Where does spermatogenesis occur?
-
Epididymis
-
Efferent ducts
-
Spermatic cords
-
Seminiferous tubules
Correct Answer
A. Seminiferous tubulesExplanation
Spermatogenesis, the process of sperm production, occurs in the seminiferous tubules. These tubules are located within the testes and are responsible for the production and maturation of sperm cells. The seminiferous tubules contain specialized cells called germ cells, which undergo a series of divisions and differentiations to eventually produce mature sperm. The other options mentioned, such as the epididymis, efferent ducts, and spermatic cords, are not directly involved in spermatogenesis but play important roles in the transport and storage of sperm after they are produced in the seminiferous tubules.Rate this question:

Which sonographic technique is used to document varicocele?
-
Expiration
-
Inspiration
-
Valsalva maneuver
-
Quiet respiration
Correct Answer
A. Valsalva maneuverExplanation
The Valsalva maneuver is a sonographic technique used to document varicocele. During this maneuver, the patient is asked to bear down as if having a bowel movement, which increases intra-abdominal pressure. This helps to detect and assess the presence of varicoceles by causing them to dilate and become more visible on the ultrasound image. The other options, expiration, inspiration, and quiet respiration, do not involve the necessary increase in intra-abdominal pressure to effectively visualize varicoceles.Rate this question:

What changes can occur in approximately 40% of the postvascectomy patients?
-
Atrophy of the scrotal sac
-
Enlargement of the epididymis
-
Infarction of one or both testis
-
Hyperemia of one or both testis
Correct Answer
A. Enlargement of the epididymisExplanation
Approximately 40% of postvasectomy patients can experience enlargement of the epididymis. This is because the vasectomy procedure involves cutting and sealing the vas deferens, which can lead to congestion and swelling in the epididymis. This enlargement is usually temporary and resolves on its own over time. Atrophy of the scrotal sac, infarction of one or both testis, and hyperemia of one or both testis are not common changes that occur in postvasectomy patients.Rate this question:
