What is the purpose of spermiogenesis?
- A. The stem cell line is built through the process of spermiogenesis.
- B. Spermiogenesis produces type A cells from each spermatogonium.
- C. Spermatids are streamlined to form sperm via spermiogenesis.
- D. Spermiogenesis results in the production of two sperm from one primary spermatocyt
Correct Answer: C
Rationale: The correct answer is C: Spermatids are streamlined to form sperm via spermiogenesis. Spermiogenesis is the final stage of spermatogenesis where round spermatids mature into spermatozoa. During spermiogenesis, the spermatids undergo significant structural changes, including the formation of the acrosome, tail, and mitochondria, to become fully functional sperm cells. Choices A and B are incorrect because spermiogenesis does not involve building the stem cell line or producing type A cells. Choice D is incorrect because spermiogenesis does not result in the production of two sperm from one primary spermatocyte; rather, it is the process by which spermatids are transformed into mature sperm cells.

About the external male genital organ, we can state the following:
- A. it is part of the urinary ducts, being a urination organ;
- B. it is represented by the urethra;
- C. it is a pair organ;
- D. it is located above the scrotum, anterior to the pubian symphisis;
Correct Answer: B
Rationale: Step-by-step rationale for why answer B is correct:
1. The external male genital organ is represented by the urethra, which is the duct that carries urine from the bladder out of the body.
2. The urethra is responsible for both urination and ejaculation.
3. The other choices are incorrect because the external male genital organ is not part of the urinary ducts, not a pair organ, and not located above the scrotum.
Why should a nurse educate women to have regular gynecologic examinations and Pap tests?
- A. It helps decide the mode of surgical treatment.
- B. It is the best cure for most infections.
- C. It increases the potential for an early diagnosis.
- D. It is an inexpensive test.
Correct Answer: C

Correct Answer: B
Rationale: Reassuring the patient that tightness is normal post-surgery helps alleviate anxiety.
Which of the following is a fungal disease of the reproductive system?
- A. Syphilis
- B. Gonorrhea
- C. Candidiasis
- D. Genital Herpes
Correct Answer: C
Rationale: The correct answer is C: Candidiasis. Candidiasis is a fungal infection caused by the Candida fungus, commonly affecting the reproductive system. It can cause symptoms like itching, burning, and abnormal discharge.
A: Syphilis is a bacterial infection transmitted through sexual contact.
B: Gonorrhea is a bacterial infection affecting the reproductive system.
D: Genital Herpes is a viral infection that affects the genital area.
In summary, Candidiasis is the only fungal disease listed, making it the correct choice for a fungal infection of the reproductive system.
The convoluted seminiferous tubules:
- A. are located in the lobules of the male gonad;
- B. continue with the deferent duct;
- C. there are three tubules for each testicular lobule;
- D. continue with the straight tubules;
Correct Answer: A
Rationale: The correct answer is A because the convoluted seminiferous tubules are indeed located in the lobules of the male gonad, which is the testis. These tubules are where spermatogenesis occurs, the process of sperm production. Option B is incorrect as the convoluted tubules do not continue with the deferent duct, but they connect to the straight tubules. Option C is incorrect because there are numerous convoluted seminiferous tubules within each testicular lobule, not just three. Option D is incorrect as the convoluted tubules do not continue with the straight tubules directly; they lead to the rete testis before connecting to the straight tubules.
