Fertility preservation

Patients may wish to preserve fertility for several reasons

  1. To delay child-bearing
  2. To allow treatment of a medical condition which may affect future fertility
  3. To allow storage of eggs, sperm or embryos prior to cancer treatment

For male patients

Freezing sperm is the most effective way of preserving fertility. This can be done on more than one occasion if time permits.

For female patients

Egg freezing and embryo freezing

Both of these techniques require a process similar to IVF treatment. Recent advances mean that shorter protocols may require approximately 10 days to 2 weeks from the start of your period to collecting eggs.
The eggs collected may then be frozen directly (vitrification) or alternatively fertilised with a partners or donor sperm before freezing (embryo freezing).
Egg freezing is a more experimental approach to fertility preservation with only a few livebirths in the UK. However this method may be suitable for those patients who are single or may not be in a long-term relationship at the time of diagnosis. Newer methods of freezing and thawing eggs mean that this technique is likely to be more successful in the future but currently success rates are approximately 8%.
We will discuss these treatment options with you at your consultation in more detail.
(If appropriate we may also need close communication with your oncology team before embarking upon any treatment to ensure that we do not in any way lessen the chances of your cancer treatment being successful)

Ovarian tissue freezing

Several small strips from the outside of one of the ovaries are removed by laparoscopy (key-hole surgery). This tissue containing immature eggs is then frozen until a suitable time after which it may be transplanted back (grafted) on to the ovary.  This is an experimental procedure with a few reported livebirths.

This form of treatment may be considered for those patients who need to commence cancer treatments without delay and may also be suitable for those patients for whom IVF carries other risks.

Surgical options

IVF Hammersmith holds close links with gynaecological surgical oncologists, specialists in the surgical treatment of cancers of the female reproductive system. Standard surgical treatments may lead to loss of fertility but in some carefully selected cases a more conservative approach may be possible preserving future fertility.) 

Egg donation and surrogacy

For those patients who may not want to consider or who are not suitable for the above options then egg donation, surrogacy or adoption may be options for having a child in the future.
