2. Function of Sertoli cell Availability of nutrients and supports
phagocytosis of discarded spermids cytoplasm
Regulation for the release of spermatozoa
Secreteion of
tubular fluid
androgen-binding protein (ABP)
inhibin which regulates hormone production
Form a part of the blood-testis barrier
Availability of nutrients and supports

3. Blood-Testis Barrier * endothelium of capillary * basement membrane
* connective tissue
of spermatogenic epith
* tight j. of Sertoli cell

5. Interstitial area of Testis
* ~ 34% of total volume
* L.C.T with enriched blood
and lymphatic vessels
* Leydig cells :
- large, ovoid acidophilic
- round nucleus with
dispersed chromatin
- apparent nucleoli
- secrete androgen

6. Tubule rectus & Rete testis
* no spermatogenic cells
* replacement with
simple cuboidal epi.

7. Epididymis *serious tubules connecting rete testis and ductus deferen
* three parts:
-head: ductuli efferentes
-body
-tail
* functions as accumulation,
storage and maturation of
spermatozoa
ductus epididymidis

8. Ductuli efferentes * 8-12 convoluted ducts connecting with rete testis
* a single layer of epithelial
cells with two types:
- tall columnar & cilliated c.
- short non-ciliated c.

9. Ductus epididymidis single duct pseudostratified epith. of
uniform height
sterocilia (microvilli）
abundant smooth muscles
function of absorption and
secretion

11. Ductus deferens Mucosa Muscularis: Adventitia:
Epith.：pseudostratified columnar epith.
Mucosa
Lamina propria: C.T with enriched elastic f.
3 layers of S.M.,
inner & outer layers: longitudinal,
middle layer: circumferential .
Muscularis:
Adventitia:
fibrosa

13. Prostate * An aggregative of 3 group of glands Mucosal gland
Submucosal gland
Main prostate gland
* Epith. ranges from
simple cuboidal-columnar
to pseudostratified columnar
* embeded within a
fibromuscular stroma
