🔬 Pre-Bump Biology  

Nicotine drives oxidative stress and epigenetic damage in eggs and sperm, elevating sperm DNA fragmentation and depressing ovarian reserve. Slow, exhale-emphasized breathing (e.g., 4-7-8) calms the HPA axis and boosts vagal tone—lowering stress signals that disrupt ovulation, implantation, and seminal redox balance. Today, you’ll cut nicotine and install a daily autonomic reset to protect embryo potential.

🧬 Protocol Drop  

Today’s Allopathic Protocol:
Quit all nicotine (cigarettes, vapes, pouches) today. If not pregnant, start varenicline: 0.5 mg QD (days 1–3) → 0.5 mg BID (days 4–7) → 1 mg BID through week 12; take with food/water. Use contraception until 7–8 days after the last dose. Baseline labs: Men—semen analysis ± SDF; Women—AMH/FSH. Re-test at ~12 weeks.

Today’s Holistic Protocol:
Perform 5–10 minutes of slow nasal breathing twice daily for 8–12 weeks. Prefer ~6 breaths/min (inhale ~4 s, exhale ~6 s) or gentle 4-7-8 (avoid straining holds). Best timing: 30–60 min after waking and early evening. Optional: soft humming on exhale 1–2×/week.

📚 Glossary Pop  

Sperm DNA Fragmentation (SDF): A measure of DNA breaks in sperm. High SDF impairs fertilization, embryo development, and live-birth odds. Quitting nicotine and improving redox balance can reduce SDF over one spermatogenic cycle (~74 days).

Forward this protocol to your partner—make quitting and breathing a shared daily reset. Fertility is team biology.
