compartments
each testis has about 250 compartments called testicular lobules
where is sperms produced
each lobule contain 1-3 highly coiled seminiferous tubules on which sperms are produced
what are the 2 types of seminiferous tubule
2 types of cells
—->male germ cell or spermatogonia
—->sertoli cells
male germ cells function
undergo meiotic division leading to sperm formation
sertoli cells or nurse cells
provide nutrition to germ cells
what are Leydig cells
the region outside seminiferous tubule is called interstitial spaces that contain small blood vessels and interstitial cells or leydig cells
function of leydig cells
synthesise and secrete testicular hormoes called androgens
what are male sex accessory ducts
rete testis, vasa efferentia, epididymis and vasa deferens
function of ejaculatory duct
store and transport the sperms from testis to the putside through urethra
what does accessory glands inculde?
A pair of seminal vesicle
a prostate gland
A pair of bulbourethral gland
what is seminal plasma rich in
fructose, calcium and certain enzymes
what does bulbourethral gland helps in
lubrication of penis
male external genitalia
