🔬 Pre-Bump Biology  

Two levers move fast: heat and ultra-processed food (UPF). Short sauna exposures can disrupt spermatogenesis for weeks, while one home-cooked meal begins dropping EDCs (phthalates/bisphenols) within 24–48 hours. Together, skip heat, cook clean—to protect sperm DNA integrity, ovarian quality, and time-to-pregnancy.

🧬 Protocol Drop  

Today’s Allopathic Protocol:
Men in the 90-day pre-conception window: avoid sauna/hot tubs/steam (≥70–90 °C) for 90 days. If any heat exposure occurs, book a semen analysis at week 10 to check count, motility, and DNA integrity. Do sessions only after conception attempts are paused.

Today’s Holistic Protocol:
Tonight, cook at home. Build a low-EDC, Mediterranean-style plate: ½ plate vegetables, ¼ legumes/whole grains, ¼ fish/chicken/tofu; 30 g nuts; moist-heat methods (stew/steam). Eat on a 10–12-hour daytime window, finish 3–4 h before bed. Repeat daily for 90 days.

📚 Glossary Pop  

Endocrine-disrupting chemicals (EDCs): Industrial chemicals (like phthalates and bisphenols) that leach from food packaging and processing. They can mimic or block hormones, disturbing the HPG axis and steroid production—hurting sperm quality and ovarian function. Switching to minimally packaged, home-cooked meals cuts exposure fast.

Cook dinner together tonight and make a pact: no sauna for 90 days. Conception is a team sport.
