Natural Modified 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 IVF while retaining many of the benefits.
We are especially proud of our success rates for women with low egg reserve and those in older age groups 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 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 IVF (poor responders)
- Those who want to reduce the risks and side effects associated with conventional IVF.
The Natural Modified IVF process
Initial Consultation & Scan
The first step is for you to come in for an Initial Consultation & scan where one of our IVF Consultants will assess you and devise a personalised treatment plan which will give you the best chance of success.
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.
This procedure is performed in the theatre under sedation and takes around 45 minutes.
The embryo transfer is a quick and easy procedure which does not need sedation and feels similar to a smear 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.
