IVF Process: A Complete Step-by-Step Guide
The IVF process is a series of carefully planned steps that help eggs and sperm meet in a laboratory and support the development of an embryo before it is transferred to the uterus. IVF, or in vitro fertilization, may be recommended for different causes of infertility, depending on the individual or couple’s fertility assessment.
At Flora Fertility Centre, our fertility specialists create a personalised treatment plan based on your medical history, test results, age, ovarian reserve, and other factors. While every IVF journey is different, understanding the IVF treatment process can help you know what to expect at each stage.
What Is the IVF Process?
The IVF process involves stimulating the ovaries to develop eggs, retrieving the eggs, fertilizing them with sperm in the laboratory, allowing embryos to develop, and transferring a suitable embryo into the uterus.
The main stages usually include:
- Initial consultation and fertility assessment
- Ovarian stimulation
- Monitoring and trigger injection
- Egg retrieval
- Sperm collection
- Fertilization
- Embryo development
- Embryo transfer
- Pregnancy testing
The exact medications, timing, and number of steps can vary from person to person.
IVF Process Step by Step
1. Initial Consultation and Fertility Assessment
The first step is to meet an IVF specialist. During your consultation, your doctor will review your medical history, previous fertility treatments, menstrual history, and any available test results.
You may have fertility tests such as blood tests, ultrasound scans, or an assessment of ovarian reserve. Depending on your circumstances, your partner may also undergo a semen analysis.
Based on these findings, your fertility specialist will explain whether IVF may be appropriate and develop a treatment plan suited to your needs.
2. Ovarian Stimulation
In a natural menstrual cycle, usually one egg reaches maturity. During IVF, fertility medicines are used to encourage the ovaries to develop multiple follicles so that several eggs may be available for retrieval.
Stimulation commonly lasts around 8–14 days, although the duration can vary.
During this stage, your doctor will monitor your response through ultrasound scans and, when needed, blood tests. The medication dose may be adjusted depending on how your ovaries respond.
3. Monitoring and the Trigger Injection
Regular monitoring helps your fertility team determine when the follicles are ready for egg retrieval.
When the follicles have developed appropriately, a trigger injection is given to help the eggs complete their final stage of maturation.
The timing of the trigger is important because egg retrieval is usually scheduled approximately 34–36 hours later, depending on your treatment plan.
4. Egg Retrieval
Egg retrieval, also called oocyte retrieval, is the procedure used to collect mature eggs from the ovaries.
It is generally performed under sedation or anesthesia. Using ultrasound guidance, the fertility specialist passes a thin needle through the vagina to reach the ovarian follicles and gently collects the fluid containing the eggs.
The procedure itself is usually completed within about 20–30 minutes, although the exact duration can vary.
The number of eggs retrieved differs from person to person. It depends on factors such as age, ovarian reserve, and response to stimulation, so there is no single number that is considered normal for everyone.
5. Sperm Collection
Sperm is generally collected around the time of egg retrieval when fresh sperm is being used.
The laboratory team assesses the semen sample and prepares suitable sperm for fertilization. If frozen or donor sperm is being used, it may already be prepared for use according to the treatment plan.
In some situations, specialized sperm-retrieval procedures may be recommended if sperm cannot be obtained through ejaculation.
6. Fertilization
Once the eggs and sperm are prepared, fertilization takes place in the laboratory.
There are different ways fertilization may be performed. In conventional IVF, prepared sperm is placed with the eggs in a laboratory dish. In some cases, intracytoplasmic sperm injection (ICSI) may be recommended, where a single sperm is injected directly into an egg.
Your fertility specialist will explain which approach is appropriate based on your individual circumstances.
7. Embryo Development
After fertilization, the laboratory team monitors the embryos as they develop.
A fertilized egg first develops into an early embryo and continues developing over the following days. Some embryos may reach the blastocyst stage around day 5 or 6.
Embryologists carefully monitor embryo development and assess the embryos according to established laboratory criteria. Not every fertilized egg will continue developing into a blastocyst, which is a normal part of the IVF process.
Depending on your treatment plan, embryo freezing or other laboratory procedures may also be considered.
8. Embryo Transfer
Embryo transfer is the stage where a selected embryo is placed into the uterus.
A thin, flexible catheter is gently passed through the cervix into the uterus. The embryo is then released into the uterine cavity.
Embryo transfer is usually a short procedure and generally does not require general anesthesia. Your doctor will guide you on what to expect before and after the procedure.
In some cases, embryos may be frozen and transferred in a later menstrual cycle rather than immediately after egg retrieval.
9. Pregnancy Test
After embryo transfer, you will need to wait before taking a pregnancy test.
Your fertility specialist will advise you when to have a blood pregnancy test, which measures human chorionic gonadotropin (hCG).
Testing too early can sometimes give an unclear or misleading result, so it is important to follow the timing recommended by your fertility team.
If the test is positive, your specialist will guide you through the next steps, which may include follow-up blood tests and an ultrasound scan to assess the pregnancy.
IVF Process Step-by-Step Timeline
The IVF process step-by-step timeline is not the same for every patient. A typical cycle may look like this:
| IVF Stage | Approximate Timing |
|---|---|
| Initial consultation and testing | Before treatment begins |
| Ovarian stimulation | Around 8–14 days |
| Trigger injection | Around 34–36 hours before egg retrieval |
| Egg retrieval | One day |
| Fertilization | Same day as egg retrieval |
| Embryo development | Around 5–6 days |
| Embryo transfer | Fresh or in a later cycle, depending on the plan |
| Pregnancy test | As advised by your fertility specialist |
Your doctor may recommend a different schedule depending on your ovarian response, treatment protocol, and whether fresh or frozen embryo transfer is planned.
What Happens After Embryo Transfer?
After embryo transfer, most people can return to their normal routine unless their doctor advises otherwise.
You may experience mild cramping, bloating, or light spotting, but symptoms vary from person to person. These symptoms alone cannot confirm whether implantation or pregnancy has occurred.
Continue any prescribed medicines exactly as advised by our fertility specialist and attend your scheduled pregnancy test.
If you experience severe pain, heavy bleeding, breathing difficulty or other concerning symptoms, contact your fertility team promptly.
How Long Does the IVF Process Take?
The length of an IVF cycle varies depending on the treatment protocol and whether a fresh or frozen embryo transfer is planned.
The ovarian stimulation phase often takes around 8–14 days, followed by egg retrieval and embryo development. If a fresh transfer is suitable, embryo transfer may take place a few days after egg retrieval. If a frozen embryo transfer is planned, the transfer may happen during a later cycle.
Your fertility specialist can provide a more accurate timeline after reviewing your individual treatment plan.
What Can Affect IVF Treatment Outcomes?
IVF outcomes can vary significantly between individuals. Factors that may influence the chances of success include:
- Age
- Ovarian reserve
- Egg and embryo quality
- Sperm quality
- Underlying fertility conditions
- Uterine or reproductive health
- Previous fertility treatment history
- Embryo development
- Overall health and lifestyle
There is no single IVF success rate that applies to everyone. Your fertility specialist can explain your individual circumstances and expected outcomes after your assessment.
