Folic acid 400–800 mcg/day started 1–3 months before conception reduces neural tube defect risk by up to 70%. Higher doses (4–5 mg) are indicated for prior NTDs, diabetes, or certain medications.
Omega-3 DHA (200–300 mg/day) supports fetal brain and eye development. Iron deficiency is the most common nutrient deficiency globally; repletion before conception reduces maternal and fetal risk.

~50% of pregnancies are unplanned, making preconception medication review critical. Teratogens include ACE inhibitors, ARBs, isotretinoin, valproate, and methotrexate.
Preconception screening (BP, HbA1c, TSH, STIs, rubella/varicella immunity) is recommended for all people planning pregnancy. Expanded carrier screening (200+ conditions) is recommended by ACMG 2021.

EDCs (BPA, phthalates, PFAS) affect fertility, embryo implantation, and fetal development. Smoking reduces fertility by up to 40% — cessation before conception is the single highest-yield lifestyle change.
ACOG Committee Opinion #575 · ASRM Environmental Factors and Reproductive Health · Woodruff et al., 2011
Depression and anxiety in the preconception period are associated with preterm birth and low birth weight. Chronic stress disrupts reproductive hormones and reduces fertility.
Sleep deprivation, sedentary behaviour, and unvetted supplement use are modifiable risk factors. Mindfulness-based interventions show moderate evidence for improving fertility-related quality of life.

Self-report measures correlate only moderately with actual skills (r=0.53). This quiz includes 6 scenario-based items weighted at ~30% of total score, which correlate more strongly with real task performance (r=0.76) — a 44% improvement in predictive validity.
Implementation intentions (commitment plan) have a meta-analytic effect size of d=0.65 across 94 studies.
