There are a multitude of options when it comes to preserving fertility in both men and women when it comes to cancer and cancer treatments. We have listed some of the more popular and successful options below. However, each situation is different and it is always best to consult with your doctors on what is the most appropriate treatment plan for you.
Embryo Freezing – Embryo freezing or cryopreservation allows a patient to store embryos for future use. The first step of embryo freezing involves stimulating the ovaries to provide multiple mature multiple eggs. Doctors then remove the mature eggs and fertilize them in the lab with sperm from a partner donor to create embryos. This process is called in vitro fertilization (IVF). Embryos are then frozen and stored for future use.
Egg Freezing – Egg freezing is a process where a woman’s eggs are extracted, frozen, and then thawed for later use. The first step of Coastal Fertility Egg Freezing involves stimulating the ovaries to provide multiple mature multiple eggs. Doctors then extract the eggs and freeze them for future use.
Sperm Banking – Sperm banking can often be an effective way to preserve fertility in men. No procedures are required as the man can simply collect his own semen sample and store it at a sperm bank. Tests can be done to ensure the quality of the sample.
In cases where more eggs develop into embryos than are going to be transferred to the patient, the couple will have the option of cryopreservation, or freezing, of the embryos for transfer into the woman’s uterus at a later date.
Cryopreservation is used to minimize the risk of multiple births, which increases dramatically if more than four or five embryos are replaced. Once embryos are frozen in liquid nitrogen and stored, viability will remain unchanged for long periods. With current freezing and storage methods, 60 to 80 percent of embryos will be viable after thawing. One of the advantages of embryo cryopreservation is that transfer of the thawed embryo may occur in a natural ovulatory cycle.
