Hmm..It was just a wild guess..actually B and C are the same..so it can't be the right choice..
and seminal vesicles i think the main source for seminal fluid..and need for sperm..But i am not sure how they help for production of sperm..
Anyway mjl1717,i think you have already finished your exam with good score..I read all of your posting..and i learned so many things from your posting..
thanks

Seminal vesicles produce most of sperm. Vas defferens is only a channel for spermatoz. transport from testis and epidydymis to prostate

there are 2 types of options in the choices 1) accessory glands in the male reproductive system - seminal vesicles, cowper's glands 2) genital ducts these should primarily be concerned with transportation from seminiferous tubules (main production, maturation site) to the exterior. seminal vesicles give energy to the sperm by adding fructose to the semen. I don't know if the cowper's glands help in the production of the sperm - thought they were the oiling system (lubrication). but since this is a MCQ test, 2 names for the same thing automatically rules it out. so, vas deferens - which should be carrying sperms towards the urethra - is the correct answer. that's the best I can think of.
