IVF Process Timeline: Step-by-Step Guide from Start to Transfer

Complete IVF timeline from initial consultation to embryo transfer. Understand each phase, medications, and what to expect at every stage.

Understanding the IVF timeline helps you prepare mentally, physically, and logistically for treatment. From initial consultation to embryo transfer, a typical IVF cycle takes about 6-8 weeks. Here's what to expect at every stage.

Pre-Cycle Preparation (1-3 months before)

Before your IVF cycle begins, you'll complete:

  • Initial consultation: Review history, discuss protocol options
  • Diagnostic testing: Blood work (AMH, FSH, infectious disease), semen analysis, HSG or saline sonogram
  • Trial transfer: Practice transfer to measure uterine cavity
  • Consent and financial planning: Sign forms, arrange payment
  • Lifestyle optimization: Start prenatal vitamins, quit smoking, limit alcohol

Birth Control Priming (2-4 weeks)

Many protocols start with birth control pills to:

  • Synchronize follicle development
  • Allow scheduling flexibility
  • Suppress ovarian cysts
  • Prevent premature ovulation

Not all protocols use birth control. Some start directly with stimulation, especially for poor responders or natural cycle IVF.

Ovarian Stimulation (10-14 days)

The active treatment phase involves daily hormone injections:

  • Days 1-4: Begin FSH/LH injections (Gonal-F, Follistim, Menopur)
  • Days 5-7: First monitoring appointment (blood + ultrasound)
  • Days 8-10: Add GnRH antagonist (Cetrotide, Ganirelix) to prevent premature ovulation
  • Days 10-12: Final monitoring; dose adjustments as needed
  • Trigger day: HCG or Lupron trigger when follicles are mature (typically 18-22mm)

Egg Retrieval (Day 0)

36 hours after trigger injection:

  • Procedure takes 15-30 minutes under light sedation
  • Eggs retrieved via ultrasound-guided needle aspiration
  • You'll rest for 1-2 hours before going home
  • Plan to take the day off; mild cramping is normal
  • Partner provides sperm sample same day (or frozen sperm is thawed)

Fertilization and Embryo Development (Days 1-6)

In the laboratory:

  • Day 0: Eggs assessed for maturity; sperm prepared
  • Day 1: Fertilization check (normal is 70-80% with ICSI)
  • Day 3: Embryos at 6-8 cell stage
  • Day 5-6: Blastocyst stage; best embryos selected for transfer or biopsy
  • PGT-A (if doing): Cells biopsied Day 5-6; results in 1-2 weeks

This waiting period is emotionally intense. Your clinic will update you, typically on day 1, 3, and 5/6. Prepare for some embryo attrition—not all fertilized eggs become blastocysts.

Embryo Transfer (Day 5-6 or FET)

Transfer is a simple procedure:

  • Fresh transfer: Day 5-6 after retrieval
  • Frozen transfer (FET): Typically next cycle or later
  • Procedure takes 10-15 minutes, no sedation needed
  • Full bladder required for ultrasound guidance
  • Embryo placed in uterus via thin catheter
  • Rest briefly, then resume normal activities

Two-Week Wait (14 days post-transfer)

The hardest part of IVF for many people:

  • Continue progesterone support as prescribed
  • Beta HCG blood test typically 9-14 days after transfer
  • Avoid home pregnancy tests before scheduled beta
  • Normal activities are fine; bed rest is not required
  • If positive, continue medications and schedule follow-up betas and ultrasound

Key takeaways

  • A complete IVF cycle takes 6-8 weeks from start to pregnancy test
  • Stimulation phase requires 5-7 monitoring appointments
  • Egg retrieval is a minor procedure with quick recovery
  • Not all eggs become embryos—attrition is normal
  • The two-week wait is emotionally challenging; build in support

Frequently asked questions

How much time off work do I need?

Plan for retrieval day plus 1 day recovery. Transfer day is easier. Monitoring appointments (5-7 during stim) take 1-2 hours each, often early morning. Many people work through IVF with minimal time off.

Can I exercise during IVF?

Light exercise is fine early in stimulation. As ovaries enlarge, avoid high-impact activities, twisting, and heavy lifting to prevent ovarian torsion. Walking and gentle yoga are typically safe throughout.
