Cryopreservation (Freezing)

If you are looking to conceive at a later date, or are intending to undergo medical treatment that could affect your fertility, cryopreservation is a way of preserving your healthy eggs/sperm/embryo to be used for pregnancy later on. Before participating in any method of cryopreservation, you will need to participate in blood studies and other forms of investigations.

Dr Ismail was interviewed on BBC Arabic in 2018 about fertility preservation. Find the video on our YouTube channel here.

Sperm Freezing

Reasons for sperm freezing:

  • If you are undergoing fertility treatment, so that you have a sample readily available if you are unable to produce a sample on the day of egg collection
  • If you are planning to have a vasectomy
  • Before undergoing cancer treatment which may affect your future fertility
  • As part of surgical retrieval of sperm from the epididymis (PESA) or testes (TESA)

The initial storage period is 1 year or, in cases such as pre-chemotherapy, it will be stored for 10 years.

Ovarian Tissue Freezing

This is a very successful method of fertility preservation, significantly more so than egg freezing. Queen’s Clinic are proud to be one of a very elite number of fertility clinics globally who currently offer the service.

This procedure involves removing the outer ovarian layer from your body during laparoscopic surgery, which contains a large number of immature eggs that can be grown and developed using various fertility treatments. This can be hundreds of eggs, compared to only about 10 using egg freezing! In most cases only part of the ovary will be removed, but we may decide that it will be more effective for you to preserve the whole ovary.

This is often recommended to women who are intending to undergo cancer treatments and women with early signs of ovarian cancer.

This treatment is relatively new, but it is already proving to be very successful and we are confident in this procedure.

ICSI (Intracytoplasmic Sperm Injection)

ICSI is used if your sperm sample quality/quantity is very low and failed to benefit from previous medical treatments. It involves injecting a single sperm cell directly into the egg, to give a much greater chance of successful development. ICSI is recommended if:

  • There is a severe problem with your sperm’s quality
  • Your sperm was surgically retrieved
  • Previous IVF treatment resulted in none or very few of the eggs being fertilized

Approximately 70% of eggs fertilized using ICSI will successfully result in a pregnancy, making it just as successful as IVF.
