What Is IVF: A Simple Breakdown

What is IVF?

IVF stands for in vitro fertilisation, which literally means fertilisation that happens outside the body. This is achieved during a medical process in which an egg is fertilised with sperm in a laboratory and the resulting embryo is placed into the uterus to hopefully implant and become a pregnancy.

During IVF:

  • Eggs are collected from the ovaries
  • The eggs are fertilised with sperm in a laboratory
  • The resulting embryo is transferred into the uterus

Today, more than 4 decades since the first IVF baby was born, IVF remains a mainstream medical treatment used worldwide, with an impressive safety record and success rates.

Because fertilisation happens in a laboratory, IVF babies were once commonly called “test-tube babies”. But for many families, IVF represents hope.

Parents often describe children born through IVF as miracles or dreams come true, not because the science is mysterious, but because the outcome is deeply meaningful.
 

A brief history of IVF

IVF is not new. It is the result of decades of careful research, dedication and scientific persistence.

The IVF procedure was pioneered in the United Kingdom in 1978 by Sir Robert Edwards, together with embryologist Jean Purdy and gynaecologist Patrick Steptoe.

As early as 1958, Sir Robert recognised that fertilisation outside the body could help treat infertility. At the time, this idea faced strong criticism from religious leaders, ethicists and even parts of the medical community.

Despite years of obstacles and moments where the team nearly gave up, they continued their work, encouraged by letters from couples who desperately wanted children.

On 25 July 1978, the world’s first IVF baby, Louise Brown, was born. Since then, an estimated eight million babies have been born through IVF treatment worldwide.

Sir Robert Edwards later received the Nobel Prize in Physiology or Medicine for his work, recognising IVF as one of the most important medical advances in reproductive health.
 

Who IVF is designed to help

IVF is a type of assisted reproductive technology used to treat fertility problems that make natural conception difficult or impossible.

IVF may be recommended when:

  • Eggs and sperm are unable to meet naturally
  • Fertilisation cannot occur inside the body
  • Previous fertility treatments have not been successful
  • There are genetic or fertility challenges that require laboratory support

IVF is not a single solution for everyone. It is one option among many fertility treatments. The key is understanding whether it fits your individual circumstances.
 

IVF Explained Simply: How The Process Works

IVF may sound complex, but the concept itself is straightforward.

An egg is fertilised with sperm in a laboratory.

The embryo is placed into the uterus.

If implantation occurs, pregnancy begins.

What many people do not realise is that IVF is not one procedure. It is a series of carefully timed steps that usually take place over about 28 days.

From the first day of your cycle to the pregnancy test, each stage is designed to maximise your chance of success.

Stage 1: Preparing the body for IVF

IVF treatment usually begins on day one to three of your menstrual cycle.

The first stage involves medication to:

  • Stimulate the ovaries so multiple eggs can develop
  • Prevent ovulation from happening too early

These medications may be tablets or injections. Because hormone levels are changing, some women experience side effects, which is why careful monitoring is essential.

Monitoring typically includes:

  • Blood tests
  • Ultrasound scans starting around day eight
  • Follow-up scans on days ten and twelve

This monitoring allows the fertility team to adjust treatment and ensure the ovaries respond safely and effectively.

Stage 2: Egg collection

Once the eggs are ready, an injection of HCG is given about 36 hours before egg collection.

Egg collection:

  • Takes about two hours
  • Is performed under sedation
  • Uses a fine needle guided by ultrasound

After egg collection, progesterone is given to prepare the lining of the uterus for embryo transfer.

Stage 3: Fertilisation

On the same day as the egg collection:

  • A sperm sample from the male partner or a donor is prepared
  • Eggs are fertilised in the laboratory

This is where IVF truly happens.

Stage 4: Embryo development and selection

After fertilisation, embryos are grown in the laboratory for three to five days.

Thanks to advances in embryo culture:

  • Embryos can develop to the blastocyst stage on day five
  • Higher quality embryos can be selected for transfer

Any additional good-quality embryos are frozen and stored in liquid nitrogen. These frozen embryos can be used in future treatment cycles without repeating egg collection.

Stage 5: Embryo transfer and implantation

Embryo transfer is a simple and painless procedure.

  • No anaesthetic is required
  • An ultrasound guides placement into the uterus

After transfer:

  • The embryo may take six to seven days to implant
  • Medication may continue to support the uterine lining

Stage 6: Pregnancy test

A blood test is performed 14 days after egg collection to confirm pregnancy.

What affects IVF success rates?

IVF success rates depend on several factors, with age being the most important.

Younger women generally have higher success rates, while success decreases with age. IVF success can also vary between clinics based on:

  1. Experience of specialists
  2. Laboratory quality
  3. Individualised care

It is also important to know that more than one IVF cycle may be required to achieve pregnancy.
 

Why choosing the right fertility clinic matters

IVF success is not only about the procedure itself. It is also about:

  1. The team guiding you
  2. The quality of care you receive
  3. The expertise behind every decision

Choosing a clinic with strong experience, advanced facilities and personalised support can significantly influence both outcomes and your overall experience.
