PATHOLOGY

Detailed explanation-1: -The sperm move into the epididymis, where they complete their development. The sperm then move to the vas deferens (VAS DEF-uh-runz), or sperm duct. The seminal vesicles and prostate gland make a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated.

Detailed explanation-2: -Composition. Most of the fluid in semen is made up of secretions from male reproductive organs. Semen contains citric acid, free amino acids, fructose, enzymes, phosphorylcholine, prostaglandin, potassium, and zinc.

Detailed explanation-3: -How the Urethra Works. During ejaculation the sperm cells, seminal vesicle fluid and prostate fluid enter the urethra (the tube in the penis through which urine and seminal fluid leave the body).
