Modified Natural Cycle IVF

Mr Hany Mostafa is proud to be the 1st clinician in the North East to start offering Modified Natural Cycle IVF as an additional option to his patients.

Modified Natural Cycle IVF is a type of Natural Cycle IVF that involves the use of minimal ovarian stimulation with tablets and small doses of injections.

Read these documents for information on the differences between Natural Cycle and Modified Natural Cycle IVF.

The success rates of Natural IVF treatments may be lower compared to conventional stimulated IVF, but the treatments are safer, less expensive and can be repeated in subsequent cycles, meaning there is no need to have a break between treatment cycles.

Why choose Natural Cycle IVF?

  1. Natural Cycle IVF is a less invasive approach where the use of minimal stimulation drugs leads to fewer risks and side effects.
  2. In conventional IVF treatments, the patient takes drugs to force both ovaries to produce multiple eggs, which can lead to multiple pregnancies. The treatment cycle may also be prolonged by nearly two weeks due to suppression of the ovaries – leading to unpleasant menopausal symptoms.
  3. The potential risks with stimulated IVF also include ovarian hyper-stimulation syndrome (OHSS), adverse conditions in the lining of the womb for embryo implantation and an increase in chromosome abnormalities in both eggs and embryo.
  4. Natural Cycle IVF avoids side-effects such as headaches, hot flushes, bloating, mood changes or other concerns relating to ovarian stimulation.
  5. Natural Cycle IVF is less expensive than stimulated IVF treatments as it does not require daily doses of the costly medications.
  6. Natural Cycle IVF patients can repeat their treatment in consecutive cycles – whereas, due to the effect of ovarian stimulation drugs on the body, stimulated IVF patients need to take 2-3 months break between cycles.

What is the Natural Cycle IVF procedure?

The procedure involves the collection of a naturally produced egg by a simple minor procedure. The eggs will be fertilized in the laboratory with the partner sperms, and the developing embryos will subsequently be replaced into the uterus which has not been stimulated by medication.

What is the success rate for natural cycle IVF?

The success rate of natural cycle IVF in patients with adequate ovarian reserve is generally good and comparable to conventional IVF treatment. The success rate in patients with reduced ovarian reserve is generally low (around 8 – 10% in different studies), meaning that 8 – 10 women out of one hundred will get pregnant in a natural cycle. The lower success rate is linked to the nature of the patients receiving treatment and the lower likelihood of obtaining an egg in each cycle.
