PRESERVING MALE FERTILITY
Freezing and thawing sperm has very good survival rates for sperm mobility and sperm fertilization. Also, cryopreservation of sperm isn’t related to the development of congenital or other embryonic abnormalities.
Sperm freezing is recommended to:
• Male patients with previous medical history of oligoasthenospermia
• Men with exposure to chemicals, radiation or excessive heat that can cause infertility
• Men to be subjected to surgery (prostate or testicular surgery)
• Adult men or teenagers who are going to undergo any treatment that may affect their reproductive capacity
• Adult men or teenagers who are about to undergo a cancer therapy (surgery, chemotherapy and radiation)
PRESERVING FEMALE FERTILITY
The most common methods of preserving female fertility are:
As a method embryo cryopreservation is addressed to women:
• With health problems and who are going to undergo treatments that cause damage to the ovary and may/wish to freeze embryos instead of freezing eggs
• Who are subjected to IVF and exhibit inappropriate endometrial function (e.g. with high hormone levels)
IS THE EGG FREEZING SAFE?
The egg is the largest human cell and consists mainly of water and when it is cooled it forms crystals that can destroy it.
WHAT IS THE BEST AGE FOR EGG CRYOPRESERVATION?
The age at which a woman should choose this technique depends on many factors and is mainly related to the reasons why a woman wants to prolong her fertility.
As a method, egg cryopreservation is addressed to women:
• Who have health problems and are about to undergo treatments that cause damage to their ovaries and their eggs (ovarian ablation, chemotherapy or radiation therapy in cases of cancer)
• Who have a family history of premature menopause
• Who want to prolong their fertility for the distant future for educational, professional, economic or purely personal reasons
