Natural Check Male Fertility Test

Natural Check Male Feritility Test is a rapid test for qualitative detection of sperm concentraction in human semen, as an aid in the determination od a man's fertility status.

How does it work?

SP10 is a protein that only expressed in testis and has been verified as an analyte for Sperm Concentration test. The concentration of SP10 is proportion to the concentration of sperm. When the sperm concentration is more than 15x10/ml, the result is positive. This sperm concentration test can be use as an aid in diagnosis and treatment abservation of male infertility.

When the sample is added into the specimen well, capillary action carries the specimen to migrate along the mambrane. When the sperm levels in specimens are at or above the target cutoff, there is a visible colored band in the Test Region (T) and indicates a positive result. Absence of this colored band in the (T) suggests a negative result.

How to use



Wait at least 48 hours, but no more than seven days after your last ejaculation.


  1. Wash your hands and genitals with soap.
  2. Collect your semen sample by manual stimulation (masturbation), in the semen collection cup provided.
  3. Ejaculate directly into the semen collection cup provided without losing any portion of the semen. Do not use a condom to collect the sample. (If you do lose any semen, discard the sample, rinse the cup with tap water only and let it air dry before using it again. Do not use soap or detergent to wash the cup. Wait at least 48 hours, but no more than seven days to collect a new semen sample.)
  4. After collecting the sample. Let the cup stand upright on a flat surface.
  5. Sample may be tested up to 3 hours after collection. Discard sample if not tested within 3 hours and wait at least 48 hours to obtain fresh sample to test.
  6. When you are ready to test, follow the instructions in the next section, ‘HOW TO DO THE TEST’.


  1. Gently shake the collection cup with semen then let the sample stand for at least twenty (20) minutes, but no more than 60 minutes for the semen to become thin (liquefied) before testing. (The semen sample is too thick for test immediately after ejaculation).
  2. Gently stir the sample in the collection cup with a semen transfer device for 10 times.
  3. Unscrew the cup of the solution bottle. Pull plunger of transfer device to draw semen up to raised frosted line (0.1ml). Transfer 0.1ml of the sample in to the solution bottle, avoid any bubbles.
  4. Screw the cup of solution bottle tightly and gently mix the sample thoroughly. It’s recommended to turn the solution bottle upside down for 5 to 10 times.
  5. Let the solution bottle stand for 2 minutes.
  6. Remove the testing cassette for the sealed pouch by tearing at the notch and place the testing cassette on a flat surface.
  7. Unscrew the smaller cup of the solution bottle, and add 2 full drops of the semen sample on the sample well of the cassette vertically.
  8. Wait for 5 to 10 minutes and read the results.
  9. Do not read results before 5 minutes or after 10 minutes.


Positive (+)

Coloured bands are visible in both the control region (C) in the test region (T). It indicates a positive result (The sperm concentration is below 15x10/ml).

Negative (-)

A coloured band is visible only in the control region (C). No colour band appears in the test region (T)

It indicates a negative results (The sperm concentration under 15x10/ml).


No visible band at both region, or there is a visible band only in the test region but not in the control region. Repeat with a new test cassette. Please make sure the adding sample volume is enough. If the test still fails, please contact or the distributor for technical assistance.


  1. This test is just for preliminary screening of the sperm concentration. The test result should be evaluated with other clinical and laboratory data available. If the test results do not agree with the clinical evaluation, additional tests should be performed.
  2. The test is just for qualitative detection, for quantitative detection, medical professional test is suggested.
