Prostate:

Composed of three zones: Central, peripheral, transitional

Constitutes 70% of human ejaculate

Fructose is main product of secretion

Glands produce prostatic fluid

� Its branched tubuloalveolar glands emptying into prostatic urethra

� Its glands are lined with columnar pseudostratified epithelium

Is surrounded by fibroelastic capsule rich in smooth muscles that form septa

Seminiferous epithelium (SE)

Contains germ cells and Sertoli cells.

Germ cells are divided into spermatogonia, spermatocytes and spermatids

Germinal cells are physically supported by Leydig cells

Sertoli cells are supporting cells

Spermatogonia include spermatogonia Ad, Ap, B.

Spermatogonia Ad in man are spermatogonial stem cells

Spermatocytes include primary and secondary

The blood-testis barrier (BBT)

Divides the seminiferous epithelium into two compartments: basal and adlumina

Each compartment contains favourable microenvironment for germ cells

Is created between the capillaries within the seminiferous epithelium

Is created by occluding junctions between cytoplasmic processes of Sertoli cells

Isolates the haploid germ cells from own immunological system

Within adluminal compartment are primary and secondary spermatocytes, spermatids

� Within the basal compartment spermatogonia and preleptotene spermatocytes are located

Seminiferous tubule

Is composed of seminiferous epithelium and lamina propria

Leydig cells are located between germ cells of the epithelium

Seminiferous epithelium contains germ cells and Sertoli cells

Seminiferous epithelium is pseudostratified

Sertoli cells of seminiferous epithelium are supporting cells

There are no blood vessels

There are no lymphatic vessels in tubule

Tubules are convoluted and have the form of loops

Interstitial tissue of testis

Contains endocrine interstitial gland

Contains lymphatic vessels

� Does not contain lymphatic vessels

Is found between seminiferous tubules

Leydig cells

Are controlled by FSH

� Located in interstitial tissue of testi

Produce testosterone

Produce dihydrotestosterone

Supporting cells in seminiferous epithelium

Spermatogenesis

� Is process formation of spermatozoa.

Process formation of spermatozoa

Spermatogenesis in man lasts 74 days

Spermatogonia Ad undergo modification in spermiogenesis

� Spermatids undergo modification in spermiogenesis(dont know actually)

Epididymis:

� Each part is lined with pseudostratified columnar epithelium with stereocilia

In the epididymis, spermatozoa are coated by glycoproteins to mask haploid antigens on the surface of spermatozoa

Is divided into head, body, tail

The caput is place of spermatozoa maturation

Sertoli cells:

Are type of germ cells(somatic)

Are supporting cells in seminiferous epithelium

Produce dihydrotestosterone (DHT

Undergo mitosis during prenatal life

Produce the anti-Müllerian hormone (AMH).

Support the development of germ cells into spermatozoa.

Undergo mitosis during prenatal life.
