Question 1

What is the primary location where semen is produced in the male reproductive system?

Answer 1

• Semen is primarily produced in the testes.

Question 2

Which organs contribute to the four fractions that make up semen?

Answer 2

• The testes,
  *epididymis
  *seminal vesicles
  *prostate gland
  *bulbourethral gland

Question 3

What are the paired glands in the scrotum responsible for the production of spermatozoa and the secretion of sperm?

Answer 3

• Testes, which contain the Seminiferous Tubules.

Question 4

What is the primary function of the epididymis?

Answer 4

• The primary function of the epididymis is the storage of sperm.

Question 5

What is the primary function of the seminal vesicles in semen production?

Answer 5

• The seminal vesicles produce most of the fluid present in semen, serving as the transport medium for sperm.

Question 6

What is the significance of fructose in the seminal fluid produced by the seminal vesicles?

Answer 6

• Fructose in the seminal fluid is used by sperm for the energy needed for motility and movement.

Question 7

What is the role of flavin in the seminal fluid produced by the seminal vesicles?

Answer 7

• Flavin is responsible for the gray appearance of sperm.

Question 8

Approximately what percentage of the total semen volume is contributed by the fluid produced by the seminal vesicles?

Answer 8

• The fluid produced by the seminal vesicles accounts for 60 to 70 percent of the total semen volume.

Question 9

What is the role of the prostate gland during ejaculation?

Answer 9

• Aid in propelling sperm through the urethra by contracting during the ejaculation process.

Question 10

What percentage of acidic fluid is produced by the prostate gland?

Answer 10

• The prostate gland produces approximately 20-30% of the acidic fluid in semen.

Question 11

What are some components found in the milky acidic fluid produced by these glands?

Answer 11

• The milky acidic fluid contains Acid Phosphatase, Citric Acid, Zinc, and Proteolytic enzymes.

Question 12

• These components are responsible for both coagulation and liquefaction of semen following ejaculation.

Answer 12

Acid Phosphatase
§ Citric Acid
§ Zinc
§ Proteolytic enzymes

Question 13

What is the primary function of the bulbourethral gland?

Answer 13

• It contributes about 5% of the fluid volume in the form of thick alkaline mucus
• That helps to neutralize the vaginal acidity present as a result of normal bacterial vaginal flora.

Question 14

What role does Lactobacillus acidophilus play in the female vagina?

Answer 14

• Lactobacillus acidophilus produces an acidic environment in the female vagina.

Question 15

Which enzymes in the Acrosome are responsible for ovum penetration?

Answer 15
