Understanding the IVF Process: A Step-by-Step Guide

In vitro fertilisation (IVF) is a widely used fertility treatment that helps people achieve pregnancy when natural conception is challenging. Understanding the IVF process can help you feel more informed and empowered as you navigate your fertility journey. In this guide, we’ll break down each stage of IVF, explain what you can expect, and offer practical advice on preparing for each step.

What is IVF?

IVF, is a fertility treatment where an egg and sperm are combined outside the body in a laboratory setting. Once fertilisation occurs, the resulting embryo is transferred into the uterus, with the hope that it will implant and lead to a successful pregnancy.

Who is IVF for?

IVF can be an effective option for various individuals and couples, including those dealing with:

While IVF offers hope to many, it’s important to understand that success rates can vary based on factors like age and overall health.  

Step-by-Step Breakdown of the IVF Process

The IVF process involves several stages, each critical to the success of treatment. Here’s a breakdown of what happens during each phase:

1. Initial Consultation and Assessment

The first step in the IVF process is an initial consultation with a fertility specialist. During this appointment, your doctor will:

  • Review your medical history and any previous fertility treatments.
  • Order tests such as blood work and ultrasounds to assess your reproductive health.
  • Discuss your treatment options, timeline, and expected success rates based on your age and health.

2. Ovarian Stimulation

Once you decide to proceed with IVF, the next phase is ovarian stimulation. The goal here is to encourage your ovaries to produce multiple eggs, rather than the single egg that typically develops during a natural menstrual cycle.

  • Medications: You’ll take injectable hormone medications (usually over 10–14 days) to stimulate egg production. These include follicle-stimulating hormone (FSH) and luteinising hormone (LH).
  • Monitoring: Your progress will be monitored with blood tests and ultrasounds to track follicle growth (fluid-filled sacs containing the eggs).
  • Trigger Injection: Once the follicles have reached an optimal size, you’ll receive a “trigger” shot of human chorionic gonadotropin (hCG) to finalise egg maturation.

Tip: It’s important to follow your medication schedule closely during this phase to ensure your eggs are ready for retrieval.

3. Egg Retrieval

Approximately 36 hours after the trigger injection, your eggs will be collected in a minor surgical procedure known as egg retrieval.

  • Anaesthesia: You’ll be sedated during the procedure, which typically lasts 20–30 minutes.
  • Procedure: Using ultrasound guidance, a thin needle is inserted through the vaginal wall to retrieve the eggs from the follicles.
  • Post-Procedure: You may experience mild cramping or spotting afterward, but most people recover quickly.

The retrieved eggs are immediately taken to the lab for fertilisation.

4. Sperm Collection and Fertilisation

While the eggs are being retrieved, a sperm sample is also collected (or thawed if using donor or frozen sperm). The sperm is then processed and combined with the eggs to achieve fertilisation in one of two ways:

  • Conventional IVF: The eggs and sperm are placed together in a petri dish and left to fertilise naturally.
  • ICSI (Intracytoplasmic Sperm Injection): A single sperm is directly injected into each egg. This method is often used if sperm quality is a concern.

Once fertilisation occurs, the fertilised eggs (now embryos) are monitored for 3 to 5 days as they develop.

5. Embryo Transfer

After the embryos have developed for a few days, one (or in rare cases more) will be selected for transfer into the uterus. This may be a fresh embryo transfer or a frozen embryo transfer.

  • Procedure: The embryo transfer is a simple, painless procedure that doesn’t require anaesthesia. A thin catheter is used to place the embryo into the uterus.
  • Post-Transfer: After the transfer, you may be advised to rest briefly, though most people can resume normal activities shortly after.

The remaining viable embryos may be frozen for future use if desired.

6. The Two-Week Wait

After the embryo transfer, you’ll enter what’s known as the “two-week wait,” the period before you can take a pregnancy test to determine if the IVF process was successful.

  • Hormone Support: You may be prescribed progesterone to support the uterine lining and encourage implantation.
  • Emotional Support: This waiting period can be emotionally challenging for many people. It’s important to focus on self-care, maintain healthy habits, and seek support if needed.

Approximately 10–14 days after the embryo transfer, you’ll take a blood test to measure hCG levels (the pregnancy hormone) and confirm whether implantation has occurred.

7. Pregnancy Test and Next Steps

The blood test will reveal if the IVF process resulted in pregnancy. If the test is positive, your fertility clinic will schedule follow-up appointments to monitor the early stages of pregnancy. If the result is negative, your specialist will discuss your options for further cycles or alternative treatments.

IVF Success Rates: What You Should Know

IVF success rates vary depending on several factors, including:

According to recent data, the average IVF success rate is around 40% for women under 35, but this rate decreases as age increases. Your fertility specialist will provide you with personalised success rates based on your unique circumstances.
