Question 1

It is believed that the purpose of the secretions of the Cowper's glands is to

Accepted Answer

The Cowper's glands secrete a fluid that helps buffer the acidic environment within the urethra, which helps protect the sperm as they travel through the urethra during ejaculation. This function helps increase the chance of fertilization. The other choices are not accurate as the Cowper's glands do not play a role in maintaining the erection of the penis or optimal testosterone levels, nor do they specifically help with masturbation.

Question 2

Testosterone

Accepted Answer

Testosterone regulates sex drive.

Question 3

Jaden is bullied in school because of a physiological condition that has caused the abnormal growth of his breasts. Which of the following is most likely the reason that has triggered this condition in Jaden?

Accepted Answer

Abnormal growth of breasts in males is called gynecomastia and is often caused by an imbalance of hormones. In this case, Jaden's higher levels of estrogen than testosterone are likely the cause of his condition.

Question 4

Oral stimulation of the anus is referred to as

Accepted Answer

Oral stimulation of the anus is commonly known as rimming.

Question 5

Immature sperm are stored in

Accepted Answer

Immature sperm are stored in the epididymis, where they continue to mature and gain the ability to swim. The vas deferens is a tube that carries mature sperm from the epididymis to the urethra for ejaculation. Leydig cells are responsible for producing testosterone, which is necessary for sperm production. Spermatids are the final stage of sperm development, after which they mature into fully functional sperm.

Question 6

The ________ are structures that encircles the urethra just below the urinary bladder and produces about 30% of the seminal fluid that nourishes and transports sperm.

Accepted Answer

The prostate gland is a part of the male reproductive system, present just below the bladder and encircling the urethra. It produces about 30% of the seminal fluid which is responsible for nourishing and transporting sperm. The seminal vesicles also produce seminal fluid, but they are not present around the urethra. The epididymis is a structure connected to the testes responsible for storing and maturing sperm. The frenulum is a band of tissue present on the underside of the penis.

Question 7

Spermatogenesis takes place within the

Accepted Answer

Spermatogenesis, the process of sperm cell production, occurs within the seminiferous tubules of the testes.

Question 8

Which of the following muscles within the scrotal sac causes the testes to elevate?

Accepted Answer

The cremaster muscle is responsible for the elevation and contraction of the testes in response to temperature changes and physical activity. The other listed muscles are not related to the scrotal sac or testes.

Question 9

A steroid hormone synthesized from cholesterol that triggers the production of sperm is

Accepted Answer

Testosterone is a steroid hormone synthesized from cholesterol that is responsible for triggering the production of sperm in males. Estrogen (choice A) is a female hormone, while human chorionic gonadotropin (hCG) (choice C) and gonadotropin-releasing hormone (GnRH) (choice D) play roles in reproductive processes but do not directly trigger the production of sperm.

Question 10

Gynecomastia refers to the

Accepted Answer

Gynecomastia refers to the swelling or enlargement of the male breast. It is caused by an imbalance of hormones, specifically an increase in estrogen relative to testosterone. It can occur in newborns, adolescents going through puberty, and older men due to age-related hormonal changes.

Question 11

In about 3-4% of full-term male infants and more commonly in premature male infants, one or both of the testes fail to descend. This condition is known as

Accepted Answer

Cryptorchidism is the medical term for undescended testicles, which occurs in about 3-4% of full-term male infants and more commonly in premature male infants.

Question 12

The scrotum is

Accepted Answer

The scrotum is a pouch of loose skin that holds the testes.

Question 13

Within the connective tissues of a man's testes are Leydig cells, which

Accepted Answer

Leydig cells are responsible for secreting androgens, such as testosterone, which are important in the development of male reproductive structures and characteristics. They do not store sperm or produce sperm, and are not responsible for the production of smegma.

Question 14

Amahle, a 20-year-old, gives birth to a premature male child. After the initial examination of the child, the physician informs her that one of the child's testes has failed to descend into the scrotum. In this scenario, the child's condition can be referred to as

Accepted Answer

Cryptorchidism refers to the failure of one or both testes to descend into the scrotum. Nyctalopia refers to poor vision in low light conditions. Dysarthria refers to difficulty in articulating speech. Opisthotonos refers to a severe muscle spasm resulting in arching of the back and neck.

Question 15

Ken and Marie have two children and choose to have no more. The surgery for Ken that prevents transportation of sperm from the testes to the urethra by clipping is called a(n) ________.

Accepted Answer

A vasectomy is a surgical procedure that involves cutting or clipping the vas deferens, which carries sperm from the testes to the urethra, thus preventing the transportation of sperm during ejaculation. A mastectomy is a surgical procedure that removes breast tissue, a hysterectomy is a surgical procedure that removes the uterus, and an orchiectomy is a surgical procedure that removes the testes. These surgeries are not applicable to Ken's situation.

Question 16

Leydig cells are also known as

Accepted Answer

Leydig cells are also known as interstitial cells.

Question 17

Testosterone is made by men primarily in the

Accepted Answer

Testosterone is primarily made in the testes of men.

Question 18

In the context of male sex structures, the bulbourethral glands are also known as

Accepted Answer

The bulbourethral glands, which are part of the male reproductive system, are also known as Cowper's glands.

Question 19

Che, an adolescent, notices that his breasts have started swelling abnormally. He visits a physician who advices him to undergo a hormone test. The result shows that the amount of testosterone in Filip's body is less than the amount of estrogen. The medical condition is most likely called ________.

Accepted Answer

Gynecomastia is a medical condition characterized by the swelling of breast tissue in males, typically caused by an imbalance of hormones, where the amount of estrogen in the body is higher than that of testosterone. "Blue balls", "cryptorchidism", and "wet dreams" are not related to this medical condition.

Question 20

The thick, clear mucus that may appear at the tip of the erect penis before ejaculation is produced by

Accepted Answer

The thick, clear mucus that appears at the tip of the erect penis before ejaculation is produced by the Cowper's glands. These pea-sized glands located beneath the prostate gland secrete a clear, slippery fluid that serves to lubricate the urethra and neutralize any acidity from urine that may remain in the urethra.
