IVF Process Step by Step: Timeline, Injections and What to Expect

Medically reviewed by Dr. Manjushree Boob — MD, DNB, FICMCH, FICOG, Infertility & IVF Consultant, Shubham Hi-Tech Hospital and Test Tube Baby Centre, Amravati.

When a couple sits down in my clinic after being told they need IVF, the first question is rarely about success rates. It is usually much simpler: "Doctor, what actually happens? How many injections? How long will all this take?" The word IVF sounds enormous and mysterious, and that mystery is half of what makes it frightening. So let me take you through a full cycle the way I explain it across my desk — one step at a time, in order, with no jargon left unexplained.

A single IVF cycle, from the first injection to the pregnancy test, usually takes about two to three weeks of active treatment, sitting inside one menstrual cycle. Here is what each stage looks like.

Step 1: Preparation and Baseline Tests

Before any injection, we build a plan around your body. That means a few blood tests, a check of your AMH (a marker of ovarian reserve), a baseline ultrasound to count the resting follicles, and a semen analysis for your partner. This is also when we sit and talk — about your history, previous treatments, and any worry keeping you awake. Nothing about IVF is one-size-fits-all, and this groundwork is what lets me tailor your medicine doses rather than guess.

Step 2: Ovarian Stimulation (The Injection Phase)

This is the part everyone dreads and, honestly, the part most patients are relieved by once they start. Normally your ovaries release a single egg each month. In IVF, we use hormone injections for roughly nine to twelve days to encourage several follicles to grow together, so we have more than one egg to work with.

"Doctor, will I have to inject myself every day? I'm terrified of needles."

I hear this weekly, and I understand it completely. The injections are given with very fine, short needles into the fatty tissue of the lower tummy — not the deep, painful kind you imagine. Most women learn to do them at home within a day, and many tell me afterward that the fear was far worse than the reality. During this phase you come in every few days for a quick ultrasound and blood test so I can watch the follicles grow and adjust the dose. Think of it as careful gardening, not a fixed recipe.

Step 3: The Trigger Injection

When the follicles reach the right size, we give one final "trigger" injection at a precise time — often late at night. This matures the eggs and sets the clock. Egg retrieval then happens almost exactly 34 to 36 hours later, so the timing genuinely matters down to the hour. If I ask you to inject at 10 p.m. sharp, that is why.

Step 4: Egg Retrieval

This is a small procedure, done under short anaesthesia, and it takes only about fifteen to twenty minutes. Using ultrasound guidance, the fluid from each follicle is gently collected and the eggs are found in the laboratory. You are not aware of anything during it, and you rest for a couple of hours afterward. Most women go home the same day and feel a little bloated or crampy — similar to period discomfort — for a day or so.

Step 5: Fertilisation in the Laboratory

On the same day, the eggs meet the sperm. In conventional IVF, they are placed together and fertilisation happens naturally in the dish. In ICSI, a single healthy sperm is injected directly into each mature egg — we choose this route mainly when there is a sperm-quality concern. The next morning, the embryologist checks how many eggs have fertilised.

"If we get ten eggs, does that mean ten babies-in-waiting?"

No — and this is one of the most important things to understand, because it saves a lot of heartache. There is a natural drop-off at every step. Not every egg is mature, not every mature egg fertilises, and not every fertilised egg grows into a strong embryo. Getting several eggs but a smaller number of good embryos is completely normal, not a failure. It is exactly why we aim for more than one egg in the first place.

Step 6: Embryo Culture

The fertilised eggs are grown in a specialised incubator for three to five days. By day five, the strongest ones reach the "blastocyst" stage. Our embryologist watches them closely and grades them, so that when it is time to transfer, we choose the healthiest embryo with the best chance of implanting.

Step 7: Embryo Transfer

The transfer itself surprises people with how gentle it is. A thin, soft catheter carries the chosen embryo through the cervix into the uterus — no anaesthesia, no cutting, and it feels much like a routine internal examination. It takes a few minutes, you rest briefly, and then you go home. Any good-quality spare embryos can be frozen for a future attempt, which spares you the whole injection phase next time.

Step 8: The Two-Week Wait and the Pregnancy Test

Then comes the hardest part emotionally — the wait. For about two weeks you continue supportive hormone medicines, usually progesterone, to help the lining stay receptive. At the end of it, a simple blood test (beta hCG) tells us whether the embryo has implanted. I always ask my patients to avoid home urine kits during this window, as they can mislead and cause needless tears.

What to Expect at Your First Appointment

If you are only at the thinking stage, your first visit is nothing to fear. Bring any previous reports and your partner. We will talk through your history, do a scan and a few tests, and I will explain your particular options in plain words. You will leave with a clear picture and a written plan — not a rushed decision.
