Scientists promote childbearing during the most fertile years (under 35), but if you are not ready to become pregnant at this stage of your life, cryopreservation may be of interest to you.
Scientists promote childbearing during the most fertile years (under 35), but if you are not ready to become pregnant at this stage of your life, cryopreservation may be of interest to you. If you have to postpone childbearing due to your lifestyle, educational opportunities or career choices, you should be aware that the ovarian reserve decreases with age.
Why consider egg freezing?
If you are between age 30-35 and you are not ready to become pregnant, Oocyte /Egg Cryopreservation may be of interest to you.
If at this time of your life you have not met the partner with whom you would like to share your life or you have career commitments which make it difficult to consider childbearing, oocyte cryopreservation may be suitable for you.
Oocyte cryopreservation is also to be considered if you must undergo chemo/radiotherapy since these treatments often destroy oocytes leading to infertility.
Scientists do promote childbearing during your most fertile years (under 35) but if this is not possible for you, then oocyte freezing may be suitable.
Progressive loss of oocytes is a normal process. A female infant is born with 1-2 million oocytes and by the age of 37 this number falls to 25000 .
The decrease of oocyte quality in women >37.0 of age is correlated with high risk of genetic abnormalities in the embryo.
Is that safe?
- No risk to the child or mother
Several scientific studies have confirmed that there is NO evidence for increased health/ genetic risks, adverse obstetric or perinatal events when using cryopreserved oocytes.
- An established procedure
Clinical trials evaluating the effectiveness of oocyte cryo-banking have demonstrated comparable success rates of ongoing pregnancies obtained with fresh versus frozen eggs
In addition, the American Society of Human Reproduction has recently approved vitrification of oocytes as a routine method in embryology labs.
- No significant oocyte loss
Scientific advances have optimized the oocyte freezing protocol to yield oocyte survival rates of more than 90%
- Storage time
The standard storage period for eggs is normally 10 years. This period can be exceeded only in certain circumstances.
- A woman is prepared for oocyte retrieval, as in routine IVF (in vitro fertilization), by controlled ovarian stimulation under medical supervision.
- Collected oocytes are vitrified and stored in the embryology lab under controlled storage conditions. When oocytes are needed, they are warmed, fertilized and transferred to the uterine as embryos.
