B. they undergo further spermiogenesis and development.

C. they are nonmotile and incapable of fertilizing an oocyte.

D. additional fluid is added to increase their motility.

E. stereocilia motility increases sperm motility.

5. Where do the sperm become activated and able to fertilize an oocyte?

A. In the testis

B. In the epididymis

C. In the efferent ducts

D. In the female reproductive tract

E. In the seminiferous tubules

ANSWERS

1. Correct Answer: D. Sertoli cells. Their tight junctions separate the
seminiferous tubules into adluminal and basal compartments to protect the
developing sperm from an autoimmune response.

2. Correct Answer: B. It prevents an autoimmune response to sperm and

induction of infertility.

3. Correct Answer: A. Testosterone. This hormone is essential for
spermatogenesis, maintenance of accessory reproductive organs, and
secondary sex characteristics in males.

4. Correct Answer: C. They are nonmotile and incapable of fertilizing an
oocyte. Further maturation is necessary in the epididymis before full

maturity and fertilizing ability.

5. Correct Answer: D. In the female reproductive tract. Here, they are
activated by a process of capacitation, at which time the decapacitation
factor is removed and the sperm can fertilize the ovulated oocyte.
