🔬 Pre-Bump Biology  

Phthalates—chemicals hiding in plastics, food packaging, and personal care products—directly sabotage your fertility. They suppress sex-hormone production, disrupt ovulation, impair sperm concentration, and even rewire sperm DNA in ways that can echo across generations. Couples with higher phthalate levels see up to an 18% drop in monthly chances of conceiving.

🧬 Protocol Drop  

Today’s 1-Step Protocol: 

Both partners: eliminate phthalate sources starting today. Switch to glass or stainless steel for food storage and prep, avoid heating food in plastic, and vacuum/dust weekly with a HEPA filter. These simple shifts cut exposure within days—protecting eggs, sperm, and your baby’s future fertility.

📚 Glossary Pop  

Fecundability: A clinical term for the probability of conceiving in a single menstrual cycle. Lower fecundability means fewer chances of pregnancy each month, making even small percentage drops highly significant over time.

Tag your partner and do a “plastic purge” together tonight. Team effort = stronger fertility wins.
