Natural Modified IVF | Natural IVF

Natural Modified IVF (also known as Natural Cycle Modified IVF) is a form of Natural Cycle IVF. The treatment is carried out within your natural menstrual cycle – like Natural IVF – but is modified by introducing additional medication. Natural Modified IVF has an improved success rate compared with Natural Cycle IVF while retaining many of the benefits.


We are especially proud of our success rates for women with very low egg reserve, those in older age groups, and poor responders to high stimulation drugs using Natural Modified IVF.

What is Natural Modified IVF?

 

Natural Modified IVF involves egg collection within a woman’s menstrual cycle. Like Natural Cycle IVF, the focus is on collecting one high quality egg that has been naturally selected by the body, although sometimes more than one egg can be collected.

Natural Modified IVF differs to Natural IVF as during this process, medication is given for 3-4 days in order to block spontaneous ovulation (prior to egg collection), and a small dose of stimulation hormone is given to support embryo implantation, and so keep the follicles healthy and growing. For women who want to avoid injections, we can tailor the Natural Modified IVF cycle using tablets.

Who is Natural Modified IVF suitable for?

All women who ovulate are suitable for Modified Natural IVF treatment. In particular:

  • Patients with low egg reserve whose blood tests have indicated that they have low levels of Anti-Müllerian Hormone (AMH) or high levels of Follicle Stimulating Hormone (FSH)
  • Patients with low antral follicle count in their ovaries
  • Couples/women who have had previous failure of implantation with conventional IVF
  • Women who have produced fewer than three eggs with conventional stimulation (poor responders)
  • Those who want to avoid the risks and side effects of high stimulation. For example, those who have a strong family history of ovarian cancer and other oestrogen dependent tumours

The Procedure (2 weeks)

Initial Scan & Consultation

Come into the clinic at any time of the month for this appointment. This will include an Advanced Ultrasound Scan and consultation with one of our doctors where you will receive a personalised plan designed to give you the best chance of success.

Treatment Consultation

2 weeks before the start of your period you will come in to meet with a fertility nurse who will talk you through your treatment plan and go through the consent forms with you.

Scans & Blood tests

You will have 2 or 3 monitoring scans usually spaced days apart; each takes 20 minutes. The doctor may perform blood tests at these appointments.

Egg collection

This procedure is performed in the theatre under sedation and takes around 45 minutes.

Embryo Transfer

The embryo tranfer is a quick and easy procedure which does not need sedation and feels similar to a smear test

Pregnancy test

We will invite you back to the clinic for a pregnancy blood test and give you the test results by the end of the day.

Book an Initial Scan and Consultation What to expect

“'I was 31 years old when I was diagnosed with breast cancer. Everything had to be put on hold for such a long time for us, so it was amazing to see a positive pregnancy after my first cycle.'”

When I came in to CREATE for my first consultation and scan with the doctor, I could tell straight away he knew what he was talking about. He had done research into my cancer prior to seeing me and created a protocol for Natural Modified IVF with minimal drugs so that the treatment affected my hormones as little as possible. I honestly do not think any other clinic would have paid that level of attention to my specific needs.
