If you've been trying to conceive and feel like the only options in front of you are "keep trying and hoping" or "go straight to IVF," we want you to know: there's a smarter step in between. One that's grounded in clinical science, led by one of the country's most respected fertility specialists, and designed to work with your body — not around it.
It's called the F.A.S.T. Method, and it's the foundation of Dr. Aimee Eyvazzadeh's fertility program, available exclusively through Proov.
What Is the F.A.S.T. Method?
The F.A.S.T. Method is a structured, four-step clinical protocol designed to optimize your fertility at home — before jumping to expensive, invasive interventions. Developed by Dr. Aimee Eyvazzadeh (affectionately known as "The Egg Whisperer"), a Reproductive Endocrinologist with credentials from UCLA, Harvard, and the University of Michigan, the F.A.S.T. Method brings the same targeted approach used inside fertility clinics directly to you.
Each letter represents a critical pillar of the conception process:
-
F — Follicle Development (supported by Metformin, when clinically indicated)
-
A — Assisted Ovulation (supported by Letrozole)
-
S — Support Implantation (supported by progesterone)
-
T — Time Intercourse Perfectly (guided by real-time hormone data in the Proov app)
This isn't guesswork. It's the kind of targeted, data-driven protocol that was previously only available inside a fertility clinic — now accessible from your own bathroom, with a real doctor reviewing your results.
Breaking Down Each Step of F.A.S.T.
F — Follicle Development
Before an egg can be released, it has to develop properly inside a follicle — and for some women, that process is quietly being disrupted by elevated insulin levels, metabolic imbalances, or PCOS-related hormonal interference. That's where this first step of the F.A.S.T. Method comes in.
Metformin is selectively prescribed in the F.A.S.T. protocol based on BMI and metabolic markers. It is not part of every patient's plan — and that's intentional. Dr. Aimee reviews your intake form individually and only prescribes metformin when the clinical picture supports it. If it's not indicated for you, it won't be included.
For those who do need it, metformin works by reducing excess insulin, which can interfere with hormone signaling and egg maturation. The result is improved follicle development and better ovulation quality from the very start of your cycle.
This kind of clinical precision is core to how the F.A.S.T. Method works. Rather than applying a one-size-fits-all supplement regimen, Dr. Aimee is making a real, individualized decision about your specific biology — before your cycle even begins.
A — Assisted Ovulation
Even when you think you're ovulating, subtle hormonal imbalances can mean your follicles aren't maturing fully or you're not releasing a healthy egg reliably each cycle. The F.A.S.T. Method addresses this directly with Letrozole — the same oral medication used in fertility clinics to stimulate ovulation.
Letrozole is an aromatase inhibitor that works by temporarily lowering estrogen levels, which signals your brain to produce more FSH and recruit stronger, more mature follicles. Taken nightly from Cycle Day 3 to Cycle Day 7, it helps your body ovulate more reliably — even when hormonal imbalances have been quietly working against you.
This is a real prescription medication, not a supplement. Dr. Aimee prescribes it based on your intake form, and it ships from CostPlus pharmacy before your cycle begins — so when it's time to take it, it's already at your door. No clinic visits, no waiting rooms, no delays.
Ovulation problems are the leading cause of infertility — and simple ovulation induction treatment with medications taken at home can be a low-cost way to fix ovulation issues, with effectiveness comparable to IVF for addressing ovulation-related issues. The F.A.S.T. Method puts this same clinical intervention in your hands, at home.
S — Support Implantation
Getting pregnant isn't just about releasing an egg. After ovulation, your body needs to produce enough progesterone — and sustain it long enough — to prepare the uterine lining and give a fertilized egg a real chance to implant and grow. Without adequate progesterone, even a perfectly timed cycle can fail silently, before you ever miss a period or see a positive test.
Studies show that up to 50% of women — particularly those over 35, those with PCOS or endometriosis, or those who are overweight — have low progesterone after ovulation. This is one of the most common and most under diagnosed contributors to infertility and early pregnancy loss. And without at-home hormone testing, it goes completely undetected.
In the F.A.S.T. Method, progesterone is given to support implantation. You'll start taking it the same night your PdG rise is confirmed in the Proov app, typically around Cycle Day 15 or 16. That is the precise moment your body needs support most: the opening of the implantation window. Rather than estimating based on a calendar, the F.A.S.T. protocol times progesterone to your actual ovulation, confirmed by real hormone data.
Here's what makes this so significant: progesterone supplementation is given to virtually every patient undergoing IVF, because fertility specialists have long understood how critical it is to implantation success. Multiple clinical studies have demonstrated that administering progesterone after ovulation increases live birth rates up to 50%. Yet for couples trying to conceive at home, this intervention is typically withheld until they've been trying unsuccessfully for 12 or more months — or have suffered two or more miscarriages.
The F.A.S.T. Method changes that. Dr. Aimee prescribes progesterone as part of your protocol so it's ready before your cycle begins. You don't have to wait for heartbreak to access the support your body may already need. Think of it as the prenatal vitamin for your uterus — not an afterthought, but a foundation.
T — Time Intercourse Perfectly
All three of the steps above are designed to optimize your biology — but none of it matters if you're not trying at the right moment. The final step of the F.A.S.T. Method is where hormone data becomes daily, confident action.
In just 10 minutes, the Proov app gives you numeric hormone levels using multi-hormone test strips. You dip a strip, scan it with your phone, and the app reads the result instantly — no squinting at lines, no second-guessing. It tracks four hormones across your entire cycle:
-
FSH — your ovarian reserve indicator, showing how your follicles are responding to fertility signals
-
E1G (an estrogen marker) — signals the opening of your fertile window, identifying up to six fertile days per cycle
-
LH — the surge that precedes ovulation, pinpointing your peak fertile days for timed intercourse or insemination
-
PdG (a progesterone marker) — confirms that ovulation actually occurred and that your progesterone is rising to support implantation
Instead of relying on a single LH spike to guess at your timing, you get a complete, real-time picture of your cycle. The app tells you exactly when your fertile window opens, when you ovulate, and when to start progesterone. No calendar math, no wondering if you missed it. Just clear, data-backed guidance — ten minutes a day, entirely at home.
Research shows that women who track their complete hormone cycle get pregnant significantly faster than those who only track the fertile window. And clinically validated PdG monitoring is correlated with a 75% increase in pregnancy rates when hormone patterns are optimized. That's the difference between hoping you timed it right and knowing you did.
How the Program Works in Practice
Dr. Aimee's F.A.S.T. fertility program is a 3-month, at-home, non-invasive program that includes:
-
3 Proov Complete Test Kits — 9 FSH tests and 51 multi-hormone tests to track estrogen, LH, and PdG across three full cycles
-
3 Proov Check Pregnancy Tests — 30 hCG tests for early pregnancy detection
-
Fertility prescription medications — Letrozole, progesterone, and Metformin (when clinically indicated), prescribed by Dr. Aimee and shipped from CostPlus pharmacy before your cycle begins
-
Reproductive Endocrinologist guidance via email — personalized recommendations from Dr. Aimee on intercourse timing and when to start progesterone
-
Proov Customer Support — real human responses within 24 business hours, 7 days a week
Everything flows through the Proov Insight app, which generates a personalized testing protocol based on your unique cycle and delivers your hormone readings in a format that's both actionable and easy to understand. Each morning, the app tells you whether it's a testing day, which test to take, and what your results mean.
Why This Approach Is Backed by Science
The F.A.S.T. Method isn't just logical — it's supported by a growing body of evidence around restorative reproductive medicine, a model of care that addresses the underlying causes of infertility rather than bypassing them.
A peer-reviewed retrospective analysis published in the Journal of Restorative Reproductive Medicine compared outcomes between a restorative reproductive medicine (RRM) clinic and standard IVF registry data from the CDC, SART, and the UK's HFEA. The RRM clinic reported a live birth rate of 40.4%, significantly higher than the 24.4% rate reported for IVF, along with a twin birth rate of just 2.5% compared to 7% for IVF. That matters — multiple pregnancies carry significantly elevated risks for both mother and babies. Research also shows an average preterm birth rate of 8% for restorative reproductive approaches, compared to 14.1% for IVF.
While IVF is often considered the gold standard in fertility treatment, its financial, emotional, and medical burdens are substantial — and many couples discontinue IVF despite having insurance coverage, due to stress or complications. The F.A.S.T. Method offers a meaningful, evidence-backed alternative for couples who want to be proactive before committing to that level of intervention.
Restorative approaches to fertility aim to normalize cycle parameters — including the length and pattern of bleeding, mucus quantity and quality, and luteal phase factors — so patients can clearly see the impact of treatment on their cycles using objective markers like luteal phase length, hormone levels, and identification of the ovulatory event. This is precisely what the F.A.S.T. Method does: it gives you real data on your real cycle so that every clinical decision is grounded in evidence, not guesswork.
On the clinical testing side, Proov Complete is clinically validated technology linked to a 75% increase in pregnancy rates when hormone patterns are optimized. And Proov is the only FDA-cleared at-home diagnostic test to confirm successful ovulation.
Who Is the F.A.S.T. Method For?
The F.A.S.T. Method is designed for anyone who is:
-
Just starting their TTC journey and wants to approach it strategically from day one
-
Trying to conceive for several months without success, looking for clinical answers before a specialist referral
-
Experiencing suspected hormone imbalances like irregular cycles, short luteal phases, or symptoms of low progesterone
-
Over 35 and aware that both time and hormone optimization matter
-
Diagnosed with PCOS, endometriosis, or insulin resistance and looking for a tailored, medicated approach
-
Looking for a less invasive, more affordable option before committing to IUI or IVF
-
A previous IVF patient who wants to understand their cycle more deeply before pursuing another round
It's also worth being clear: the F.A.S.T. Method is not a replacement for medical care if there are structural issues at play — such as blocked fallopian tubes, severe male factor infertility, or anatomical uterine abnormalities. The F.A.S.T. Method is the smart, proactive first step — and if it doesn't result in pregnancy, the hormone data you've generated becomes incredibly valuable clinical information to bring to a specialist.
The Cost Comparison You Need to See
Let's talk numbers — because they matter enormously on this journey.
A single IVF cycle in the United States costs an average of $12,000–$15,000, before medications, monitoring, or additional transfers. In contrast, simple ovulation induction treatment with medications like Letrozole can cost under $300 per cycle — and for women with ovulation-related infertility, it can be just as effective. When you factor in that ovulation problems are the leading cause of infertility, it becomes clear that many couples are jumping to the most expensive option before trying a targeted, affordable, clinically supervised intervention that may work just as well — or better.
Dr. Aimee's F.A.S.T. Method program through Proov starts at $399 for three months of comprehensive testing, expert prescription guidance, and daily app-based support. And it's FSA/HSA eligible.
The math isn't just about dollars. It's about starting with the right step first — and not spending tens of thousands before you've optimized the fundamentals your body may already be signaling it needs.
