What Are the 5 Stages of IVF?

IVF has 5 stages:- ovarian stimulation (10–14 days), egg retrieval (1 day), fertilisation and embryo culture (3–5 days), embryo transfer (1 day), and the two-week wait before the pregnancy test. A complete IVF cycle from start to result takes approximately 4–6 weeks.

Starting IVF can feel overwhelming especially when you are trying to understand what is going to happen to your body, when, and why.

This guide walks you through every stage of the IVF process in plain language: what happens, how long it takes, what you will feel physically and emotionally, and what your medical team is looking for at each step.

If you are considering IVF at Mamata Fertility Hospital, Hyderabad or any fertility centre this is the foundation you need before your first consultation.

IVF at a Glance: The 5 Stages and Timeline

Before Stage 1 begins: Most IVF protocols include a preparatory phase  blood tests, baseline scan, medication instruction session, and sometimes a 2–4 week course of oral contraceptive pills or a short GnRH agonist course to synchronise your cycle. Add 2–4 weeks to the above for a full picture.

Stage 1 — Ovarian Stimulation (Days 1–12)

What Is the Goal?

In a natural cycle, your body selects one dominant egg. IVF needs more. Ovarian stimulation uses daily hormonal injections to encourage your ovaries to grow multiple follicles  each one containing a potential egg. More eggs retrieved = more embryos created = more chances of a successful transfer.

What Medications Are Used?

Your fertility specialist prescribes a personalised stimulation protocol based on your AMH level, antral follicle count (AFC), age, and body weight. Common medications include:

• FSH injections (Follicle Stimulating Hormone) Gonal-F, Fostimon, Folisurge — the main stimulation medication
• LH injections (Luteinising Hormone)  Menopur — often combined with FSH
• GnRH antagonist (Cetrotide, Ganirelix)  started mid-stimulation to prevent premature ovulation
• GnRH agonist (Lupride) used in “long protocol” or as the trigger in high-risk patients

Injections are typically self-administered subcutaneously (under the skin of the lower abdomen) once daily. Our nursing team at Mamata demonstrates the technique and is available to answer questions throughout your cycle.

Monitoring During Stimulation

Every 2–3 days, you will attend the clinic for:

• Ultrasound scan — to count follicles and measure their size (target: 18–20mm before triggering)
• Blood tests — oestradiol levels to confirm follicles are maturing

Dose adjustments are made based on your response. This is why monitoring matters: stimulating too aggressively can lead to OHSS (ovarian hyperstimulation syndrome), while under-stimulation produces too few eggs. The sweet spot is different for every patient.

The Trigger Injection

When follicles reach the right size (typically 18–20mm), you receive a single trigger injection — usually hCG (Pregnyl, Ovidrel) or Lupride, which causes the final maturation of the eggs. Egg retrieval is scheduled exactly 36 hours later. This timing is critical  do not take the trigger injection at the wrong time.

What You Might Feel?

• Bloating and abdominal heaviness as follicles grow
• Mood fluctuations from hormonal changes
• Mild breast tenderness
• Fatigue

These are expected responses, not warning signs. If you experience severe pain, rapid weight gain, or reduced urination, contact your clinic immediately these can signal OHSS.

Stage 2 — Egg Retrieval (Day 12–14)

What Happens During the Procedure?

Egg retrieval (also called follicle aspiration or ovum pick-up / OPU) is performed under IV sedation so you are comfortable and unaware during the procedure. It takes 20–30 minutes.

Using transvaginal ultrasound guidance, your doctor inserts a fine needle through the vaginal wall into each follicle and gently aspirates the fluid containing the egg. The embryologist in the adjacent lab examines each sample immediately and identifies the eggs under a microscope.

How Many Eggs Should You Expect?

The number retrieved depends on your ovarian reserve and stimulation response. A typical cycle retrieves 8–15 eggs, though this varies widely. Not all retrieved eggs will be mature, and not all mature eggs will fertilise which is why retrieving more eggs gives a better chance overall.

These are averages. Individual results vary significantly.

What You Might Feel

• Drowsiness from sedation you will need someone to drive you home
• Mild cramping and pelvic discomfort for 1–2 days
• Light spotting
• Bloating (especially if many follicles were stimulated)

Rest at home for the remainder of the day. Most patients return to normal activity the next day.

Stage 3 — Fertilisation and Embryo Culture (Days 1–5 After Retrieval)

Fertilisation: IVF or ICSI?

In the embryology lab, your eggs and partner’s (or donor) sperm are fertilised using one of two methods:

Conventional IVF: Eggs and sperm are placed together in a dish and sperm fertilise the eggs naturally. Used when sperm count and motility are normal.

ICSI (Intracytoplasmic Sperm Injection): A single sperm is injected directly into each mature egg using a microscopic needle. Used in cases of low sperm count, poor motility, high DNA fragmentation, or previous failed fertilisation.

Your embryologist selects the method best suited to your specific case. At Mamata Fertility Hospital, Hyderabad, ICSI is performed using advanced micromanipulation equipment, maximising fertilisation rates even in challenging male factor cases.

What Happens Over Days 1–5?

Day 3 vs Blastocyst Transfer — What Is the Difference?

Day 3 transfer: Embryo is transferred earlier, when it has 6–8 cells. Suitable when fewer embryos are available.

Blastocyst transfer (Day 5): The embryo is cultured for 2 more days. Only the strongest embryos survive to blastocyst so those that do have a significantly higher implantation rate. If you have multiple good-quality embryos, your doctor will usually recommend culturing to blastocyst for the best single embryo selection.

Embryo Grading

Embryologists grade embryos on cell number, symmetry, and fragmentation (Day 3) or expansion and inner cell mass quality (blastocyst). The best-graded embryo is selected for transfer. Remaining viable embryos are vitrified (flash-frozen) for future use in FET (Frozen Embryo Transfer) cycles.

What You Are Doing During This Time

You are at home, resting. Your clinic will call you on Day 1 (fertilisation report) and again before transfer to confirm the embryo’s progress. This waiting phase is its own emotional challenge not knowing what is happening in the lab is hard. A call from your embryology team each day helps.

The quality of your embryology lab directly affects your IVF outcome.
Mamata’s embryology team uses time-lapse monitoring and advanced vitrification to maximise embryo development and freeze quality.

Stage 4 — Embryo Transfer (Day 3 or Day 5 After Retrieval)

What Happens?

Embryo transfer is the simplest procedure in the IVF cycle. No sedation is required most patients say it feels similar to a cervical smear test.

You lie on the procedure table with a full bladder (this helps visualise the uterus on ultrasound). Your doctor passes a thin, flexible catheter through the cervix into the uterus. The embryologist loads the selected embryo(s) into the catheter tip, and the doctor gently deposits them at the optimal position in the uterine cavity, guided by ultrasound.

The procedure takes 5–10 minutes. You can watch the transfer on the ultrasound monitor if you wish.

How Many Embryos Are Transferred?

In most cases, a single embryo is transferred (Single Embryo Transfer / SET). This is the international best-practice standard:

• Twin pregnancies carry significantly higher risk for mother and babies
• Blastocyst SET success rates now rival double embryo transfer in suitable patients
• Remaining embryos can be frozen and used in future FET cycles

Multiple embryo transfer may be considered in older patients or when embryo quality is limited  discussed with your doctor case by case.

Immediately After Transfer

• You can go home within 30–60 minutes
• Light activity is fine — full bed rest is NOT required or recommended
• Avoid strenuous exercise, hot baths, and sexual intercourse until after the pregnancy test
• Continue all prescribed medications (progesterone and oestrogen supplementation)
• Do not take an over-the-counter pregnancy test before Day 14 — hCG from the trigger injection can cause false positives

Stage 5 — The Two-Week Wait (Days 1–14 After Transfer)

Why Is It Called the Two-Week Wait?

After the embryo is transferred, it takes approximately 6–10 days for the embryo to implant into the uterine lining and for hCG (pregnancy hormone) to build to levels detectable by a blood test. You cannot accurately test any earlier. This 14-day period  often called the “2WW”  is universally described as the hardest part of IVF.

What Is Happening Inside Your Body?

What You Might Feel (and What It Means)

This is important: symptoms — or lack of them — are not reliable indicators of success. Many patients have no symptoms and get a positive result. Some have every symptom and get a negative. The progesterone medication you are taking causes many “pregnancy-like” symptoms regardless of outcome.

Common feelings during the 2WW:

• Cramping (from implantation or progesterone)
• Breast tenderness (from progesterone)
• Bloating
• Fatigue
• Spotting (can be implantation bleeding — not a sign of failure)
• Anxiety, mood swings, difficulty sleeping

How to Get Through the Two-Week Wait?

• Continue medications exactly as prescribed — do not stop progesterone early
• Stay gently active — short walks are fine and good for mental health
• Avoid symptom-Googling — it will not help and almost always increases anxiety
• Lean on your support system — partner, close friend, or a fertility support group
• At Mamata, our counsellors are available during this period — ask your coordinator for support contact details

The Pregnancy Blood Test (Beta hCG)

On Day 14 post-transfer, you have a blood test at the clinic measuring your beta-hCG level. A positive result (hCG above threshold) means the embryo has implanted. A second test is done 48 hours later to confirm the level is rising appropriately.

If the result is positive: Your care transitions to early pregnancy monitoring — scans at 6 and 8 weeks to confirm fetal heartbeat.

If the result is negative: Your IVF Specialist will schedule a follow-up consultation to review your cycle, discuss what may have affected the outcome, and plan next steps — whether that is a FET cycle (using your frozen embryos), a modified protocol, or a break before the next cycle.

A negative result is not the end. Most patients at Mamata who achieve pregnancy do so within 2–3 cycles. Your embryology and clinical team will use the information from each cycle to improve the next.

IVF vs IUI — Which Is Right for You?

IVF is not the first step for every couple. IUI (Intrauterine Insemination) is a simpler, less invasive, and less expensive procedure that may be recommended first when:

• Sperm count and Sperm motility are near-normal
• Fallopian tubes are open
• No significant female fertility issue is present
• Infertility is unexplained (first-line treatment)

IUI involves placing prepared sperm directly into the uterus at the time of ovulation — no egg retrieval, no lab fertilisation.

Explore the difference between IVF and IUI

If IUI has been unsuccessful after 3–4 cycles, or if your diagnosis indicates IVF is more appropriate, your specialist will recommend moving to IVF.

Frequently Asked Questions About IVF Stages

How long does one IVF cycle take from start to pregnancy test?

– A complete IVF cycle from the first injection to the pregnancy blood test takes approximately 4–6 weeks. If you include the preparatory phase (baseline tests, contraceptive pill alignment), the total time is typically 6–8 weeks from your first appointment to results.

Is the IVF process painful?

– Most stages are not painful. Daily injections cause mild discomfort at the injection site. Egg retrieval is done under sedation you will not feel it. Embryo transfer requires no sedation and feels similar to a smear test. The main discomfort is bloating during stimulation and mild cramping after retrieval.

How many eggs does a typical IVF cycle produce?

– Most cycles retrieve 8–15 mature eggs, though this varies widely based on age and ovarian reserve. Women with lower AMH may retrieve fewer eggs; those with PCOS may produce more. Not all retrieved eggs will fertilise, and not all fertilised eggs will develop to blastocyst stage.

What is a blastocyst transfer, and is it better than a Day 3 transfer?

– A blastocyst is a Day 5 embryo that has developed to a more advanced stage. Blastocysts have higher implantation rates than Day 3 embryos, so transferring a blastocyst generally gives better success rates per transfer. Your doctor will recommend Day 5 culture if you have enough good-quality embryos to make it viable.

What happens to extra embryos after transfer?

– Surplus viable embryos are vitrified (flash-frozen) and stored. These can be used in future Frozen Embryo Transfer (FET) cycles — which are shorter, cheaper, and less physically demanding than a full stimulation cycle.

Pregnancy Testing and Next Steps

At the end of the two-week wait, a blood test is conducted to measure hormone levels and confirm pregnancy. A positive result marks the beginning of an exciting new chapter, while a negative result may lead to discussions with your gynecologist about next steps and potential future cycles.

Mamata Fertility offer continued support and guidance, regardless of the outcome. They work closely with patients to develop personalized plans tailored to individual circumstances and aspirations.
