% at age 30). With age, the eggs present more and more chromosomal alterations that make pregnancy difficult and increase the probability of abortion and/or genetic diseases in children.
These data are important when planning women’s maternity and being able to consider the option of preserving female fertility by vitrifying eggs (egg freezing), since the delay in the reproductive age implies reducing the possibilities of being a mother with her own eggs. Currently we are already finding that the vast majority of pregnancies in Assisted Reproduction of women over 42 years are with donor eggs, not with their own.

WHEN EGG VITRIFICATION IS RECOMMENDED?
- Patients at risk for loss of ovarian function: cancer patients undergoing treatment with chemo or radiation therapy, bone marrow transplants, autoimmune diseases requiring chemotherapy, or women at risk for repeated ovarian surgery, such as endometriosis.
- No medical indication: Women who decide to postpone their maternity for various reasons or because their economic or work circumstances demand it.
FERTILITY PRESERVATION TECHNIQUES
EGG VITRIFICATION STAGES
Egg extraction occurs after ovarian stimulation to obtain several eggs in the same menstrual cycle and is performed through a simple and quick surgical process called follicular puncture.
After this puncture, the eggs are frozen using the egg vitrification technique, which allows the mature eggs obtained to be cryopreserved in liquid nitrogen at -196º for as long as necessary. This technique allows very high survival rates of the eggs to be obtained, around 95%.
WHAT HAPPENS WHEN I DECIDE TO BECOME A MOTHER?
Once it is decided that the time has come to be a mother:
- The desired number of eggs is then thawed.
- We transfer the embryos into the mother’s uterus.
WHAT DOES THE TREATMENT INCLUDE?
- Hormone tests during the cycle
- Medical visits and hormonal stimulation controls
- Follicular puncture and anesthesia
- Eggs vitrification
