Crawford's recurring rule is to control what can reasonably be controlled without pretending that every outcome is controllable. The audit starts by removing exposures she describes as harmful, including smoking and marijuana, and by reviewing alcohol, heat exposure, medications, and medical conditions. It then strengthens recovery and metabolic health through sufficient sleep, individualized stress reduction, a less processed and more plant-rich diet, and regular but not extreme exercise. For men, Crawford notes that sperm development takes about 90 days, making a three-month review period biologically relevant. The framework is deliberately not a promise that disciplined habits will cure infertility. Crawford repeatedly says diseases such as PCOS and endometriosis may require clinical intervention even when a person lives healthfully. Its output is a prioritized discussion and habit plan, not a guarantee of pregnancy.

Core principles
- 01You cannot control every fertility outcome
- 02Remove clear avoidable harms before adding complicated interventions
- 03Sleep, stress, food, and movement affect whole-body health
- 04Sperm changes occur on roughly a three-month production cycle
- 05Medical disease still requires medical care
How to run it
- 1
Identify clear avoidable harms
List smoking, marijuana, other drugs, moderate-to-high alcohol intake, and any unreviewed hormone use. Discuss cessation and medication changes with an appropriate clinician.
Pro tip Start with high-confidence, high-impact behaviors rather than buying supplements.
Watch out Do not stop prescribed medication without medical advice.
- 2
Review environmental and heat exposure
Reduce avoidable plastic heating and prolonged daily heat around the testes where practical. Focus on exposures that can actually be changed rather than trying to eliminate the entire environment.
Pro tip Move hot takeaway food to a plate or glass container instead of reheating it in plastic.
Watch out Evidence strength varies by exposure; Crawford notes that many environmental findings come from animal or observational studies.
- 3
Restore daily recovery
Make sufficient sleep a baseline and dedicate about 20 screen-free minutes to a personally effective form of stress release.
Pro tip Choose a calming practice you will repeat, not the one that sounds most virtuous.
Watch out Stress reduction does not mean infertility is caused by insufficient relaxation.
- 4
Simplify food quality
Increase fruits, vegetables, fiber, and minimally processed foods while reducing refined sugar, processed meat, and heavily packaged foods. Keep the change accessible enough to sustain.
Pro tip Use a meatless day or replace some red meat with fish as practical substitutions discussed by Crawford.
Watch out Nutritional studies vary in how they classify food, so avoid treating one association as proof of causation.
- 5
Balance movement and fuel
Exercise regularly without creating a persistent mismatch between energy intake and expenditure. Adjust either inactivity or extreme training according to the person's health and reproductive goals.
Pro tip Crawford presents moderate daily movement as useful for metabolic health and stress coping.
Watch out Absent periods during intense training are a medical signal, not a fitness achievement.
- 6
Reassess with medical context
Review changes over a clinically appropriate period and combine them with testing or treatment where indicated. For sperm, Crawford points to roughly three months as one production cycle.
Pro tip Bring a short exposure, sleep, exercise, and medication log to the appointment.
Watch out Lifestyle optimization cannot reverse every cause of infertility.
In the wild
Illustrative scenario: a man trying to conceive reviews smoking, prolonged hot-tub use, sleep, exercise, and medications with his clinician. He removes the avoidable heat exposure, stops smoking with support, and repeats an ordered semen analysis after a clinically chosen interval covering roughly one sperm-production cycle.
→ The follow-up is based on measured change rather than assuming the habit plan worked.
Illustrative scenario: a person preparing for pregnancy replaces late-night screen time with a consistent sleep window, adds a daily walk, and shifts several meals toward vegetables, fiber, and minimally processed foods while continuing medical evaluation.
→ The person improves controllable health inputs without delaying diagnostic care or expecting guaranteed conception.
Common mistakes
Turning habits into blame
Crawford says people cannot control everything, and she stresses that reproductive disease is not a personal failure.
Optimizing instead of diagnosing
Severe pain, irregular or absent periods, and known conditions require medical assessment rather than a longer self-help experiment.
Chasing every possible toxin
The useful distinction is between exposures a person can reasonably change and background conditions they cannot control.
Is it for you?
Best for
It is best for people preparing for pregnancy or fertility treatment who want to review changeable lifestyle factors with appropriate medical support.
Not ideal for
It is not a substitute for diagnosis, fertility treatment, or prompt care for irregular periods, severe pain, or known reproductive conditions.

“you can't control everything but you should be able control the factors you can”
“you deserve taking 20 minutes every day and dedicating it to something that doesn't have your iPad your cell phone your computer”
