How IVF works, step by step

Step 1: The first visit and planning

IVF usually starts with a consultation at a fertility clinic. You and the doctor review your goals, health history, past pregnancies if any, and any fertility testing you already have. The clinic may explain IVF, IUI, egg freezing, or other options depending on your situation.

Many people also do baseline testing before treatment starts. This can include bloodwork, ultrasound, and semen testing. The exact tests and timing vary by clinic and by person, so your own doctor is the right person to explain what applies to you.

If you are still deciding whether IVF makes sense for you, it may help to compare treatments and read more about understanding success rates. CoralConceive is a free matching service, not a clinic or medical provider, so we can help you explore options and connect with clinics near you, but not diagnose or treat.

• Consultation and review of goals
• Baseline testing may be recommended
• Your timeline depends on your cycle and clinic process

Step 2: Ovarian stimulation and monitoring

In a typical IVF cycle, the ovaries are stimulated with fertility medications for about 8 to 14 days so that more than one egg can mature. During this time, the clinic usually schedules several monitoring visits with blood tests and ultrasounds to check how the follicles are growing.

The goal is to time the next step carefully. Too early or too late can affect how many eggs are ready. Your doctor may adjust medication doses during monitoring, which is one reason IVF can feel intense and time-sensitive.

This phase can be physically and emotionally tiring. Some people feel bloated, sore, or stressed by the frequent appointments. If you want a fuller overview of timing, see how long IVF takes.

Step 3: The trigger shot and egg retrieval

When the follicles look ready, the clinic tells you when to take a final medication often called a trigger shot. This helps prepare the eggs for retrieval. Timing matters a lot here, and clinics usually give very specific instructions.

Egg retrieval is a short procedure done at the clinic or surgery center, usually with sedation. A doctor uses ultrasound guidance to collect eggs from the ovaries. Most people go home the same day, but recovery needs vary.

Not every follicle contains a mature egg, and not every egg collected will be usable. That can be disappointing if you were expecting the numbers to match exactly. This is a normal part of IVF, and your own doctor can explain what the results mean for you.

Step 4: Fertilization and embryo growth

After retrieval, the eggs are combined with sperm in the lab. In some cases, one sperm is injected directly into an egg, which is called ICSI. Whether standard fertilization or ICSI is used depends on the clinical situation and lab plan. You can read a simple explanation here: what is ICSI.

Over the next several days, the lab watches to see which eggs fertilize and which embryos keep developing. Some embryos stop growing, and that is common. The number of eggs retrieved is usually higher than the number of embryos available later.

Some cycles also include embryo testing or freezing all embryos for transfer later. Others may move toward a fresh transfer. Protocols differ, so this is something to review with a licensed fertility doctor at your clinic.

Step 5: Embryo transfer and the waiting period

If there is an embryo transfer, the clinic places an embryo into the uterus using a thin catheter. This is usually quicker and less invasive than retrieval. In some cycles, transfer happens a few days after retrieval. In others, embryos are frozen first and transfer happens in a later cycle.

After transfer, there is usually a waiting period before the pregnancy blood test. This part can be emotionally hard because you may have very little to do except follow clinic instructions and wait.

Success rates vary widely by age, diagnosis, egg and sperm factors, embryo development, and the clinic's lab and protocols. IVF can help many people, but it does not guarantee pregnancy or a baby in one cycle or at all. If you are comparing clinics, get matched or read answers to common questions about cost, timing, and referrals.

Step 6: Pregnancy test, next steps, and cost reality

About 9 to 14 days after transfer, the clinic usually does a blood test to check for pregnancy. If the test is positive, the clinic may repeat bloodwork and schedule early follow-up. If it is negative, the doctor may review what happened in the cycle and discuss possible next steps.

Sometimes IVF works in one cycle, and sometimes it takes more than one. Some people also learn that a different plan makes more sense after the first cycle. This uncertainty is one reason it helps to ask early about timelines, total expected costs, and what is included.

Typical IVF costs in the US can be high, and the total may change if medications, genetic testing, embryo freezing, storage, or multiple cycles are involved. General ranges are discussed in how much does IVF cost, but only a clinic can give you a real estimate for your care.
