Semen Fructose Test. Fructose level in the semen may be analysed to determine the amount of energy available to the semen for moving. [6] WHO specifies a normal level of 13 μmol per sample. Absence of fructose may indicate a problem with the seminal vesicles. The semen fructose test checks for the presence of fructose in the seminal fluid.

A 1992 World Health Organization report described normal human semen as having a volume of 2 mL or greater, pH of 7.2 to 8.0, sperm concentration of 20×10 6 spermatozoa/mL or more, sperm count of 40×10 6 spermatozoa per ejaculate or more, and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid ...
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml). This is the most common type of fertility testing.
The postcoital test (PCT), also known as the Sims test, Hühner test ,Sims–Hühner test, or cervical mucous penetration assay is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix .
Hypospermia is a condition in which a man has an unusually low ejaculate (or semen) volume, less than 1.5 mL.It is the opposite of hyperspermia, which is a semen volume of more than 5.5 mL. [1]
Sperm may be washed by density gradient centrifugation or by a "direct swim-up" technique that does not involve centrifugation. In normal semen samples, centrifugation causes no more DNA damage to spermatozoa than a direct swim-up technique. [2] Washed sperm is concentrated in Ham's F-10 media without L-glutamine, warmed to 37 °C (99 °F). [3]
Since the test is performed with fresh semen and the incubation requires only 10 minutes, it renders MAR test a quick and simple screening tool for ASA in human ejaculate. However, samples with very low sperm count (i.e. severe oligoastheno-, or even azoospermia) cannot be evaluated using this method. Also presence of debris or high viscosity ...
