The corpora cavernosa and corpus spongiosum are erectile
tissue. There are two corpora cavernosa and one corpus
spongiosum.

Steroid
hormones are cholesterol derivatives. Steroid hormones include
testosterone and estradiol.

The spherical structures seen in some prostatic alveoli are
called prostatic concretions.

Stereocilia are very long microvilli. Stereocilia are seen in the
epididymis and the hair cells of the ear.

Leydig cells produce testosterone. These are also called
"interstitial cells" or "interstitial cells of Leydig". Sertoli cells are
directly involved in spermatogenesis. They are also called
"sustentacular cells" or "nurse cells".

Sertoli cells produce inhibin and androgen-binding protein. The
interstitial cells of Leydig produce testosterone

The glandular epithelium of the prostate is most often simple
columnar, however a variety of types can be found.

The corpus spongiosum is also called the corpus cavernosum
urethrae. The corpora cavernosa and corpus spongiosum are
erectile tissue. The corpus cavernosum clitoridis is in the
female. The urethra is a muscular tube that runs from the
bladder. It transports both urine and semen.

Pseudostratified epithelium lines the epididymis.

Leydig cells produce testosterone. These are also called
"interstitial cells" or "interstitial cells of Leydig". Sertoli cells are
directly involved in spermatogenesis. They are also called
"sustentacular cells" or "nurse cells

The earliest cells of spermatogenesis are spermatogonia; these
are primitive cells. The primary spermatocyte is derived from
spermatogonia. This then develops into secondary
spermatocytes . The secondary spermatocyte is haploid. These
develop into spermatids. The mature sperm cell is spermatozoa.

Pseudostratified epithelium lines the vas deferens.

Sertoli cells produce inhibin and androgen-binding protein. The
interstitial cells of Leydig produce testosterone.

Pseudostratified epithelium lines the seminal vesicles.

The corpora cavernosa and corpus spongiosum are erectile

spongiosum.

The male genital duct system contains: rete testes, tubuli recti,
ductuli efferentes, ductus epididymidis, and ductus deferens.
The male accessory glands contain the bulbourethral glands,
seminal vesicles, and prostate.

The average testis in an adult man has between 400 and 600
seminiferous tubules.

There are three layers of smooth muscle in the vas deferens.
There is an inner longitudinal, a middle circular, and an outer
longitudinal.

The bulbourethral glands are also called Cowper's glands. The
bulbourethral glands are found in males and are homologous to
the Bartholin's glands in females.

The male genital duct system contains: rete testes, tubuli recti,
ductuli efferentes, ductus epididymidis, and ductus deferens.
The male accessory glands contain the bulbourethral glands,

The prostate is made of compound tuboloalveolar glands.

The glands of the prostate lie in a fibromuscular stroma. It is
also referred to as a fibroelastic stroma. There are bundles of
smooth muscle within dense irregular connective tissue.

The bulbourethral glands are also called Cowper's glands. The
bulbourethral glands are found in males and are homologous to
the Bartholin's glands in females
