Natural Cycle IVF

Natural Cycle IVF is a fertility treatment that involves collecting just one egg from the ovary without using additional hormonal stimulation. This process includes an initial examination of the woman, hormonal blood tests, and ultrasound to monitor the gradual development of the follicle throughout the cycle.

The procedure of Natural Cycle IVF

When the follicle reaches the appropriate size, a dose of HCG is administered to enhance egg maturation. The egg is then collected 36 hours later, typically between the 12th and 14th day of the cycle (depending on the woman’s cycle), using local anaesthesia or sedation. Following egg retrieval, fertilisation with sperm occurs. The resulting embryo is transferred to the future mother’s uterus after 3 to 5 days.

Advantages of Natural Cycle IVF

Natural Cycle IVF offers several benefits, including:

  • No medication required: No additional hormonal treatments are necessary.
  • Simple and safe process: The procedure is straightforward and generally safe.
  • Can be performed in each cycle without waiting: Treatment can be conducted in consecutive cycles without delays.
  • Reduced risk of ovarian hyperstimulation syndrome: There is a lower chance of developing this condition.
  • Reduced chances of multiples: The likelihood of twins or triplets is minimised.
  • Lower cost: This method is typically less expensive than stimulated IVF cycles.

Suitability for Natural Cycle IVF

Natural Cycle IVF is particularly suitable for women who:

  • Are older and do not respond to stimulation drugs: Older women who may not benefit from hormonal stimulation.
  • Are contraindicated for hormone therapy: Women who should not use hormonal treatments.
  • Have elevated FSH hormone levels: Women with high FSH levels who may not respond well to stimulation.
  • Do not want to produce many eggs and embryos for ethical reasons: Those preferring a more controlled approach.
  • Want a more natural approach: Women seeking a less invasive fertility treatment.

Effectiveness and Success Rates

The effectiveness of Natural Cycle IVF shows satisfactory success rates, although they are generally lower compared to IVF with ovarian stimulation. Despite this, it provides a viable option for those seeking a natural fertility treatment method.
