What is the process by which male spermatogonia develop into mature spermatoza, also known as a sperm cell?
Correct Answer
C. Spermatogenesis
Explanation
Spermatogenesis is the process by which male spermatogonia develop into mature spermatozoa, also known as sperm cells. This process takes place in the testes and involves several stages, including mitosis, meiosis, and spermiogenesis. Mitosis allows spermatogonia to multiply, while meiosis reduces the chromosome number and creates haploid cells called spermatids. Finally, spermiogenesis involves the transformation of spermatids into spermatozoa with a head, midpiece, and tail. This complex process is essential for the production of functional sperm cells necessary for sexual reproduction.
2.
Which of the following is not a male reproductive system disorder?
Correct Answer
B. Hypofibrinogenemia
Explanation
Hypofibrinogenemia is a disorder related to the blood clotting process, specifically a deficiency in fibrinogen, a protein necessary for blood clot formation. It is not directly related to the male reproductive system. Testicular cancer, epididymitis, and hypogonadism are all disorders that affect the male reproductive system.
3.
What is the most predominant of the male hormones?
Correct Answer
D. Testosterone
Explanation
Testosterone is the most predominant male hormone. It is primarily produced in the testicles and is responsible for the development of male reproductive tissues and secondary sexual characteristics. It plays a crucial role in the growth and maintenance of muscle mass, bone density, and sperm production. Testosterone also influences mood, energy levels, and libido in males.
4.
They are located in a sac at the base of the penis called the scrotum.
Correct Answer
A. Testicles
Explanation
The testicles are located in a sac called the scrotum, which is situated at the base of the penis. This location allows for the testicles to be outside of the body, which is important for maintaining the optimal temperature for sperm production. The scrotum helps to regulate the temperature of the testicles, keeping them slightly cooler than the rest of the body. This is necessary for the production of healthy sperm. Therefore, the testicles are correctly identified as being located in the scrotum.
5.
What secretes a thick fluid that mixes with seminal fluid produced by the prostate and sperm from the testes to form semen?
Correct Answer
B. Seminal vesicles
Explanation
The seminal vesicles secrete a thick fluid that mixes with the seminal fluid produced by the prostate and the sperm from the testes to form semen. This fluid contains various substances, including fructose, prostaglandins, and enzymes, which provide nourishment and support for the sperm. The secretion from the seminal vesicles contributes to the overall composition and function of semen during ejaculation.

Why is the scrotum located on the outside of the male body?
7.
What produces prostate specific antigen and prostatic acid phosphates that are present in seminal fluid?
Correct Answer
C. Prostate gland
Explanation
The prostate gland produces prostate specific antigen and prostatic acid phosphates that are present in seminal fluid. These substances are important for the liquefaction of semen and the proper functioning of sperm. The seminal vesicles contribute to the production of semen, but they do not produce these specific substances. Spermatoza are the actual sperm cells, and the vas deferens is a tube that transports sperm, but neither of them produce prostate specific antigen or prostatic acid phosphates.
8.
The internal structe is made up of 2 cylinder-shaped vascuar tissue bodies
Correct Answer
B. Penis
Explanation
The internal structure of the penis is composed of two cylinder-shaped vascular tissue bodies. These bodies, known as the corpora cavernosa, run along the length of the penis and are responsible for its erectile function. When stimulated, these tissues fill with blood, causing the penis to become erect. The presence of these vascular structures allows for increased blood flow and engorgement, leading to a firm and erect penis during sexual arousal.
