Male Reproductive System 1
What are the purposes of the structures of the male reproductive system?
- produce and nourish sperm (gametes) and protective fluid (semen)
- nourish sperm
- transport sperm and semen
- deliver (discharge) sperm within the female reproductive tract
- produce and secrete male sex hormones
What are the male external genitalia?
- scrotum (covers testes)
What are the male internal reproductive organs?
- seminiferous tubules
- vas dererens
- ejaculatory duct
What are the male accessory glands?
What are the testes, and where are they housed?
paired oval glands that produce sperm
housed outside the abdominal cavity in the scrotum
Why are the testes located outside the body in the scrotum?
Since sperm cannot develop at normal body temperature, locating them outside the body keeps them cool enough for sperm to develop
Can sperm develop at normal body temperature?
No. That's why they are located outside the body in the scrotum, where it is cooler than body temperature.
Where is the epididymis located, and what is its function?
- located inside scrotum, one behind each testis
- stores sperm produced by testis
Where are seminiferous tubules located and what is their function?
- located inside epididymis
- site of sperm maturation
What is the vas deferens, where is it located, and what is its function?
- long muscular tube (duct) leading from epididymis into pelvic cavity
- transports mature sperm to the urethra in preparation for ejaculation.
How is sperm moved along the vas deferens to the urethra?
propelled by muscular contractions of the vas deferens muscles
