Name all ducts that the sperm follow in order from the time they form in the testes to the time of ejaculation -

In detail, from the beginning to the ejaculatory end...
Spermatozoa are produced in the four layers of the Seminiferous ducts.
The immature sperm, once they break free, pass along the seminiferous ducts which join with other seminiferous ducts to form the efferent ducts that conduct the newly formed sperm cells into the epydidimus where they are nurtured to grow and mature. It is in the epydidimus that the tails start to become useful for mobility.
At ejaculation, the sperm travels from the epydidimus through the vas deferens to the prostate, where they are mixed with ejaculatory fluids produced by the seminal vessicles and the prostate. The ejaculate then passes into the prostatic portion of the urethra, between the pre-prostatic sphincter at the base of the bladder and the prostatic sphincter at the base of the prostate.
The pathway from this point onward is along the urethra, until the semen (a mixture of sperm -1%-, prostatic fluids -30%- and seminal vessicle fluids -about 70%- is pushed by rhythmic muscle contractions to the tip of the penis where it leaves the man-s body.
Summary:
1. Seminiferous tubules: sperm made here
2. Efferent ducts: sperm gathered here
3. Epydidimus: sperm matures here
4. Vas Deferens: sperm moves to prostate through here
5. Urethra: sperm and seminal fluids (mixed) leave the body through here.

why would you want to know that you sick little girl???????
Craftsman gave you the right answer, but if you need
a more vivid detail call me!
It starts in the seminal ducts in the testicles, then it goes through the Vas Deferens, and finally gets to the urethra, where it is expelled from the penis. At least I think that-s how it goes. You can always find good information on Wikipedia if you need more.
