1 Male Reproductive System
2 Constitution of male reproductive system Genital gland ----testis Genital ducts epididymis / ductus deferens / urinary duct Accessory sex glands Penis prostate gland Seminal vesicle Bulbo-urethral glands
3
4 Testis * producing spermatozoa * Producing hormones
5 *tunica albuginea * mediastinum testis * testicular lobule * seminiferous tubules * tubulus rectus * rete testis
6
7 Seminiferous tubules: * the site of germatozoon production * total of tubules about 600 M * 66% of the testicular volume Interstitial area: *testicular interstitial cells which produce testosterone *connective tissue ; capillary
8 seminiferous tubule Spermatogenic epithelium *Spermatogenic cell: *sustenacular cell (Sertoli cell): basement membrane myoid cell
9 Stages of spermatogenic cell development Spermatogonium Spermatocytes Base of tubule Spermatogenesis Spermatids Spermatozoon Lumen of tubule
10 Spermatogonium *at the base of epithelium *two types -type A type Ad: maintains the germ cell pool type Ap -type B developed primary spermatocytes
11 Primary spermatocyte *the largest germ cell (18 µm in diameter) *large nuclei with chromosome
12 Secondary spermatocyte *hardly identify in sections due to short 2th meiotic division
13 Spermatid * close to the lumen * with half number of chromosomes
14
15 Spermatozoon consisting of two main components. head: nucleus with condensed chromatin acrosome tail: neck middle piece principal piece end piece
16
17 Structure of spermatozoon tail neck------centriole middle piece: * 9+2 arrangement of microtubule *nine coarse fibers arranged longitudinally *mitochondrial sheath principal piece longest portion axoneme a sheath of circumferential fiber end piece only axoneme
18 Sa Sb spermatogonium chromosome Per cell 46 chromatids per chromosome 2 Primary spermatocyte Secondary spermatocyte Spermatid 23 1 spermatozoon 23 1
19 Spermatogonium Spermatocytes Spermatogenesis Spermatids Spermiogenesis Spermatozoon
20
21 Main change during the spermiogenesis * nucleus condensed and elongated * Golgi apparatus becomes acrosome vesicle and forms the acrosome * centrioles elongate to form a flagellum * mitochondria migrate around the flagellum * removing excess cytoplasm
22 Sustentacular cell (Sertoli cell) * irregular outline of cell * nucleus with an definite nucleoli * Its cytoplasm extends to the lumen of the seminiferous tubule
23 Sustentacular cell * enriched organelles * bound to one another by tight junction which separates the tubule into two compartments: * luminal compartment * basal compartment
24 spermatid Secondary Spmatocyte Sertoli cell Primay Spmatocyte spermatogonium
25 Function of Sustentacular 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
26 blood-testis barrier * endothelium of capillary * basement membrane of capillary * connective tissue * basement membrane of spermatogenic epithelium * tight junction of Sustentacular cell
27 Interstitial area of testis * Contains loose connective tissue with rich blood and lymphatic vessels * Testicular interstitial cell: - large, ovoid acidophilic Cell - round nucleus with dispersed chromatin and apparent nucleoli - secrecte androgen
28 Tubule rectus & Rete testis *no spermatogenic cells *simple cuboidal epithelium
29
30 Epididymis * divided into three parts: head: efferent duct body epididymal duct tail * functions as accumulation, storage and maturation of spermatozoon
31
32 Efferent duct * connecting with rete testis * lining by a single layer of epithelial cells which have two different types: - tall columnar & cilliated cell - short non-ciliated cell
33 Epididymal duct pseudostratified epithelium of uniform height sterocilia (microvilli) abundant smooth muscles function of absorption and secrection
34 Prostate * An aggregative of 3 group of glands Mucosal glands Submucosal glands Main prostate glands * The epithelium ranges from simple cuboidal-columnar to pseudostratified columnar * The glands are embeded within a fibromuscular stroma
