Concept:Although generated in the tubules, structurally mature sperm (spermatozoa) are primarily stored in a specialized duct system.
Solution:- Spermatogenesis produces spermatids, which undergo spermiogenesis inside the seminiferous tubules.
- However, these cells are swept out of the testis almost immediately once fully formed.
- They arrive in the epididymis (a structure tightly coiled against the testis), where the vast majority of mature spermatozoa are actually stored, concentrated, and acquire motility until ejaculation.
Why other options are incorrect:Seminiferous tubules primarily contain
developing stages (spermatocytes, spermatids). Interstitial cells are outside the tubules. Sertoli cells nurse the sperm but don't store the final spermatozoa payload.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
