In Vitro Fertilisation (IVF)

In vitro fertilisation (IVF) is a well-established assisted reproduction treatment in which an egg is fertilised by sperm within a laboratory to create an embryo, which can then be transferred back into the uterus to implant.

What is IVF?

When is it recommended?

Using semen from a male partner

In vitro fertilisation using semen from a male partner is recommended for:

  • Couples for whom less complex treatments, such as intrauterine insemination (IUI), have failed
  • Women with an absence of, or lesions on, the fallopian tubes. These are important for natural fertilisation or artificial insemination
  • Women suffering from an advanced or severe cases of endometriosis
  • Women of advanced maternal age, where fewer oocytes are available
  • Couples experiencing male factor infertility, such as poor sperm quality
Using semen from a donor

In vitro fertilisation using semen from a donor is recommended for:

  • Couples experiencing severe male factor infertility
  • Couples for whom fertilisation has previously failed using the male partner’s sperm
  • Couples who have previously had poor embryo quality or repeated implantation failure in which the main cause is suspected to be a male factor
  • Couples in which the male partner is a known carrier of a genetic disease which cannot be screened in embryos
  • Single women

IVI London is committed to delivering highly personalised care combined with cutting-edge treatments to help patients build their families safely and successfully. During your first visit, your consultant will discuss your medical history and advise which fertility treatments will be most effective given your specific circumstances. If you choose in vitro fertilisation (IVF), then we will create a treatment pathway for you which is as follows:

Ovarian stimulation

Ovarian stimulation

Depending on the chosen stimulation protocol, the treatment should take between 10 – 20 days and will require regular visits to the clinic. During this time, you may also be required to take specific medication to help prepare your body for the IVF treatment. Your medical team will indicate which medication is needed and the recommended dosage based on your unique requirements. This often involves a series of daily hormone injections, which are administered at home, to stimulate follicle growth. We track the follicle growth through frequent monitoring ultrasound scans and blood tests to assess serum levels in the blood.

Oocyte retrieval

What happens during an egg collection?

36 hours after the final hCG trigger injection, you will attend the clinic where you will meet with an anaesthetist who will put you under light sedation. Once you are sedated, the oocytes are retrieved using a tiny needle, which passes through the walls of the vagina and aspirates the fluid along with any oocytes from the follicles. The fluid is immediately examined by an embryologist who will separate the oocytes (eggs) and assess how many were able to be collected. You will then be allowed to rest in your own private room, where your medical team will monitor you carefully and provide hot drinks and other refreshments. Once you have fully recovered, you will meet with your consultant to discuss the results and next steps. Afterwards, you can be discharged. For most of our patients, this entire process takes no longer than a couple of hours.

Selecting embryos for transfer

The stage where embryos are graded is an extremely important part in the IVF process, and it plays an integral part in the success of the treatment and the birth of a healthy baby. The grading of an embryo corresponds with the probability it will be able to implant. All IVI clinics are equipped with the most advanced clinical embryology technology available, allowing our embryology teams to make the embryo selection accurately and continue to improve implantation and birth rates.
