IVF Process Step by Step: Complete Guide from Consultation to Pregnancy

Step 1: Initial Consultation and Diagnostic Testing

Every IVF journey begins with understanding where you currently stand.

At your first consultation, your IVF specialist will take a detailed medical history and order a set of diagnostic tests. These typically include:

Blood tests to check hormone levels, including FSH, LH, oestradiol, and AMH (which indicates ovarian reserve)
An antral follicle count via ultrasound to assess how many eggs your ovaries are likely to produce
Semen analysis to evaluate sperm count, motility, and morphology
A uterine assessment, sometimes including a hysteroscopy if there's any concern about the uterine cavity

This stage is also your opportunity to ask every question on your mind. A good fertility specialist will take the time to explain your results clearly and outline what they mean for your treatment plan.

Step 2: Ovarian Stimulation

In a natural cycle, one egg matures and is released each month.

The goal of ovarian stimulation is to encourage the ovaries to produce several eggs in a single cycle, which gives the lab more options to work with and improves the chances of creating a successful embryo.

You'll be given hormone injections (gonadotrophins) over a period of 10 to 14 days.

During this time, you'll come in for regular monitoring scans and blood tests so your doctor can track how your follicles are responding and adjust the medication dose if needed.

This monitoring phase is one reason why being close to your IVF clinic matters practically.

What to Expect During Stimulation

Self-administered hormone injections at home
Regular ultrasound monitoring
Blood tests to assess hormone response
Medication adjustments when necessary

Common Side Effects

Bloating
Mild abdominal discomfort
Mood changes

Most patients find the injections become routine within a few days. Your fertility team will explain what to watch for and when to contact them.

Step 3: Egg Retrieval (OPU)

Once your follicles have reached the right size, you'll be given a trigger injection to mature the eggs.

Egg retrieval is scheduled approximately 36 hours later.

The procedure is carried out under light sedation, so you won't be awake for it.

Using an ultrasound-guided needle, the doctor retrieves fluid from each follicle. The procedure generally takes 20–30 minutes.

Recovery After Egg Retrieval

Most patients:

Return home the same day
Rest for one or two days
Experience mild cramping or spotting

Both are considered normal.

Important to Remember

Not every follicle contains a mature egg
Not every egg retrieved will fertilise successfully
Egg numbers vary significantly from patient to patient

Your doctor will provide realistic expectations based on your response to stimulation.

Step 4: Fertilisation in the Lab

On the same day as egg retrieval, a semen sample is collected and prepared.

The eggs and sperm are then brought together in the embryology laboratory.

Conventional IVF

In conventional IVF, eggs and sperm are placed together and fertilisation occurs naturally.

ICSI (Intracytoplasmic Sperm Injection)

For couples with male-factor infertility or previous fertilisation difficulties, ICSI may be recommended.

During ICSI:

A single healthy sperm is selected
The sperm is injected directly into a mature egg
Fertilisation is more controlled

This technique often improves fertilisation outcomes in appropriate cases.

Embryo Formation

Within approximately 24 hours, you'll receive an update on how many eggs fertilised successfully.

These fertilised eggs are now called embryos.

Step 5: Embryo Culture and Development

Fertilised embryos are cultured in the laboratory for three to five days.

Many fertility clinics prefer growing embryos to the blastocyst stage (Day 5) because blastocysts are:

More developed
Easier to assess for quality
More likely to implant successfully

Not all embryos will reach this stage, and that's completely expected.

Additional Procedures That May Be Recommended

Blastocyst Culture

Allows embryos to develop to Day 5 before transfer.

Laser-Assisted Hatching

A small opening is created in the embryo's outer shell to help implantation.

Genetic Testing

May be recommended for:

Recurrent implantation failure
Recurrent pregnancy loss
Genetic disease screening

Your fertility specialist will explain whether these options are relevant to your specific case.

Step 6: Embryo Transfer

Embryo transfer is one of the simplest parts of IVF treatment.

For most patients, it's painless and requires no anaesthesia.

A thin catheter is passed through the cervix, and the embryo is gently placed into the uterus.

What to Expect

Procedure time: approximately 10–15 minutes
No hospital stay required
Resume normal activities shortly afterwards

Endometrial Receptivity Analysis (ERA)

Some patients may benefit from ERA testing, which helps determine the precise timing when the uterine lining is most receptive to implantation.

This can be particularly useful for patients who have experienced failed transfers despite having good-quality embryos.

Embryo Freezing

If additional good-quality embryos are available:

They can be frozen for future use
Frozen embryo transfers offer success rates comparable to fresh transfers
Future cycles may be simpler and less expensive

Step 7: The Two-Week Wait

The period between embryo transfer and pregnancy testing is often emotionally challenging.

There are usually no major medical procedures during this time, leaving room for hope, anxiety, and anticipation.

During This Phase

You may be prescribed progesterone support, which may be given as:

Vaginal pessaries
Injections
Oral medication (in some cases)

Possible Symptoms

Some patients experience:

Mild cramping
Light spotting
Breast tenderness
Fatigue

These symptoms do not reliably indicate either success or failure.

Helpful Strategies

Stay active with gentle movement
Maintain a healthy diet
Follow medication instructions carefully
Lean on your support system

The goal is to continue normal life as much as possible while taking care of yourself.

Step 8: The Pregnancy Test

Approximately 14 days after embryo transfer, you'll undergo a blood test known as Beta hCG.

This test:

Detects pregnancy earlier than most home tests
Provides a quantitative hormone level
Offers greater accuracy

If the Result Is Positive

Your clinic will:

Confirm hormone progression
Schedule an early ultrasound
Check for fetal heartbeat development

If the Result Is Negative

Your fertility specialist will arrange a review consultation to:

Analyse the cycle
Identify potential improvements
Discuss next steps

It's important to remember that many successful pregnancies occur after more than one IVF cycle.

Each cycle provides valuable information that helps refine future treatment plans.

Starting Your IVF Journey With the Right Team

Understanding the IVF procedure is the first step.

The second is finding a fertility clinic and specialist you genuinely trust.

Yellow IVF combines experienced fertility specialists with advanced embryology laboratories across:

Gurgaon
South Delhi
Kolkata
Bhubaneswar
Rohtak
Kashmir

If you're considering IVF or simply want to understand your fertility treatment options, scheduling a consultation can provide clarity and personalised guidance before making any decisions.
