Understanding IVF Protocols

Antagonist (Short) Protocol

Most common protocol, typically 10-12 days of stimulation. GnRH antagonist prevents premature ovulation. Lower risk of OHSS, fewer injections than long protocol.

Best for: Normal responders, first IVF cycles, PCOS patients

Long Lupron Protocol

Starts with 2-3 weeks of down-regulation before stimulation. More control over cycle timing. May produce more eggs but higher OHSS risk.

Best for: Younger patients, those with regular cycles, endometriosis

Flare/Microdose Protocol

Uses small doses of Lupron to "flare" natural hormones. Designed for poor responders. Aims to maximize egg production with lower medication doses.

Best for: Poor responders, advanced maternal age, low AMH

Note: This timeline calculator provides estimates based on typical IVF protocols. Individual experiences vary significantly. Factors such as age, diagnosis, ovarian reserve, and clinic protocols will affect your actual timeline.

Understanding IVF Treatment Timelines

In vitro fertilization (IVF) involves a carefully orchestrated series of medical procedures that typically span 4-6 weeks. Understanding the timeline helps patients prepare mentally, physically, and logistically for their treatment cycle. Each protocol is designed to optimize egg production while maintaining precise control over ovulation timing to maximize success rates.

IVF protocols vary based on individual patient factors including age, ovarian reserve, previous response to medications, and specific fertility diagnoses. The three main protocols—long agonist, short agonist, and antagonist—each have distinct advantages and are selected based on your reproductive endocrinologist's assessment of your unique situation.

Modern IVF treatment achieves success rates of 30-50% per cycle depending on age and other factors, with many patients requiring multiple cycles. Understanding the process timeline helps set realistic expectations and enables better treatment planning with your medical team.

  • Stimulation: 10-14 days
  • Best for: Young patients, high ovarian reserve
Advantages: Excellent cycle control, prevents premature LH surge, good for freeze-all cycles

Short Agonist Protocol

  • Duration: 4-5 weeks total
  • Suppression: Minimal
  • Stimulation: 10-12 days
  • Best for: Poor responders, older patients
Advantages: Shorter treatment time, may improve response in poor responders

Antagonist Protocol

  • Duration: 3-4 weeks total
  • Suppression: None initially
  • Stimulation: 8-12 days
  • Best for: Most patients, PCOS, convenience
Advantages: Shorter cycles, lower OHSS risk, more patient-friendly

IVF Medication Guide

Ovarian Stimulation Medications

FSH Medications

  • Gonal-F (follitropin alfa): Recombinant FSH
  • Follistim (follitropin beta): Recombinant FSH
  • Bravelle (urofollitropin): Purified FSH
  • Typical dose: 150-450 IU daily

Combination Medications

  • Menopur (menotropins): FSH + LH activity
  • Repronex (menotropins): FSH + LH activity
  • Use: Often combined with FSH-only meds
  • Typical dose: 75-150 IU daily

Ovulation Prevention

GnRH Agonists

  • Lupron (leuprolide): Most common
  • Timing: Started 1-3 weeks before stims
  • Effect: Complete pituitary suppression
  • Side effects: Hot flashes, mood changes

GnRH Antagonists

  • Cetrotide (cetrorelix): Daily injection
  • Ganirelix: Daily injection
  • Timing: Started mid-stimulation
  • Advantage: Fewer side effects

Trigger and Support Medications

Ovulation Triggers

  • hCG (Pregnyl, Novarel): Traditional trigger
  • Lupron: For high OHSS risk
  • Dual trigger: Both hCG and Lupron
  • Timing: 35-36 hours before retrieval

Luteal Phase Support

  • Progesterone: Vaginal suppositories/gel
  • Estrace (estradiol): Support lining
  • Duration: Until 10-12 weeks if pregnant
  • Monitoring: Regular blood levels

Monitoring Schedule and What to Expect

Baseline Monitoring (Day 1-3)

Ultrasound Assessment

  • • Antral follicle count (AFC)
  • • Check for ovarian cysts
  • • Measure endometrial thickness
  • • Assess ovarian size and position

Hormone Levels

  • • FSH (should be <10-12 IU/L)
  • • LH (baseline levels)
  • • Estradiol (<50 pg/mL if suppressed)
  • • Progesterone (<1.5 ng/mL)

Stimulation Monitoring (Days 5-11)

Day 5-6 Check

  • • Retrieval scheduling

Optimal Trigger Criteria

  • Lead follicles: 2-3 follicles ≥18mm diameter

Frequently Asked Questions

How long does an IVF cycle take from start to finish?

A complete IVF cycle typically takes 4-8 weeks depending on the protocol used. Antagonist protocols are shortest at 3-4 weeks, while long agonist protocols can take 6-8 weeks including the suppression phase. Fresh transfers occur 3-5 days after egg retrieval, while frozen transfers may be scheduled weeks or months later.

What if my cycle gets cancelled?

Cycle cancellation occurs in 5-20% of IVF cycles due to poor response, over-response, or other medical factors. Cancellation before egg retrieval allows medication adjustments for future cycles. While disappointing, cancelled cycles provide valuable information for optimizing future treatment protocols.

How painful are the injections?

Most IVF injections use very thin needles similar to insulin injections. Subcutaneous injections (like Gonal-F, Follistim) cause minimal discomfort. Intramuscular progesterone injections are more uncomfortable but manageable. Your clinic will provide training and tips to minimize discomfort.

Can I work during IVF treatment?

Most patients can work normally during IVF with some schedule flexibility for monitoring appointments. You may need time off for egg retrieval (1-2 days) and transfer day. Some prefer lighter schedules during stimulation due to fatigue, bloating, or emotional stress.

What are the success rates for different age groups?

Success rates vary significantly by age: under 35 (40-50% per cycle), 35-37 (35-40%), 38-40 (25-35%), 41-42 (15-25%), over 42 (5-15%). These rates include fresh and frozen embryo transfers. Individual factors like ovarian reserve, diagnosis, and clinic expertise also impact success rates.

Should I do genetic testing on embryos?

Preimplantation genetic testing (PGT) can identify chromosomally normal embryos, potentially improving success rates and reducing miscarriage risk. It's often recommended for patients over 35, those with recurrent pregnancy loss, or known genetic conditions. However, it adds time and cost to treatment.
