  2. Sperm motility - Wikipedia

    en.wikipedia.org/wiki/Sperm_motility

    The change in cell volume which alters intracellular ion concentration can also contribute to the activation of sperm motility. In some mammals, sperm motility is activated by increase in pH, calcium ion and cAMP, yet it is suppressed by low pH in the epididymis. The tail of the sperm - the flagellum - confers motility upon the sperm, and has ...

  3. Semen analysis - Wikipedia

    en.wikipedia.org/wiki/Semen_analysis

    A routine semen analysis should include: physical characteristics of semen (color, odor, pH, viscosity and liquefaction), volume, concentration, morphology and sperm motility and progression. To provide a correct result it is necessary to perform at least two, preferably three, separate seminal analyses with an interval between them of seven ...

  4. Semen quality - Wikipedia

    en.wikipedia.org/wiki/Semen_quality

    Collecting the sperm at home gives a higher sperm concentration, sperm count and motility, particularly if the sperm is collected via sexual intercourse. [36] If the semen sample is to be collected by masturbation, a specimen from the early stages of the ejaculate should be into a clean, unused, sealed collection cup.

  5. Male infertility - Wikipedia

    en.wikipedia.org/wiki/Male_infertility

    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.

    en.wikipedia.org/wiki/Artificial_insemination

    c is the concentration of motile sperm in a sample after freezing and thawing, approximately 5–20 million per ml but varies substantially; r s is the pregnancy rate per cycle, between 10% and 35% [39] n r is the total motile sperm count recommended for vaginal insemination (VI) or intra-cervical insemination (ICI), approximately 20 million pr ...

    en.wikipedia.org/wiki/Semen

    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 ...
