Fertility Preservation

It consists of gametes (eggs or sperm) freezing to delay motherhood or fatherhood. It's addressed to women and men wanting to store their genetic material to use it in the future, for medical reason or other reasons.

Best techniques for female fertility preservation are egg freezing and embryo freezing. In both cases it's necessary to undergo previous ovarian stimulation and egg's retrieval through ovarian puncture.

Once eggs are obtained, those presenting good quality and being mature can be vitrified. In case of embryo vitrification, eggs are inseminated with the partner sperm and, subsequently, the obtained embryos are vitrified. Eggs or embryos are stored in liquid nitrogen at -196ºC until the woman wants to become mother.

Since quality and number of eggs in women are progressively decreasing as they get older, it's advisable to perform this technique when there is still an adequate ovarian reserve, that is, until the age of 35-38. The best moment is indeed before the age of 35, that is the moment of the best egg quality. At older ages, eggs might have a worst survival rate as well as more chromosome abnormalities; therefore pregnancy chances will be reduced.

Currently, factors like studies or work make many women delay childbearing. Thanks to the advances in cryopreservation techniques, these women can preserve their fertility through egg vitrification. They will be able to use them in the future to get pregnant, avoiding the fertility's decrease due to age and without renouncing to a pregnancy of their own genetic material.

Oncology treatments might seriously or irreversibly affect woman's fertility. In those cases information from a specialist and fast synchronization with the assisted reproduction centre allow patient to preserving her fertility without jeopardizing her pathology's treatment. Thanks to eggs vitrification we can offer these women the opportunity of achieving her dream of becoming mother once they got rid of disease.

This treatment would also be recommended to patients with endometriosis, family history of early menopause, autoimmune diseases or previous to ovarian surgery or gonadotoxic treatment.

Main medical indication for sperm freezing is when patient is going to receive oncology treatment that might affect his reproductive health. In those cases it's also crucial the celerity of action of the oncologist, who has to refer patient to assisted reproduction clinic, where he should freeze as many samples as possible before treatment starts.

Due to high incidence of testicular cancer among youngsters between the age of 15 and 35, it's very important to suggest them fertility preservation and make it possible for them, so they can enjoy paternity in the future.

There are other indications, not medical, such as freezing semen prior to vasectomy or during assisted reproduction treatment, should the patient not be available when requested or if he has difficulties in collecting the sample in a specific moment.
