In short: Most couples considering IVF ask the same question: how long does the whole process actually take, and what happens each week? This article walks through the timeline from your first appointment to the pregnancy test, day by day.

How long does IVF take overall?

Once your preparation tests are complete and there’s no additional obstacle, a single IVF cycle typically takes about 4 to 6 weeks from the start of your menstrual cycle to the pregnancy test. This doesn’t include the preparation phase — initial evaluation, hormone testing, and your partner’s semen analysis if needed — which can take anywhere from a few days to a few weeks depending on the patient. If a frozen embryo transfer (FET) is planned or genetic testing (PGT) results are pending, the total timeline can extend by a few more weeks.

Step-by-step timeline

• 1. Evaluation and preparation (variable, usually 1-3 weeks): First consultation, hormone tests, ultrasound assessment, and your partner’s semen analysis if needed.
• 2. Ovarian stimulation (10-14 days): Daily injections begin with your period; your ovaries are monitored regularly with ultrasound and blood tests.
• 3. Trigger shot and egg retrieval (about 36 hours later): Once the eggs reach the right size, a trigger shot matures them; the retrieval procedure (OPU) itself takes 15-20 minutes.
• 4. Fertilization check (18-20 hours later): The lab checks whether fertilization has occurred.
• 5. Embryo development and transfer day (2-5 days): Embryos are monitored, and the transfer day is chosen based on their development.
• 6. Two-week wait after transfer (12-14 days): Hormone support continues during this time, until it’s time for the blood pregnancy test (β-hCG).

For the clinical detail of exactly what happens at each stage, our IVF treatment in Istanbul page covers the full process; this article focuses specifically on how long each part takes and what to expect week by week.

What can make the process take longer?

• Genetic testing (PGT/NGS): Results can take anywhere from a few days to a few weeks, in which case a frozen embryo transfer (FET) is planned instead of a fresh one.
• Ovarian cysts or hormonal imbalance: These may need to be addressed before treatment can begin.
• A long stimulation protocol: This requires suppressing the ovaries first, which extends the medication period.
• A frozen transfer cycle: Preparing the uterine lining can take an additional 2-4 weeks. We compare the two approaches in our article on fresh vs. frozen embryo transfer.

What to expect along the way

During ovarian stimulation, daily injections and frequent ultrasound or blood monitoring are normal, and most patients can continue with work and daily life. Egg retrieval is done under brief anesthesia, and patients usually go home the same day. Embryo transfer is a short, painless procedure that takes only a few minutes. The 12-14 day wait after transfer is, for most patients, the emotionally hardest part of the process — testing early is not recommended, since it can give misleading results.

What can you do to improve your chances?

How you prepare matters just as much as how long the process takes. We cover what to focus on before starting treatment in our article on preparing for IVF and improving your chances. If you’re wondering how your age and ovarian reserve might affect your timeline, our article on IVF success rates by age may also help.
