Identify the statements that correctly describe the maturation and storage of sperm:
A. Sperm become motile immediately after formation in the seminiferous tubules.
B. Sperm acquire motility after residing in the epididymis for 18 to 24 hours, even though inhibitors in the epididymal fluid prevent final motility until after ejaculation.
C. The primary storage location for sperm is the vas deferens, where they can remain fertile for over a month.
D. Growth hormone deficiency, as seen in pituitary dwarfs, can lead to a significant reduction or absence of spermatogenesis.
