What is the estimated daily sperm production in males?
45m sperm per day
This figure refers to the typical sperm output in a healthy male.
How much testosterone do males produce and secrete daily?
3-10mg testosterone per day
This range represents the average testosterone secretion in healthy males.
Where does sperm production occur?
Seminiferous tubules
These are located within the testes.
What is the function of the epididymis?
Sperm mature & become motile
The epididymis is a coiled tube approximately 6cm long.
What is the vas deferens?
Passage from testes to seminal vesicle
It serves as a conduit for sperm transport.
Fill in the blank: The site of sperm production is the _______.
seminiferous tubules
True or False: Sperm are produced in the epididymis.
False
Sperm are produced in the seminiferous tubules, not the epididymis.
What is the approximate length of the epididymis?
6cm long
What process occurs in the seminiferous tubules?
Sperm production
Sperm are initially immature and immotile in this location.
What do seminal vesicles produce?
Seminal fluid, which is alkaline and contains fructose (60% of semen)
Seminal vesicles join with the vas deferens to form the ejaculatory duct.
What is the function of the prostate?
Produces prostatic fluid, which is white and contains clotting enzyme (30% of semen)
The prostate completely surrounds the area of the male urethra.
What is the common pathway for urine and semen?
Urethra
Urine and semen cannot pass at the same time due to sphincters.
True or False: The seminal vesicles produce 30% of semen.
False
Seminal vesicles produce 60% of semen.
Fill in the blank: The seminal vesicles join with _______ to form the ejaculatory duct.
vas deferens
What type of fluid does the prostate produce?
Prostatic fluid
This fluid is characterized by its white color and the presence of a clotting enzyme.
What prevents urine and semen from passing at the same time?
Sphincters
corpus carvenosa
run on either side of the penis and spongiosum houses the urethra
what is the urethra
passage of urine and semen
glans penis
most sensitive element
prepuce
