Egg & sperm freezing

Guide to Egg & Sperm freezing

Why should I freeze my eggs?

Fertility in women declines from the age of 35, and for women who are concerned about ensuring that they have an option of conceiving in the future, egg freezing offers a viable solution. The earlier eggs are frozen the better, as eggs are more numerous and healthy the younger you are. Egg freezing is suitable for anybody who wishes to preserve their fertility, whether because they wish to pursue a career, have not yet found the right partner or have medical reasons for doing so. We freeze eggs using vitrification or fast freezing, a technique pioneered by one of our Scientific Directors R C Chian.

What does egg freezing involve?                                                          

The process for freezing eggs is similar to that of undergoing full IVF, except that there is no embryo transfer at the end. You will need to come in for an initial consultation with one of our doctors who will assess your ovarian reserve and medical history and suggest the most suitable treatment. You will then take some medication to encourage the growth of the eggs and come into the clinic for scans to monitor their growth. At the end of a week or so, you will come in for your egg collection which will be carried out in the theatre under sedation. The eggs will be frozen following this and can be thawed if you decide to go ahead with any fertility treatment; the survival rate of eggs after thawing is 91%.

What are the success rates with egg freezing?

Around 91% of frozen eggs will survive the thawing process, and the success rates for fertility treatment using these eggs is comparable to treatment with fresh eggs. The age at which the egg was frozen is important in determining future success rates, as younger eggs are healthier. If around 15 eggs are frozen, there is around a 50% chance of having a baby with them in the future (for women under the age of 35).

Sperm freezing

Do you do sperm freezing?

Yes. Sperm freezing is a relatively simple process. Before having the sperm frozen you will need to have some screening bloods taken, for HIV, Hepatitis B Core Antibodies, Hepatitis B Surface Antigens and Hepatitis C. These can be done with your GP or we can perform them at the clinic for £150. You will then need to come into the clinic to fill in some forms produce a sample. Please abstain for 2-5 days before this. The sample will then be frozen by our embryologists using vitrification technology. It costs £150 to freeze sperm.
