A

clumped and highly viscous.

27

  • And forms small discrete droplets, without appearing clumped or stringy.
28
Q

When do droplets in a fluid specimen form longer than 2cm, and what does it indicate?

A
  • It indicate highly viscous fluid and may suggest an abnormality in enzyme function.
29
Q

  • Typically indicates the presence of an infection.
31
Q

What can a decreased pH in the reproductive tract be associated with?

A
  • Can be associated with increased prostatic fluid, ejaculatory duct obstruction, or poorly developed seminal vesicles.
32
Q

What is the role of prostatic fluid in the acidity of semen?

A
  • Contains substances or enzymes responsible for the acidity of semen
33
Q

What is considered a normal sperm concentration range?

A
  • Typically greater than 20 to 250 million sperm per milliliter.
34
Q

What is the range for borderline sperm concentration?

A
  • It falls in the range of 10 to 20 million sperm per milliliter.
35
Q

How is sperm count calculated?

A
  • Sperm count is calculated by multiplying sperm concentration by specimen volume.
36
Q

What is considered a normal sperm count?

A
  • Generally greater than 40 million per ejaculate.
37
Q

How is sperm cell counting performed using the WBC pipet?

A
  • With a dilution ratio of 1:20, achieved by aspirating semen at the 0.5 mark
  • Then diluting it with distilled cold water up to the 11 mark.
38
Q

Why should you discard the first unit in the pipet before charging the hemocytometer when counting sperm cells using cold water as the diluting fluid?

A
  • The first unit in the pipet is discarded before charging the hemocytometer
  • It contains purely diluting fluid (cold water)
39
Q

What is the formula for sperm cell counting using cold water as the diluting fluid?

A
  • DF = (11 - 1) / 0.5, which equals 20.
40
Q

What is the counting area for sperm cell counting using a hemocytometer?

A
  • Includes the RBC counting square, 4 corner small squares, and the center small square.
41
Q

How many elevated counting areas does a hemocytometer have?

A
  • A hemocytometer has 2 elevated counting areas.
42
Q

How many large squares are there in one entire counting area of a hemocytometer?

A
  • In one entire counting area of a hemocytometer, there are 9 large squares.
43
Q

In hematology, which specific component is the center large square intended for counting?

A
  • In hematology, the center large square is intended for PLATELET COUNT.
44
Q

How is the center large square further divided for counting purposes?

A
  • The center large square is divided into 25 small squares for counting purposes.
45
Q

How do you calculate the average red blood cell (RBC) count using the RBC counting square method, given an example with counts of 100 and 150 RBCs?

A
  • (100 + 150 = 250) and then divide by 2 (250 / 2 = 125).
46
Q

How do you calculate the total sperm concentration when you have 125 sperm in one unit of measurement?

A
  • Multiply the number of sperm (125) by 1,000,000
  • Which equals 125,000,000 sperm per milliliter (sperm/mL).
47

  • Multiply the total sperm concentration by the volume of semen.
49
Q

What is the significance of a “Normal Value Count” of >40,000,000 for “ejaculate”?

A
  • Typically refers to the normal range of sperm count in a semen sample
  • It indicates a high concentration of sperm, which is important for fertility.

A
  • Should be assessed using a well-mixed
  • Liquefied specimen within 1 hour of specimen collection.
52
Q

What happens if the sperm sample is not liquefied, clotted, or coagulated?

A
  • If the sample is not liquefied, clotted, or coagulated
  • The specimen will not exhibit movement.
53
Q

What is considered a normal value for sperm motility?

A
  • A normal value for sperm motility is 2.0 and above.
54
Q

What is the shape and size of the head of a sperm cell?

A
  • Oval-shaped and measures approximately 5 µm long and 3 µm wide.
55
Q

What is the function of the acrosomal cap in a sperm cell?

A
  • Contains enzymes critical for ovum penetration
  • Helping the sperm penetrate the ovum during fertilization.
56
Q

What is the function of the neckpiece in morphology?

A
  • Serves as a small structure that attaches the head to the tail and the midpiece.
57
Q

What is the function of the mitochondrial sheath in the context of morphology?

A
  • The mitochondrial sheath produces energy required by the tail for motility.
58
Q

How long is the midpiece in morphology, and what is its significance?

A
  • Approximately 7 µm long
  • It is the thickest part of the tail surrounded by the mitochondrial sheath.
59
Q

What is the approximate length of the tail in morphology?

A
  • The tail in morphology is approximately 4-5 µm long.
60
Q

How is mtDNA inherited?

A
  • MtDNA is inherited exclusively from one’s mother.
61
Q

What role does the acrosomal cup enzyme play during fertilization?

A
  • Is required for the sperm to penetrate the ovum during the fertilization process.
62
Q

What happens to the sperm’s components during the penetration process?

A
  • If the sperm’s head inserts into the ovum, only the nucleus enters
  • While the midpiece up to the tail of the sperm will detach or be removed.
