Providing You with IVF in London

IVF, also called in-vitro fertilisation, was first developed over 40 years ago and has since become the most common and most effective type of fertility treatment. We can offer you IVF in London, if it’s decided that this will be the most beneficial treatment option for you. 

If you are interested in having this treatment and would like to know more about what it may involve, please read on. Or, if you’d prefer to speak to one of our consultants or coordinators as soon as possible, please do not hesitate to contact us right away. We’ll be glad to answer any questions you may have.

Our IVF Clinic in London, UK

The process begins with what we would call “ovarian stimulation”; this means giving the patient a hormone injection to stimulate their ovaries into producing multiple follicles, inside which the eggs develop. During this 9 to 14 days of stimulation your progress will be monitored by transvaginal monitoring scans and blood tests. Once follicles reach a size between 17 - 20mm you will be given a final injection of human chorionic gonadotropin (hCG) or gonadotropin releasing hormone agonist (GnRHa) - this is what we call the “trigger” injection. This will take place 35 to 36 hours before we carry out the egg collection.

Egg collection will be carried out under mild sedation anaesthesia and will take around 15 to 20 minutes. Once the eggs are retrieved by aspirating the follicles using a vaginal ultrasound probe, they will be mixed either with your partner’s sperm or with your selected donor sperm in a Petri dish in a controlled environment by our embryologists. 

The morning after this, our embryologists will assess the eggs for any microscopic signs of fertilisation. A fertilised egg cell will divide and grow from one cell, splitting into two, then four, then eight, and so on until embryologists will select a viable embryo to transfer back to the womb/uterus of the intended parent between three to five days after egg collection. Any good quality embryos that remain can then be cryopreserved (frozen) for future use.

14 days after the embryo transfer procedure, we will perform a blood or urine pregnancy test to see if the process has been successful.

Your Remaining Embryos

Often, several embryos will be created through the fertilisation of your eggs, and we understand that you may wonder what will be done with the embryos that are not yet in use. In these cases, it’s normally best practice to have these embryos frozen and preserved. This is the alternative to putting two embryos back in your womb, as this increases your chances of having twins or triplets. 

You will be able to use your frozen embryos in the future, in the event that your first cycle is unsuccessful, or if you decide that you’d like to try for another baby at a later date.

The Types of IVF Cycle

There are several types of IVF cycle available to you at our centre. When you speak with one of our specialists, they will be able to help you decide which is right for your journey to parenthood.

Stimulated Cycle IVF

Stimulated IVF, which is sometimes also known as Conventional IVF, is a common and often undertaken process for our patients. During this treatment, drugs will be used to obtain multiple eggs, which will then be used to create multiple embryos. This increases your chances of becoming pregnant. 

In a standard monthly reproductive cycle, a single egg will grow and mature inside an ovarian follicle. It will then be released and become viable for  fertilisation at a certain hormonal level. Stimulated Cycle IVF differs from this because the patient will take fertility medication to stimulate the ovaries. In turn, this ensures the growth and maturity of multiple egg follicles. These will be monitored by a specialist clinician with ultrasounds and bloodwork to track the follicle growth.

An egg retrieval procedure (also called egg collection) will be performed once the follicles have reached a certain size. This will be done under anaesthesia, and the retrieved eggs will then be mixed with sperm collected either from the patient’s partner or their selected donor.

The resulting embryos will be allowed to grow until the embryologist can identify the ones that will be most suitable for transferring back into the patient’s uterus. Any excess embryos may also be frozen and stored for future use.

Mild IVF

A similar form of fertility treatment to Stimulation or Conventional IVF is Mild IVF, also known as Mild Stimulation IVF. Much like the former variety, Mild IVF uses stimulating drugs to collect between 2 and 10 eggs for fertilisation. However, these drugs are given at a lower dosage to decrease the risk of over response (Ovarian Hyperstimulation Syndrome, known as OHSS).

Natural Cycle IVF

Unlike Stimulation IVF and Mild IVF, Natural IVF uses no drugs or medication to stimulate the growth of follicles. Instead, it follows the natural selection of the follicle. 

The patient’s body will naturally select the best egg available for the cycle. When this egg is mature (around the 10th to 12th day of your cycle), we will collect it in a straightforward process of ultrasound guided egg collection. Many of our patients are able to complete the procedure without the need for sedation or pain relief, and can even return to work the same day if they feel up to it.

The eggs taken will then be fertilised by sperm collected from the patient’s partner or their chosen donor. Two to three days after this, we will transfer a single embryo into the patient’s uterus. We will test for pregnancy two weeks after this, with the entire process being based on your menstrual cycle. There will be little to no drug use and only a very low chance of multiple pregnancy.

There is a high cancellation rate in Natural Cycle IVF due to a failure of follicular growth or premature ovulation, unfortunately.

Why Many Patients Opt for Natural IVF in the UK

Many of our patients prefer to receive Natural IVF over Stimulated or Conventional IVF, owing to the fact that it is often more affordable and minimises levels of discomfort. There are also cases in which the success rates associated with Natural IVF are predicted to be the same as Stimulated IVF. In these cases, we would recommend Natural IVF as the patient’s treatment of choice at our centre.

Some advantages which often make Natural IVF the best treatment type for our patients include:

  • Minimal or no use of ovarian stimulation drugs
  • The procedure is often considered less stressful
  • It is often more affordable
  • It can be repeated with back-to-back cycles
  • There is no risk of Ovarian Hyperstimulation Syndrome (OHSS)
  • Cumulative pregnancy rates may be similar to Stimulated IVF

To be able to receive IVF at our London treatment centre, candidates may be over 40 but should ideally be under the age of 46 (this is unlike NHS hospitals and clinics). They should also have regular menstrual cycles, a normal uterus and no medical contraindications.

Natural IVF has been found to be ideal for patients who have:

  • A low ovarian reserve
  • No or a poor response to Conventional IVF
  • Previous unsuccessful Conventional IVF treatments
  • Male factor subfertility
  • Tubal occlusion
  • Endometriosis

Our Philosophy on Stimulated and Natural Cycle IVF

At GENNET City Fertility, we believe in an individualised approach to your fertility challenges and a bespoke fertility treatment plan. Natural Cycle IVF is certainly one of many treatment options that we will discuss with you, and there are many patients who have failed or are not candidates for Stimulated IVF. Nevertheless, they have achieved a successful pregnancy using Natural Cycle IVF. Some were even told that their only option for pregnancy was through egg donation or adoption. 

Some experts now recommend that patients consider Natural IVF prior to undergoing egg donation or adoption (Kadoch et al., 2011, Fertility/Sterility).

Frequently Asked Questions

What About the Natural Cycle IVF Pregnancy Rates?

The concern with Natural Cycle IVF has focused on the lower success rates and the need for multiple treatment cycles to achieve the same pregnancy rates as a single treatment cycle of stimulated IVF. Current medical literature contains many reports showing acceptable clinical pregnancy rates using Natural Cycle IVF ranging from 15-25% per embryo transfer. This includes patients who are known to be “poor responders” to stimulatory drugs.

What is Egg Sharing IVF in London?

Egg sharing IVF is a process in which a patient currently receiving IVF treatment elects to donate half their eggs to someone who cannot use their own, or is unable to produce their own. Egg sharing is normally carried out by NHS hospitals and fertility clinics. In return, the patient providing the eggs will receive their treatment at a reduced cost.

How Likely Are You to Get Pregnant From IVF if You’re Over 40?

NHS hospital studies have shown that patients over the age of 40 have around a 9% chance of success at getting pregnant from IVF. However, it must also be noted that a patients’ chances of successful IVF treatment depend on their own individual circumstances, as well as their age groups. As such, we will be more than willing to help you proceed with IVF treatment if you are over 40, but under the age of 46.
