When semen comes out from testis then can i think the epedermal path is normal?

Unclear question: Sperm/semen travels from the testes via, epididymus, vasdeferens, seminal vescicles, prostate and urethra.

Male Anatomy: If you are having normal ejaculation with sexual stimulation i would believe that your anatomy is thus normal. I am not quite sure what your question is really asking beyond that.

Am I understanding?: If you ejaculate, all you know is that you have a straight path from the prostate and seminal vesicles outward. It tells you nothing about whether a vas or epididymis is obstructed. Your testes produce sperm at a constant rate and send them on. If they produced semen, they'd get smaller after ejaculation -- and of course they don't.
