Embryo, egg & sperm freezing

Cryopreservation of embryos, sperm, eggs and testes biopsies is done for various reasons. Some of the more common reasons are medical conditions that require treatment harmful towards reproduction. Sometimes it is due to logistical reasons or just to preserve fertility till the patient is ready to start with a family.

Is Cryopreservation (freezing) right for me?

Cryopreservation is the freezing and thawing of embryos for use in future IVF cycles. Sperm can also be frozen for men who are about to undergo surgery, chemotherapy or radiotherapy which could possibly impair their future fertility.

Fertility preservation

Women at risk of early menopause, have genetic disorder limiting fertility or wish to have children later can have eggs collected and stored.

Medical Conditions

Egg freezing has the potential to assist female cancer patients, as chemotherapy and radiation treatment can often have a harmful effect on fertility, rendering many of these patients menopausal.

Logistical reasons

Men who travel, serve in the military or who are undergoing vasectomy can benefit from sperm banking. Cancer treatment for males can also result in a decline in sperm quality, and often times even sterility.

Left over embryos

During an IVF cycle there may be some extra embryos created. These embryos can undergo cryopreservation and be used for future IVF cycles. In this way there is no need to induce ovulation a second time and thereby reduces costs.

Cryopreservation can be an excellent way to preserve your fertility and improve your chances of having a biological child in the future. 

The Egg-Freezing Process

Our centre uses vitrification when freezing eggs. In this process the solution containing the egg is cooled so rapidly that the water molecules do not have time to form damaging ice crystals and instantly solidify into a glass-like structure.

Evaluation of ovarian reserve

An appointment will need to be scheduled where the doctor will do blood tests as well as ultrasound evaluations of the ovaries. This is to check whether ovulation is occurring and also to check how many ova are available.

Ovulation induction

Daily injections with FSH (Menopur, Gonal F, Fostimon or Puregon) is given for 6 – 8 days and most women administer it themselves. This stimulates the growth of several follicles instead of just 1 or 2. The response of the ovaries is monitored with ultrasound and will vary according to each woman’s ovarian reserve.

Egg retrieval & freezing

Once your eggs are ready to be retrieved, you will undergo a quick 15-minute surgical procedure to retrieve the eggs. You will be sedated and the eggs will be removed with a needle through the vaginal wall – there are no cuts or stitches. Immediately after the retrieval, the eggs will be frozen in the lab.   


The eggs are stored at a facility and will be kept there until you notify us that you need them. An annual fee is payable to store the eggs.

Frozen Embryo Transfer Process

A frozen embryo transfer, or FET, is a kind of IVF treatment where a cryopreserved embryo created in a full IVF cycle is thawed and transferred to a woman’s uterus. The cryopreserved embryo may be from a woman’s previous conventional IVF cycle, or it may be a donor embryo.
