What Is Restorative Reproductive Medicine?
Restorative reproductive medicine — RRM for short — is an approach to infertility treatment built on a simple premise: instead of creating embryos in a lab to work around the problem, find and fix the problem itself so the couple can conceive naturally.
Arkansas law defines it as "a scientific approach to reproductive medicine that seeks to cooperate with or restore the normal physiology and anatomy of the human reproductive system without the use of methods that are inherently suppressive, circumventive, or destructive to natural human functions."
In practice, RRM involves detailed diagnostic workups to identify specific causes of infertility, followed by targeted treatments. The most established RRM protocol is NaProTechnology (Natural Procreative Technology), developed by Dr. Thomas Hilgers at the Pope Paul VI Institute in Omaha, Nebraska.
What Does RRM Treatment Actually Look Like?
Detailed Cycle Charting
Patients learn to chart their menstrual cycles using a fertility awareness-based method — usually the Creighton Model FertilityCare System. This involves daily tracking of cervical mucus patterns to identify hormonal function, cycle irregularities, and potential problems.
Targeted Hormonal Testing
Rather than generic blood panels, RRM practitioners use cycle charting data to time hormonal tests precisely — measuring progesterone, estrogen, LH, FSH, and other hormones at specific points in the cycle to identify exactly where the dysfunction lies.
Diagnosis of Underlying Conditions
RRM emphasizes thorough diagnostic workups. Common findings include endometriosis (treated surgically), PCOS (treated with targeted medications), luteal phase defects (treated with progesterone), thyroid disorders, hormonal imbalances, and structural issues like polyps or fibroids.
Targeted Treatment
Treatments vary by diagnosis: surgical excision of endometriosis, hormonal supplementation (progesterone, hCG, clomiphene), thyroid medication, cycle-timed intercourse based on charting data, and lifestyle modifications. The goal is to restore normal reproductive function so conception happens naturally.
RRM isn't "just track your cycle and hope for the best." The surgical and hormonal components can be significant — laparoscopy for endometriosis, hysteroscopy for uterine issues, targeted pharmaceutical interventions. The diagnostic workups are genuinely thorough. What distinguishes RRM from standard fertility care is not the absence of medical intervention, but the insistence that intervention should restore natural function rather than bypass it.
What Does the Evidence Show?
The honest answer: the RRM evidence base is growing but still has significant gaps.
The Supporting Data
The largest study to date, published in 2025 by Sanchez-Mendez and colleagues, followed 1,310 couples treated with NaProTechnology over five years. The crude take-home baby rate was 35.3%, with an adjusted cumulative rate of 62.1%. Success varied significantly by age: 83.7% for women aged 18-30, 53.3% for ages 36-40, and 24.4% for women over 40.
A separate 2025 study from NeoFertility Dublin (Boyle et al.) reported a 41% crude live birth rate in 187 couples, with a mean time to conception of approximately 12 months. Earlier studies from Canadian family practices showed similar results — one reported a 66% cumulative live birth rate using NaProTechnology protocols.
The Limitations
Critics — including the American Society for Reproductive Medicine (ASRM) and the American College of Obstetricians and Gynecologists (ACOG) — raise serious concerns about the evidence base:
- No randomized controlled trials. Every published RRM study is observational. There has never been a head-to-head trial randomizing patients to RRM versus standard fertility care or IVF. Without this, claims about comparative effectiveness are speculative.
- Dropout bias. The "adjusted" cumulative rates assume that patients who dropped out of treatment would have had the same success rate as those who stayed — a potentially optimistic assumption. The crude rates (35-41%) tell a more conservative story.
- Selection bias. Patients who seek out RRM may differ systematically from those who pursue IVF — in age, diagnosis, severity of infertility, or motivation. Without randomization, these differences confound the results.
- Time cost. RRM treatment typically takes 6-18 months. For women over 35, every month matters. A year spent on RRM that doesn't work is a year of additional egg quality decline.
The Political Context You Need to Understand
RRM cannot be fully understood without acknowledging its political dimension — and as a patient, you deserve to know about it.
In 2025, Arkansas passed the RESTORE Act (Reproductive Empowerment and Support Through Optimal Restoration), becoming the first state to mandate insurance coverage for RRM. The legislation was supported by conservative organizations including the Heritage Foundation and the Ethics & Public Policy Center. Similar bills have been introduced in Minnesota, South Carolina, and at the federal level.
Many RRM practitioners are Catholic, and the approach is endorsed by Catholic bioethics organizations because it aligns with Church teachings that oppose IVF (due to the creation and potential destruction of embryos outside the body). The Pope Paul VI Institute — where NaProTechnology was developed — is a Catholic institution.
This doesn't automatically invalidate the medical approach. Good medicine can come from any philosophical framework. But it does mean patients should be aware of two things:
- Some RRM practitioners may not fully disclose their philosophical position on IVF, and some may be unwilling to refer patients to reproductive endocrinologists if RRM doesn't work. An ASRM roundtable noted this is "extremely worrying" and compared some RRM-only clinics to crisis pregnancy centers in terms of limited disclosure.
- The legislative push for RRM is, in the view of many fertility specialists, not just about expanding access to RRM — it's also about creating a framework that could be used to restrict access to IVF. Arkansas RE Dr. Dean Moutos described the RESTORE Act as a "backhanded attack on assisted reproductive technology."
Both Sides: A Fair Assessment
✅ What RRM Gets Right
- Emphasizes thorough diagnostic workups — some standard fertility practices do jump to IVF before fully evaluating treatable conditions
- Many individual components (endometriosis surgery, hormonal testing, thyroid treatment) are evidence-based and widely accepted by mainstream medicine
- Less physically invasive than IVF — no egg retrieval, no hormonal stimulation protocols
- Significantly less expensive than IVF cycles ($3,000-$8,000 vs. $15,000-$25,000)
- Treats whole reproductive health, not just the immediate goal of pregnancy
- Insurance coverage for RRM diagnostics and surgery benefits all patients, regardless of their position on IVF
⚠️ What Critics Are Right About
- No randomized controlled trials comparing RRM to standard care or IVF — the evidence base has real gaps
- Cannot address many common causes of infertility: bilateral tubal blockage, severe male factor, age-related egg quality decline, or genetic factors
- The time cost (6-18 months) can be devastating for women over 35 whose fertility is actively declining
- Some practitioners' refusal to refer to REIs can delay patients from getting effective treatment
- Political framing as an "alternative to IVF" rather than a complement to it can restrict patient choice
- Reported success rates may be inflated by dropout assumptions and selection bias
Who Might Benefit From RRM?
Here's where nuance matters more than ideology:
- Couples early in their fertility journey — particularly women under 35 — may benefit from a thorough RRM-style diagnostic workup before jumping to IVF. If endometriosis, PCOS, or a hormonal imbalance is the issue, targeted treatment could resolve it.
- Patients with "unexplained infertility" — RRM's emphasis on finding root causes can sometimes identify treatable conditions that a standard workup missed.
- Couples who have religious or ethical objections to IVF — RRM provides a legitimate medical framework for pursuing fertility treatment within those beliefs.
- Women with recurrent pregnancy loss — the diagnostic approach can uncover hormonal and structural issues contributing to miscarriage.
RRM is less likely to help in cases of severe tubal disease, significant male factor infertility (very low sperm count or quality), advanced maternal age with diminished ovarian reserve, or couples who have already had thorough evaluations without identifiable treatable conditions.
What to Ask Any Fertility Provider
Whether you're seeing an RRM practitioner or a reproductive endocrinologist, these questions help ensure you're getting balanced care:
- "What is your diagnostic process before recommending treatment?" — Both good RRM practitioners and good REIs should do thorough evaluations before jumping to any intervention.
- "If this approach doesn't work within [timeframe], what's next?" — A provider unwilling to discuss alternative approaches, including IVF, may not be giving you the full picture.
- "Do you refer to reproductive endocrinologists when appropriate?" — Any practitioner who won't refer is limiting your options.
- "What are the success rates for patients with my specific diagnosis, at my age?" — General success rates don't tell you your odds. Condition-specific, age-specific data matters.
- "What's the time cost of this approach, and how does that interact with my age?" — Especially important for women 35 and older.
Know All Your Options

Explore Treatment Options →The Bottom Line
Restorative reproductive medicine, at its best, represents something the fertility field actually needs more of: thorough diagnostic workups, treatment of root causes, and respect for the body's natural function. Many individual components of RRM — endometriosis surgery, hormonal optimization, detailed cycle analysis — are good medicine by any standard.
The problem is when RRM is positioned as an alternative to IVF rather than a complement to it. Not all infertility has a "fixable" root cause. Not all patients have months to spare. And not all RRM practitioners are transparent about the ideological framework behind their practice.
The ideal fertility care system would give every patient access to both approaches: thorough diagnostic evaluation and root-cause treatment (the best of RRM), plus the full spectrum of assisted reproductive technologies (IVF, IUI, egg/embryo freezing) when those treatments are needed. That's what being truly "patient-centered" looks like.
Whatever path you choose, make sure your provider is giving you the full picture — not just the options that align with their personal philosophy.
