What helps to produce seminal fluid?

Answer 1

The seminal vesicles are a pair of glands. Each opens into the vas deferens. These glands secrete many of the components of semen, but all "seminal fluid" is not semen. Seminal vesicle fluid is typically ejaculated first. Semen, which is simply fluid is the primary ejaculate, but semen is NOT sperm. Only occasionally will sperm be found in the seminal vesicles, but millions of sperm are found in the fluid called semen. When the seminal vesicle fluid contains some sperm, this sperm has lower motility and very poor survival. The sperm in semen, though, should show high motility and survival rates.
