What Are Fertility Tests?

Fertility tests help identify key biological markers that influence the ability to conceive.

At RapidTest.co, our at-home fertility range includes quick, lab-free tests designed for both men and women — helping couples understand their reproductive health before seeking clinical support.

These tests are ideal for couples trying to conceive, monitoring hormone cycles, or simply checking reproductive wellness from the privacy of home.

Other Common STI Tests
  • SP-10 Male Fertility Test (Sperm Concentration Test)

    Purpose:
    The SP-10 test checks the concentration of sperm proteins (SP-10 antigen), which directly correlates with sperm count and fertility potential.

    How it works:

    • Collect a semen sample using the included sterile container.
    • Mix it with the reagent as directed.
    • Apply a few drops to the test cassette.
    • Results appear within 10–15 minutes.

    What results mean:

    • Two lines: Normal sperm concentration (fertile range)
    • One line: Low sperm concentration (possible infertility risk)

    ✅ CE-marked & ISO-certified
    ✅ More than 95% accuracy
    ✅ Gives peace of mind without the clinic visit

  • LH Ovulation Test (Luteinising Hormone)

    Purpose:
    The LH test helps track ovulation by detecting a surge in luteinising hormone in urine — which occurs 24–36 hours before ovulation.

    This helps identify the most fertile days in a woman’s cycle.

    How it works:

    • Use the test daily around your predicted ovulation window.
    • Dip the test strip in urine for a few seconds.
    • Wait 5 minutes and read the result.

    What results mean:

    • Two lines (C + T): LH surge detected — ovulation is imminent.
    • One line (C): No LH surge — not in ovulation window.

    ✅ Accurate cycle tracking
    ✅ Easy for daily use
    ✅ Helps time intercourse for conception

    • Rash on the body, palms or soles
    • Swollen lymph nodes or fever
    • Fatigue or patchy hair loss

  • HCG Pregnancy Test

    Purpose:
    The HCG test detects human chorionic gonadotropin (hCG) — a hormone produced after conception.

    It confirms pregnancy with over 99% accuracy from as early as the first day of a missed period.

    How it works:

    • Dip the test strip or midstream cassette in urine.
    • Wait 3–5 minutes.
    • Read the result.

    What results mean:

    • Two lines: Positive (pregnant)
    • One line: Negative (not pregnant)

    ✅ Over 99% accuracy
    ✅ CE-marked for home use
    ✅ Clear, fast, and reliable results
