THE 6-DAY BIOLOGICAL FERTILE WINDOW

Peak Days: O-2 & O-1 (58% Total Odds)
Day O-5 Low ~10% Sperm enters
Day O-4 Medium ~16% Mucus rising
Day O-3 High ~14% Follicle ~16mm
Day O-2 Peak ~27% Prime Day 🔥
Day O-1 Top Odds ~31% LH Surge Peak
Ovulation Release ~12% Egg Viable 12-24h
Day O+1 Closed ~0-2% Progesterone rise
Sperm Survival Span: Up to 120 hours (5 days) nourished in cervical crypts
Egg Longevity: 12-24 hours max post-LH rupture

  • Sperma: Bertahan hingga 120 jam dalam lendir serviks yang subur dan kaya nutrisi.
  • Sel Telur: Hanya dapat dibuahi selama 12–18 jam setelah pelepasan dari folikel.
  • Kapasitasi: Sel sperma memerlukan 5–10 jam dalam saluran reproduksi wanita agar mampu menembus sel telur.

§ 2. Probabilitas Harian (Studi Wilcox)

  • Hari H-2: ~27%
  • Hari H-1: ~31% (Peluang Tertinggi)
  • Hari Ovulasi: ~12%
