	 seminal gland (seminal vesicle).
	 corpus cavernosum.
	 bulbourethral gland.
	 prostate gland.
	 preputial gland.

	 seminal vesicles.
	 prostate glands.
	 preputial glands.
	 bulbo-urethral glands.
	 Bartholin glands.

bulbo-urethral glands.

Semen contains all of the following, except ``` seminal fluid. spermatogonia. prostaglandins. fibrinogen. spermatozoa. ```

spermatogonia.

The fold of skin that covers the glans penis is the ``` corpus spongiosum. prepuce. penile urethra. corpus cavernosum. ejaculatory duct. ```

prepuce.

The erectile tissue that surrounds the urethra is the ``` corpus spongiosum. penile urethra. corpus cavernosum. membranous urethra. glans penis. ```

corpus spongiosum.

The role of FSH in males is to stimulate the interstitial cells to produce testosterone. develop and maintain secondary sex characteristics. influence sexual behaviors and sex drive. initiate sperm production in the testes. stimulate the nurse cells to produce inhibin.

initiate sperm production in the testes.

The special type of cell division required to produce gametes is called ``` maturation. capacitation. fertilization. meiosis. mitosis. ```

meiosis.

Spermatozoa are functionally matured within the ``` epididymis. rete testes. ductus deferens. seminiferous tubules. seminal gland (seminal vesicle). ```
