1.
Which is the chief male sex organ?
Correct Answer
A. Penis
Explanation
The penis is considered the chief male sex organ because it plays a crucial role in sexual reproduction. It is responsible for delivering sperm into the female reproductive tract during sexual intercourse. The penis also contains erectile tissue that allows it to become erect, enabling sexual penetration and pleasure. Additionally, the penis is involved in the process of urination, as it acts as a conduit for the expulsion of urine from the body.
2.
Which of these produces semen?
Correct Answer
C. Testicles
Explanation
The testicles are responsible for producing semen. They are a pair of male reproductive organs located in the scrotum. The testicles produce sperm cells, which are combined with fluids from the prostate gland and seminal vesicles to form semen.
3.
What fertilizes the ovum of the female?
Correct Answer
A. Sperm
Explanation
Sperm is the correct answer because it is the male reproductive cell that fertilizes the ovum, or egg, of the female. The sperm is released from the penis during sexual intercourse and travels through the female reproductive system to reach the ovum. Once the sperm penetrates the ovum, fertilization occurs, resulting in the formation of a zygote, which eventually develops into an embryo. The semen and scrotum are not directly involved in fertilizing the ovum.
4.
What does the fertilized ovum develop into?
Correct Answer
B. Zygote
Explanation
The fertilized ovum develops into a zygote. After fertilization, the sperm and egg combine to form a zygote, which is the earliest stage of development for a new organism. The zygote then undergoes cell division and differentiation to develop into an embryo, which eventually grows into a fetus and then a baby. The other options listed, such as sac, egg, and baby, are not accurate descriptions of the developmental stages after fertilization.
5.
Which of these is involved in the transportation of sperm?
Correct Answer
B. Vas deferens
Explanation
The vas deferens is involved in the transportation of sperm. It is a long, muscular tube that connects the epididymis to the ejaculatory duct. During ejaculation, the vas deferens contracts and pushes the sperm from the epididymis towards the urethra, where it is then expelled from the body. The other options listed (sectoral sac, prostate, and scrotum) are not directly involved in the transportation of sperm.
6.
What is an abnormally tight skin that is difficult to retract?
Correct Answer
B. ParapHimosis
Explanation
Paraphimosis is the correct answer because it refers to a condition where the foreskin of the penis becomes trapped behind the glans and cannot be easily retracted. This causes the skin to become tight and difficult to retract, leading to potential complications if not treated promptly. Mosiad, Phimosis, and Grandulosis are not relevant to the given question.
7.
What is a condition in which the urethral meatus fails to reach the end of the penis?
Correct Answer
C. Hypospadiasis
Explanation
Hypospadiasis is a condition in which the urethral meatus, the opening of the urethra, is not located at the tip of the penis but rather on the underside. This is a congenital abnormality that occurs during fetal development. It can vary in severity, with the meatus being located anywhere along the underside of the penis, from near the tip to the scrotum. Hypospadiasis can cause difficulties with urination and may require surgical correction.
8.
What is a persistent, painful erection?
Correct Answer
A. Priapism
Explanation
Priapism is a medical condition characterized by a persistent and painful erection that lasts for an abnormally long time. It is not related to sexual arousal or stimulation and can occur without any sexual activity. Priapism is usually caused by problems with blood flow in the penis, such as blood clots or certain medications. If left untreated, it can lead to tissue damage and permanent erectile dysfunction. Therefore, priapism is the correct answer to the question.
9.
What is the inflammation of the glans penis?
Correct Answer
D. Balanitis
Explanation
Balanitis is the inflammation of the glans penis, which is the rounded head of the penis. This condition is commonly caused by poor hygiene, irritation from certain substances, or infections. Symptoms of balanitis may include redness, swelling, itching, and discomfort in the affected area. It is important to seek medical attention if experiencing these symptoms to receive proper diagnosis and treatment.
10.
What is the failure of the testis to descend into the scrotum?
Correct Answer
A. Cryptorchidism
Explanation
Cryptorchidism refers to the failure of the testis to descend into the scrotum. This condition occurs when one or both testes remain in the abdominal cavity or fail to fully descend into the scrotum. It is a common congenital abnormality in newborn males and can lead to infertility and an increased risk of testicular cancer if left untreated. Treatment options include hormonal therapy and surgical intervention to bring the testes into the scrotum.
