Sperm and embryo freezing (Cryostorage) /FET
Sperm and surplus embryos can be frozen and stored for use in future treatment cycles.
Talk to us about ways we can help to preserve your future fertility.
Examples of storage and preservation
- Oncofertility for cancer patients (see below)
- Sperm freezing and storage can performed as a back up to using fresh sperm, such as when a husband’s work commitments prevent him from being available to provide a fresh sample.
It also a useful backup technique for husbands who may find it difficult to produce a sample on the day of egg pick-up.
- After a stimulated ART cycle there may be surplus embryos. These can be cryopreserved and stored for use in a future cycle.
Fertility Preservation for Cancer Patients
Oncofertility is a term used to define the medical field that links the specialities of Oncology and Reproductive Health. At Coastal IVF we have consulted with local specialists to explore and expand the options for the reproductive future of patients going through cancer treatment.
Certain cancers and their treatments (e.g. Chemotherapy) have the potential to severely impair the function of the reproductive organs and to cause a complication of long term infertility. If you are in the reproductive age group, with a recently diagnosed cancer, there are procedures available here on the Sunshine Coast to help protect your fertility options for the years following treatment. These procedures have been designed to ensure they will not compromise your oncology management/ treatment.
We have listed some common questions below:
1) Will fertility preservation delay my cancer treatment?
There have been a few overseas studies about this. These studies demonstrate that fertility preservation does not cause a significant time delay, and more importantly the time involved has no recognised impact upon mortality or recurrence rate for cancer patients. The average time delay (of fertility preservation) reported prior to commencing oncology treatment is approxiamtely 14 days.
2) Will fertility preservation affect my prognosis?
Although numbers are not high, studies have indicated that the present method of fertility preservation have no observable differences which were clinically relevant in terms of recurrence rates of mortality.
The general acceptance is that fertility preservation should not alter long term prognosis for cancer patient survivors.
3) What are the chances of future fertility with/without fertility preservation?
While types of fertility treatment have significant differences in the effects on reproductive potential, most studies suggest that following chemotherapy, around 40% of female cancer survivors will develop treatment induced ovarian failure and therefore face infertility.
While fertility preservation is not a guarantee of a favourable outcome in the future, modern IVF pregnancy rates are high from a single IVF cycle – therefore significantly improving your chances of a future fertility option if fertility preservation with oocyte or embryo preservation is implemented.
4) Are there methods which can be implemented to reduce the impact upon my cancer treatment?
There are a number of modifications of standard IVF procedures which allow for immediate or very early start of an IVF cycle, thus significantly shortening the time interval for fertility preservation. Secondly, there are a number of drugs or modifications of IVF programs which protect you from any theoretical adverse risks of fertility preservation (eg. high oestradiol levels). The specifics of treatment will be individualised and will be discussed with you.
