The three to six months before beginning ICI are one of the highest-leverage periods of the fertility journey — a window during which foundational choices about nutrition, lifestyle, medical preparation, and emotional readiness compound in ways that pay dividends through every subsequent cycle. This checklist covers everything worth doing before your first attempt.
Medical and Screening Priorities
Complete a preconception medical visit with your OB-GYN or primary care provider covering: immunization status (confirm rubella and varicella immunity — these infections during pregnancy carry significant fetal risk; vaccination requires at least one month before conception), cervical cancer screening if due, STI screening including HIV and hepatitis B/C, blood type and Rh factor (Rh-negative individuals need Rh immunoglobulin during pregnancy if exposed to Rh-positive blood), and a general physical exam to identify any health conditions that should be addressed before pregnancy. This visit is distinct from a fertility evaluation — it is the general health foundation that supports a healthy pregnancy once conception occurs.
Order or request a baseline fertility panel: AMH (any cycle day), day-3 FSH and estradiol (cycle days 2–5), TSH (any day), prolactin (morning, fasting), and Vitamin D (25-OH-D). If you have a male partner, add semen analysis to the list. These tests provide the biological context for protocol decisions and, crucially, identify any treatable conditions before the first ICI cycle rather than mid-journey. A Vitamin D level below 30 ng/mL — found in approximately 40% of reproductive-age Americans — is correctable with supplementation and its correction may improve implantation rates. TSH above 2.5 mIU/L may be treated with low-dose levothyroxine before cycling.
Nutritional and Supplement Preparation
Begin a prenatal vitamin containing 400–800 mcg of folate (methylfolate is preferable to folic acid for individuals with MTHFR gene variants, which affect approximately 40% of the population) at least three months before beginning ICI. Folate is critical for neural tube development in the first weeks after conception — before most people know they are pregnant — making pre-conception supplementation essential. Omega-3 fatty acids (at least 1–2g DHA/EPA daily from fish oil or algae-based supplement) support cell membrane quality in both eggs and sperm and reduce inflammatory markers associated with poor fertility outcomes.
Additional supplements with evidence for preconception support include: CoQ10 (400–600 mg daily as ubiquinol) to support mitochondrial function in oocytes, particularly for women over 35 where age-related mitochondrial decline in eggs is established; vitamin D (2000–4000 IU daily, adjusted for baseline level and weight); inositol (2–4g daily, particularly for PCOS patients where it improves insulin sensitivity and ovulatory function); and magnesium glycinate (300 mg daily, associated with cycle regularity and sleep quality that supports hormonal function). Begin all supplements three months before your first ICI cycle to allow full physiological integration across the spermatogenesis or oogenesis timeline.
Lifestyle Preparation
Alcohol: the evidence on alcohol’s impact on fertility is dose-dependent. Heavy alcohol use (more than 14 drinks per week) is clearly associated with reduced conception rates and increased miscarriage risk. Moderate use (7–14 drinks per week) has equivocal evidence. For preconception preparation and certainly during any ICI cycle, limiting alcohol to fewer than 7 drinks per week — with complete abstinence during the two-week wait when implantation may be occurring — is the conservative and evidence-aligned approach. Complete abstinence is the safest choice and is recommended by ACOG during known pregnancy.
Caffeine: consumption above 200 mg per day (approximately two cups of coffee) is associated with modestly increased miscarriage risk in some studies. Reducing to below 200 mg per day (one to two cups of regular coffee) is a reasonable preconception target that does not require complete elimination for most people. Body weight: both underweight (BMI below 18.5) and overweight (BMI above 30) are associated with hormonal disruption that impairs ovulatory function. Achieving a BMI of 18.5–29.9 before beginning ICI cycles, through sustainable dietary and exercise changes rather than crash intervention, improves hormonal environment and per-cycle odds. Exercise: regular moderate aerobic exercise (150 minutes per week of moderate-intensity activity) is associated with better hormonal profiles and reduced stress hormones; high-intensity exercise (more than 60 minutes of vigorous activity daily) is associated with hypothalamic suppression in lean women and is worth moderating during the preconception period.
Mental and Emotional Preparation
Mental preparation before beginning ICI involves two distinct components: information preparation (understanding your cycle, the ICI process, likely timelines, and what the decision points along the journey are) and emotional preparation (building the resilience infrastructure that allows you to navigate disappointment without crisis). The information component is addressed by resources like this guide. The emotional component requires active construction of support systems, stress management practices, and an honest assessment of your readiness to navigate uncertainty across multiple cycles.
Establishing a mental health provider before beginning ICI is strongly recommended — not because you expect to need crisis support but because having a therapist who knows your story and your baseline makes accessing support during difficult moments far easier than finding a new therapist in the middle of a hard cycle. Similarly, identifying the two to three people in your personal life who will constitute your fertility support circle — people you trust to ask for specific support, not to give unsolicited advice — and having an explicit conversation with them about what support from them looks like gives you a human network to draw on before you need it. The support infrastructure built in advance of difficulty is almost always more reliable and more effective than the support assembled in response to it.
