1
Jangka Hayat Sperma: Sehingga 5 Hari
Boleh bertahan hidup di dalam cecair serviks yang subur selama 120 jam menunggu telur.
2
Jangka Hayat Telur: 12 hingga 24 Jam
Mesti disenyawakan dalam tempoh 24 jam selepas dilepaskan.
3
Masa Terbaik: 1-2 Hari Sebelum Ovulasi
Bersama 1-2 hari sebelum ovulasi menghasilkan peluang kehamilan tertinggi (~31%).
Tanda Fizikal Tambahan
Perhatikan tanda-tanda semula jadi ini:
Cecair Putih Telur
Sangat kenyal dan jernih ketika estrogen memuncak.
Peningkatan Suhu Tubuh
Suhu badan naik sedikit selepas ovulasi berlaku.
Lonjakan Hormon LH
Jalur ujian positif 24-36 jam sebelum telur dilepaskan.
Soalan Lazim (FAQ)
Jawapan berasaskan bukti perubatan mengenai kitaran haid dan ovulasi
Bagaimanakah kalkulator ovulasi ini berfungsi?
Dengan menolak panjang fasa luteal anda daripada tarikh jangkaan haid seterusnya.
Apakah tempoh subur dan bilakah masa terbaik bersama?
5 hari sebelum ovulasi dan hari ovulasi. Paling baik ialah 1-2 hari sebelum ovulasi.
Bolehkah digunakan jika haid saya tidak teratur?
Boleh! Mod Kitaran Tidak Teratur mengira julat subur yang lebih luas mengikut rekod anda.
Bilakah ujian kehamilan boleh dibuat?
Sekitar 12-14 hari selepas ovulasi atau pada hari pertama kelewatan haid.
Mengapakah alat ini lebih tepat?
Menyokong pelarasan fasa luteal, kitaran tidak teratur dan data kebarangkalian harian.
Adakah data peribadi saya selamat?
Ya, 100%. Semua pemprosesan dilakukan dalam pelayar anda tanpa disimpan di pelayan luar.

Clinical Methodology & Medical References
The algorithmic models powering Free Ovulation Tracker are grounded in established gynecological physiology and peer-reviewed reproductive science.
📅 Follicular & Luteal Phase Modeling
Standard clinical calendar models assume an invariant 14-day luteal phase. However, physiological research published by theAmerican College of Obstetricians and Gynecologists (ACOG) — Evaluating Infertility & Ovulationdemonstrates that healthy luteal phases range between 10 and 17 days. Our calculation algorithm enables individual luteal duration calibration (defaulting to 14 days) to accurately back-calculate ovulation day: Ovulation Day = Cycle Length - Luteal Phase.
🔬 The 6-Day Fertile Window (Wilcox Study)
The biological fertile window spans precisely six days: the five days preceding ovulation plus ovulation day itself. In the landmark clinical study published in theWilcox et al., New England Journal of Medicine (NEJM), researchers demonstrated that viable sperm can survive up to 5 days in estrogenic cervical mucus, while the unfertilized oocyte remains viable for 12–24 hours post-follicular rupture.
⚡ LH Surges & Ovulation Prediction
Luteinizing Hormone (LH) surges 24–36 hours prior to follicular rupture, prompting final oocyte maturation. Our platform integrates secondary biomarker guidance in alignment withNational Institutes of Health (NIH/PubMed)findings, advising users to pair calendar predictions with urine ovulation predictor kits (OPKs) for pinpoint accuracy during irregular cycles.
🌡️ BBT Thermal Shifts & Cervical Mucus
Progesterone secretion from the corpus luteum elevates Basal Body Temperature (BBT) by 0.5°F–1.0°F (0.3°C–0.6°C) within 48 hours post-ovulation, confirming release retrospectively. In accordance withWorld Health Organization (WHO)reproductive protocols, tracking fertile "egg-white" cervical mucus (spinnbarkeit) provides real-time confirmation of maximum conception probability.
