A male nurse is teaching a client about the scrotum and the ability of sperm to be effective in fertility. The nurse teaches the client that the sperm is contained in the testes and that its temperature is regulated by which of the following?
- A. Penis and surrounding structures
- B. Bladder tone
- C. Structure of the scrotum
- D. Smooth and skeletal muscles in the scrotum
Correct Answer: D
Rationale: The scrotum contains smooth and skeletal muscles that help regulate the temperature necessary for spermatogenesis.
Which hormone is made by the interstitial cells of the testis?
- A. Estrogen
- B. Testosterone
- C. Human chorionic gonadotropin (hCG)
- D. Luteinizing hormone (LH)
Correct Answer: B
Rationale: Certainly. The correct answer is B: Testosterone. Interstitial cells of the testis, also known as Leydig cells, synthesize and secrete testosterone. Testosterone is the primary male sex hormone responsible for the development of male reproductive tissues and characteristics. Estrogen (A) is primarily produced in the ovaries in females. Human chorionic gonadotropin (hCG) (C) is produced by the placenta during pregnancy. Luteinizing hormone (LH) (D) is secreted by the anterior pituitary gland and stimulates the interstitial cells to produce testosterone.
Before intercourse, a woman irrigates her vagina with a solution that lowers the pH of the vaginal fluid to 4.5. What will be the effect on sperm cells in the vagina?
- A. Metabolic rate will increase
- B. Rate of movement will decrease
- C. Formation of prostaglandin E2 will increase
- D. Rate of oxygen consumption will increase
Correct Answer: B
Rationale: The correct answer is B: Rate of movement will decrease. Sperm cells require a slightly alkaline environment to maintain their motility. Lowering the pH to 4.5 will create an acidic environment, causing decreased sperm motility. Choice A is incorrect as lowering pH doesn't affect metabolic rate. Choice C is incorrect because prostaglandin E2 formation is not directly related to pH changes. Choice D is incorrect as oxygen consumption rate of sperm cells is not affected by vaginal pH.
Which of the following is not a role of semen?
- A. Semen dilutes sperm.
- B. The acidity of semen helps neutralize the pH environment of a female's vagina
- C. Semen contains enzymes that enhance sperm motility.
- D. Semen contains antibiotic chemicals that destroy bacteria
Correct Answer: C
Rationale: The correct answer is C because semen does not contain enzymes that enhance sperm motility. Sperm motility is primarily influenced by the structure and health of the sperm themselves. Semen aids in sperm transport, provides nutrients, buffers the acidic vaginal environment, and contains antibiotics. Enzymes in semen primarily help with liquefaction of semen after ejaculation, not sperm motility. Choices A, B, and D are incorrect because semen does dilute sperm, neutralizes the acidic vaginal environment, and contains antibiotic chemicals, respectively.
Which one of the following is NOT one
- A. spermatid of the secondary sex characteristics
- B. primary spermatocyte typical of males?
- C. secondary spermatocyte
- D. deepening voice
Correct Answer: A
Rationale: The correct answer is A because a spermatid is a mature male germ cell that arises from the process of spermatogenesis, not a secondary sex characteristic.
- B is incorrect as a primary spermatocyte is indeed typical of males in the process of spermatogenesis.
- C is incorrect as a secondary spermatocyte is an intermediate stage in spermatogenesis.
- D is incorrect as deepening voice is a secondary sex characteristic associated with male puberty.
