🔬 Pre-Bump Biology  

Lowering sperm DNA fragmentation (SDF) while nudging female endocrine balance is a high-leverage combo. Shorter ejaculatory intervals reduce epididymal oxidative stress—sending in lower-damage sperm that fertilize and develop better. In parallel, daily flaxseed can lengthen the luteal phase and support healthier estrogen metabolism—key for ovulation, implantation, and embryo quality.

🧬 Protocol Drop  

Today’s Allopathic Protocol:
Ejaculate every 24–48 hours through the fertile window. If SDF is elevated or you’re doing ICSI/IUI, add a second ejaculate within 1–3 hours on the key day (ovulation or retrieval). This trades a little volume for lower DNA damage and improved embryo metrics.

Today’s Holistic Protocol:
Take 10–30 g ground flaxseed daily (with meals) and 28–56 g pumpkin seeds for zinc/magnesium. Do this consistently for 12+ weeks. Optional: follow “days 1–14 flax + pumpkin” if you like the rhythm—but the daily pattern is what’s evidence-aligned.

đź“š Glossary Pop  

Sperm DNA Fragmentation (SDF/DFI): A measure of broken DNA strands inside sperm. High SDF is linked to poorer fertilization, embryo quality, and pregnancy outcomes. Reducing storage time between ejaculations lowers oxidative damage and improves SDF.

Forward this to your partner and lock in your cadence + seeds. Conception is a team sport—sync up and win the window.
P.S. Tomorrow Teaser
Tomorrow we’ll dive into the night shift of fertility: how magnesium glycinate (200 mg nightly) resets your sleep–stress axis, and how pairing it with ashwagandha (300 mg/day) can calm cortisol, stabilize hormones, and prime your body for conception.
