Which male reproductive structure produces prostatic fluid, which contributes 20-30 percent of the volume of semen?  It is a small, muscular, rounded organ about 4 cm in diameter.

• Scrotum

• Prostate gland

• Epididymis

• Testes

Which of the following is NOT a role of the epididymis?

• Monitors and adjusts the composition of the fluid produced by the seminiferous tubules.

• Acts as a recycling center for damaged spermatozoa.

• Transports urine from the urinary bladder to the penis.

• Stores and protects spermatozoa and facilitates their functional maturation.

Erection of the penis occurs when

• there is sympathetic activation of penile arteries

• arterial branches are constricted and muscular partitions are tense

• The vascular channels become engorged with blood

• a, b, and c are correct

Impotence is the inability to

• produce sufficient amounts of spermatozoa for fertilization

• achieve or maintain an erection

• achieve an orgasm

• ejaculate

Trace the duct system that the sperm traverses from the site of its production to the exterior of the body.

• epididymis → rete testis → efferent ducts → seminiferous tubules → ejaculatory duct→ ductus deferens → urethra

• seminiferous tubules → rete testis → efferent ducts → epididymis → ductus deferens → ejaculatory duct → urethra

• epididymis→ rete testis → efferent ducts → seminiferous tubules → ductus deferens → urethra→ ejaculatory duct

• prostate gland → rete testis → urethra → epididymis → ductus deferens → ejaculatory duct → seminiferous tubules

As long as a person has no symptoms of an STI, they:

• Cannot pass on an STI

• Don't have an STI

• A and B

• None of the above
