When does the testes begin to develop during pregnancy?
- A.
4th or 5th week
- B.
7th or 8th week
- C.
10th or 12th week
- D.
16th or 18th week
Correct Answer
B. 7th or 8th weekExplanation
During pregnancy, the testes begin to develop in the 7th or 8th week. This is when the fetus undergoes sexual differentiation and the gonads start to develop into either testes or ovaries. The testes develop from a structure called the genital ridge, which forms during this time. It is during this period that the testes start to produce testosterone, a hormone that is essential for the development of male reproductive organs. Therefore, the correct answer is 7th or 8th week.Rate this question:

What hormone does the testes secrete that aids in maturing sperm and development of male secondary sex characteristics?
- A.
Progesterone
- B.
Testosterone
- C.
Follicle-stimulating hormone
- D.
Lutienizing hormone
Correct Answer
B. TestosteroneExplanation
Testosterone is the correct answer because it is the hormone secreted by the testes that plays a crucial role in maturing sperm and the development of male secondary sex characteristics. It is responsible for the growth of facial and body hair, deepening of the voice, and muscle development. Testosterone also plays a role in regulating libido and maintaining bone density. Progesterone, follicle-stimulating hormone, and luteinizing hormone are not secreted by the testes and do not have the same effects on sperm maturation and male secondary sex characteristics.Rate this question:

Which of the following store mature sperm for about 18 hours?
- A.
Seminal vesicle
- B.
Vas deferens
- C.
Tubules
- D.
Epididymis
Correct Answer
D. EpididymisExplanation
The epididymis is a coiled tube located on the back of each testicle that serves as a storage and maturation site for sperm. It allows the sperm to gain the ability to swim and fertilize an egg. The sperm can remain in the epididymis for up to 18 hours before being ejaculated during sexual activity.Rate this question:

The _____________________ is a passageway for sperm and joins the ejaculatory duct.
- A.
Seminal vesicle
- B.
Vas deferens
- C.
Tubules
- D.
Epididymis
Correct Answer
B. Vas deferensExplanation
The vas deferens is a tube that serves as a passageway for sperm and connects the epididymis to the ejaculatory duct. It transports mature sperm from the epididymis to the urethra during ejaculation. The seminal vesicle, on the other hand, is responsible for producing and storing seminal fluid, while the epididymis is where sperm mature and are stored. Tubules, in this context, is a general term that does not specifically refer to the passageway for sperm.Rate this question:

Sperm are produced in the _____________________.
- A.
Seminal vesicle
- B.
Vas deferens
- C.
Ovaries
- D.
Epididymis
Correct Answer
A. Seminal vesicleExplanation
Sperm are actually produced in the testes, not in the seminal vesicle. The seminal vesicle is responsible for producing and storing a fluid that mixes with sperm to form semen. The vas deferens is a tube that transports sperm from the testes to the urethra. The ovaries are part of the female reproductive system and are responsible for producing eggs. The epididymis is a structure located on top of the testes where sperm mature and are stored before ejaculation.Rate this question:

Glucose, which is secreted by the glands in the seminal vesicles provides nourishment for the sperm.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because glucose is not secreted by the glands in the seminal vesicles. The seminal vesicles actually secrete fructose, which provides nourishment for the sperm. Glucose is not involved in this process.Rate this question:

The urethra is surrounded by what type of tissue?
- A.
Epithelial tissue
- B.
Subcutaneous tissue
- C.
Spongelike erectile tissue
- D.
Voluntary muscular tissue
Correct Answer
B. Subcutaneous tissueExplanation
The urethra is surrounded by subcutaneous tissue. Subcutaneous tissue is the layer of tissue located just beneath the skin. It is composed of fat cells and connective tissue, providing insulation, cushioning, and support to the underlying structures. In the case of the urethra, the subcutaneous tissue helps protect and support the urethra, which is the tube that carries urine from the bladder to the external opening.Rate this question:

The following are examples of male secondary sex characteristics except:
- A.
Sexual desire
- B.
Body hair growth
- C.
Muscle and tissue building
- D.
Improved critical thinking
Correct Answer
D. Improved critical thinkingExplanation
The given options are all examples of male secondary sex characteristics, except for improved critical thinking. Sexual desire, body hair growth, and muscle and tissue building are all physical changes that are associated with male puberty. However, improved critical thinking is not directly linked to male secondary sex characteristics. While cognitive development may occur during puberty, it is not specific to males and does not fall under the category of physical changes.Rate this question:

Which of the following choices is the correct order of the pathway of sperm from production to expulsion?
- A.
1st-tubule, 2nd-epididymis, 3rd-vas deferens, 4th-ejaculatory duct, 5th-urethra.
- B.
1st-tubule, 2nd-epididymis, 3rd-ejaculatory duct, 4th-vas deferens, 5th-urethra
- C.
1st-epididymis, 2nd-tubule, 3rd-vas deferens, 4th-ejaculatory duct, 5th-urethra
- D.
1st- epididymis, 2nd-ejaculatory duct, 3rd-tubule, 4th-vas deferens, 5th-urethra
Correct Answer
A. 1st-tubule, 2nd-epididymis, 3rd-vas deferens, 4th-ejaculatory duct, 5th-urethra.Explanation
The correct order of the pathway of sperm from production to expulsion is as follows: 1st-tubule, 2nd-epididymis, 3rd-vas deferens, 4th-ejaculatory duct, 5th-urethra. Sperm is produced in the seminiferous tubules of the testes. From there, it moves into the epididymis, where it matures and becomes motile. Next, it travels through the vas deferens, a muscular tube that carries sperm from the epididymis to the ejaculatory duct. The ejaculatory duct then connects to the urethra, which allows the sperm to be expelled from the body during ejaculation.Rate this question:

Regarding the components of semen, what is the percentage of fluid secreted by the prostate gland?
- A.
5
- B.
20
- C.
30
- D.
60
Correct Answer
D. 60Explanation
The prostate gland secretes about 30-35% of the fluid in semen. However, the correct answer given is 60%, which is incorrect. The fluid secreted by the prostate gland contains enzymes, citric acid, and zinc, which help nourish and protect the sperm. It also helps in the liquefaction of semen after ejaculation.Rate this question:

Regarding the components of the semen, what is the percentage of fluid secreted from the testes and epididymis?
- A.
5
- B.
20
- C.
30
- D.
60
Correct Answer
A. 5Explanation
The correct answer is 5. The question is asking about the percentage of fluid secreted from the testes and epididymis in semen. The testes and epididymis produce only a small amount of fluid compared to other components of semen, such as sperm cells, prostatic fluid, and seminal vesicle fluid. Therefore, the percentage of fluid secreted from the testes and epididymis is relatively low, which is represented by the answer 5.Rate this question:

Ejaculate may contain between 40 million to 600 million sperms.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because ejaculate, which refers to semen released during ejaculation, can indeed contain between 40 million to 600 million sperms. Sperm is the male reproductive cell and is responsible for fertilizing the female egg during sexual reproduction. The large number of sperms in ejaculate increases the chances of successful fertilization and pregnancy.Rate this question:

Inflammation of prostate is known as:
- A.
Epididymitis
- B.
Prostatitis
- C.
Proatitis
- D.
Epidymitis
Correct Answer
B. ProstatitisExplanation
Prostatitis is the correct answer because it refers to the inflammation of the prostate gland. The other options, epididymitis and epidymitis, are incorrect as they refer to the inflammation of the epididymis, which is a different structure in the male reproductive system. The option "proatitis" is not a recognized medical term and does not correspond to any known condition. Therefore, prostatitis is the most appropriate term to describe the inflammation of the prostate.Rate this question:

Which disease is most common in newborns that cause excess fluid within the structures around the testes and an enlargement of the scrotum?
- A.
Hydrocele
- B.
Epididymitis
- C.
Hypertrophy
- D.
None of the above
Correct Answer
A. HydroceleExplanation
Hydrocele is the correct answer because it is a condition that commonly affects newborns and causes excess fluid to accumulate around the testes, leading to an enlargement of the scrotum. Epididymitis is the inflammation of the epididymis, which is not specifically associated with excess fluid or scrotum enlargement. Hypertrophy refers to the abnormal increase in the size of an organ or tissue, which is not directly related to the symptoms described. Therefore, none of the other options are the most common disease in newborns causing these specific symptoms.Rate this question:

Benign hypertrophy can result in constriction of the urethra.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Benign hypertrophy refers to the non-cancerous enlargement of an organ or tissue. In the case of the urethra, benign hypertrophy can lead to its constriction or narrowing. This can cause difficulty in urination, as the urine flow is obstructed due to the reduced diameter of the urethra. Therefore, the statement "Benign hypertrophy can result in constriction of the urethra" is true.Rate this question:

Prostate cancer is more common in African Americans.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Prostate cancer is indeed more common in African Americans. Studies have shown that African American men have a higher incidence rate of prostate cancer compared to men of other races. They are also more likely to be diagnosed with prostate cancer at a younger age and have a more aggressive form of the disease. The exact reasons for these disparities are not fully understood, but factors such as genetics, access to healthcare, and socioeconomic factors may play a role.Rate this question:

Prostate cancer is diagnosed by urethra examination and prostate-specific antigen (PSA) blood tests.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because prostate cancer is not diagnosed by urethra examination. Instead, it is typically diagnosed through a combination of digital rectal examination (DRE), where a doctor feels the prostate gland for abnormalities, and a PSA blood test, which measures the levels of a protein called prostate-specific antigen in the blood. These methods, along with other diagnostic tests such as a biopsy, help doctors determine if a person has prostate cancer.Rate this question:

- D.
Every year after male turns 60 years old
Correct Answer
C. Every year after male turns 50 years oldExplanation
Prostate examinations are typically recommended for men starting at the age of 50. This is because the risk of developing prostate cancer increases with age, and regular screenings can help detect any potential issues early on. However, it is important to note that the frequency and timing of prostate examinations may vary based on an individual's medical history and risk factors. It is always best to consult with a healthcare professional for personalized advice.Rate this question:
