How IVF Works Step by Step | Nahal Fertility Toronto

Wondering how IVF works step-by-step? Understanding the IVF process helps reduce stress and prepares you for what to expect along the way. At Nahal Fertility Clinic in Toronto, we walk every patient through a personalized IVF journey based on their specific fertility goals, age, and medical profile.

Whether you’re new to fertility treatment or transitioning from IUI, this guide outlines each phase of the IVF process, from consultation to embryo transfer and pregnancy testing.

What Is IVF?

In Vitro Fertilization (IVF) is an assisted reproductive technology (ART) used to help individuals and couples conceive. The process involves retrieving eggs, fertilizing them in a lab with sperm, and transferring a healthy embryo into the uterus.

IVF is often recommended for:

  • Patients with blocked or damaged fallopian tubes
  • Low ovarian reserve or age-related fertility decline
  • Unexplained infertility
  • Male-factor infertility
  • Couples or individuals using donor eggs, sperm, or embryos
  • Those requiring genetic testing to avoid passing on inherited conditions

Step 1: Initial Fertility Consultation

The first step in any IVF journey is a thorough fertility consultation. During this appointment, your doctor will:

  • Review your medical and reproductive history
  • Recommend fertility testing (bloodwork, ultrasounds, semen analysis)
  • Discuss treatment options and tailor your IVF plan

If IVF is the right path, we’ll build your protocol and timeline right away.

Step 2: Ovarian Stimulation

You’ll begin hormone injections to stimulate your ovaries to produce multiple eggs instead of just one. This phase typically lasts 8–12 days and includes:

  • Daily hormone injections at home
  • Monitoring via bloodwork and ultrasound
  • Adjustments to medication based on your response

The goal is to safely develop mature follicles that contain high-quality eggs.

Step 3: Trigger Shot and Egg Retrieval

Once your follicles reach ideal size, a final injection (trigger shot) is administered to mature the eggs for collection. Roughly 36 hours later, you’ll undergo:

  • A minor, outpatient egg retrieval procedure
  • Sedation for comfort
  • Recovery within a few hours

Our embryology team then fertilizes the retrieved eggs using standard IVF or ICSI (Intracytoplasmic Sperm Injection), depending on your case.

Step 4: Embryo Development and PGT Testing (Optional)

Fertilized embryos are monitored in our state-of-the-art lab for 5–7 days until they reach the blastocyst stage. At this point, you may choose to undergo Preimplantation Genetic Testing (PGT-A or PGT-M) to:

  • Screen for chromosomal abnormalities
  • Avoid passing on single-gene disorders
  • Select the healthiest embryo for transfer

Embryos can be transferred fresh or frozen depending on your plan and test results.

Step 5: Embryo Transfer

The embryo transfer is a quick and painless procedure where a selected embryo is placed into the uterus using ultrasound guidance.

  • No anesthesia required
  • Performed in our clinic
  • You may resume light activity after the procedure

Depending on your case, you may transfer one embryo or more (though single embryo transfer is often recommended to reduce risks).

Step 6: Two-Week Wait and Pregnancy Testing

After the transfer, you’ll enter the “two-week wait” before your pregnancy test. This can be the most emotionally challenging part of IVF, so we offer full support during this time.

  • Blood pregnancy test is done about 10–14 days after transfer
  • If positive, early pregnancy ultrasounds will follow
  • If negative, we’ll discuss next steps with care and sensitivity

Optional: Embryo Freezing and Future Transfers

Any additional healthy embryos can be frozen (cryopreserved) for future use. This offers:

  • The ability to try again without repeating stimulation
  • Family planning flexibility
  • Lower costs for subsequent transfers

Our fertility preservation program ensures your embryos are securely stored and monitored.
