[4] It is also commonly used for testing human donors for sperm donation, and for animals semen analysis is commonly used in stud farming and farm animal breeding.

  3. Azoospermia - Wikipedia

    en.wikipedia.org/wiki/Azoospermia

    Azoospermia is the medical condition of a man whose semen contains no sperm. [1] It is associated with male infertility, but many forms are amenable to medical treatment.In humans, azoospermia affects about 1% of the male population [2] and may be seen in up to 20% of male infertility situations in Canada.

  4. Sperm Chromatin Structure Assay - Wikipedia

    en.wikipedia.org/wiki/Sperm_Chromatin_Structure...

    Sperm Chromatin Structure Assay (SCSA) is a diagnostic approach that detects sperm abnormality with a large extent of DNA fragmentation. [1] First described by Evenson in 1980, the assay is a flow cytometric test that detects the vulnerability of sperm DNA to acid-induced denaturation DNA in situ. [2]

  5. Semen quality - Wikipedia

    en.wikipedia.org/wiki/Semen_quality

    In a non-harmful environment outside the body, such as in a sterile glass container [31] the number of motile sperm decreases by approximately 5–10% [31] per hour. In contrast, in a latex condom, the quality decreases by 60–80% [ 31 ] per hour, rendering the sample unusable in a relatively short time.

  6. Spermatogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatogenesis

    The resulting spermatozoa are now mature but lack motility. The mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule in a process called spermiation. The non-motile spermatozoa are transported to the epididymis in testicular fluid secreted by the Sertoli cells with the aid of peristaltic ...

  7. Asthenozoospermia - Wikipedia

    en.wikipedia.org/wiki/Asthenozoospermia

    Asthenozoospermia (or asthenospermia) is the medical term for reduced sperm motility.Complete asthenozoospermia, that is, 100% immotile spermatozoa in the ejaculate, is reported at a frequency of 1 of 5000 men. [1]

  8. Necrospermia - Wikipedia

    en.wikipedia.org/wiki/Necrospermia

    Necrospermia (or necrozoospermia) is a condition in which there is a low percentage of live and a very high percentage of immotile spermatozoa in semen. [1]Necrospermia is usually confused with asthenozoospermia, which is the inability of the sperm to move even when alive.

  9. Sperm washing - Wikipedia

    en.wikipedia.org/wiki/Sperm_washing

    Sperm washing involves removing any mucus and non-motile sperm in the semen to improve the chances of fertilization and to extract certain disease-carrying material in the semen. Sperm washing is a standard procedure in infertility treatment .
