SEMENALYSIS

• paired glands in the scrotum that contain seminiferous tubules for secretion of sperm.

  Testes
• is composed of FOUR fractions contributed by the testes, epididymis, seminal vesicles, prostate gland, and bulbourethral glands.

  Semen
• The sperm remains in the ____ until ejaculation, at which time they are propelled through the ductus deferens (vas deferens) to the ejaculatory ducts.

  epididymis
• Germ cells for the production of spermatozoa are located in the ____

  epithelial cells of the seminiferous tubules
• Specialized _____ provide support and nutrients for the germ cells as they undergo mitosis and meiosis (spermatogenesis)

  Sertoli cells
• When spermatogenesis is complete, the IMMATURE sperm (nonmotile) enter the ____.

  epididymis
• The _____ receive both sperm from the ductus deferens and fluid from the ______.

  ejaculatory ducts

  seminal vesicles
• The ______ produce most of the fluid present in the specimen (__% - __%)

  seminal vesicles

  60-70%
• The fluid contains high concentrations of ____ and ____

  fructose

  flavin
• _____ metabolize fructose for the energy needed for the flagella to propel them through the female reproductive tract.

  Spermatozoa
• In the absence of fructose, sperm do not display motility in the semen analysis (True or False) 


  True
• Flavin is responsible for the ___ appearance of semen, as well as the ___ to ___ fluorescence when semen is visualized under ultraviolet light (Wood’s lamp)

  gray

  blue-yellow
• located just below the bladder, surrounds the upper urethra and AIDS in PROPELLING the sperm through the urethra by contractions during ejaculation. 


  PROSTATE GLAND
• Approximately __ - __% of the semen volume is ACIDIC fluid produced by the prostate gland.

  20-30%
• The milky acidic fluid contains high concentrations of:

  Acid phosphatase, Citric acid, Zinc, Proteolytic enzymes
• Located below the prostate Contributes to 5% of the fluid volume in the form of THICK, ALKALINE mucus

  Bulbourethral Glands
• Helps NEUTRALIZE acidity from the prostate secretions and the vagina

  Bulbourethral Glands
• It is important for the semen to be ALKALINE to NEUTRALIZE the VAGINAL ACIDITY present as a result of normal bacterial vaginal flora (true or false)

  TRUE
• Function of Seminiferous tubules of testes:

  Spermatogenesis
• Function of Epididymis: 


  Sperm maturation
• Provide nutrients for sperm and fluid

  Seminal vesicles
• Propel sperm to ejaculatory ducts

  Ductus deferens
• Provides enzymes and proteins for coagulation and liquefaction

  Prostate gland
• Add alkaline mucus to neturalize prostatic acid and vaginal acidity

  Bulbourethral glands
• is a surgical procedure that involves the cutting of the vas deferens

  Vasectomy
• In medicolegal cases to establish a case what are the components of semen is involved

  Spermine

  choline

  Acid phosphatase
• Provide energy to the sperm cell

  Fructose
• Components of Semen


  Spermine and choline

  Acid phosphatase Fructose

  Potassium and Citric Acid Zinc Ergothionine Phosphorylcholine Proteolytic enzyme
• Very important component of semen If this is absent, this is a sign of infertility

  Proteolytic enzyme
• Produced by male animals and hermaphrodites (sperm/semen)

  semen
• Produced by both animals and plants (sperm/semen)

  sperm
• A microscopic cell that contains an oval-shaped head with a long tail (sperm/semen)

  sperm
• A viscous liquid, which is typically whitish-gray in color (sperm/semen)

  semen
• Liquid carrier of sperms (sperm/semen)

  semen
• Semen is the reproductive fluid of males, which contains sperms in suspension (sperm/semen) 


  semen
• is a male reproductive cell (sperm/semen)

  sperm
• Only cellular component of the semen (sperm/semen)

  sperm
• Not visible to the naked eye (sperm/semen)

  sperm
• Carries sperms while nourishing them and keeping their mobility (sperm/semen)

  semen
• Visible to the naked eye (sperm/semen)
