GENERAL HISTOLOGY

Detailed explanation-1: -The accessory glands, including the seminal vesicles and the prostate gland, provide fluids that lubricate the duct system and nourish the sperm.

Detailed explanation-2: -Prostate gland: The prostate gland is a walnut-sized structure that’s located below the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also help to nourish the sperm.

Detailed explanation-3: -Sulfate chemicals in semen help prevent the sperm cells from swelling, and fructose is the main nutrient to sperm cells.

Detailed explanation-4: -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-5: -Sperm production in the testes takes place in coiled structures called seminiferous tubules. Along the top of each testicle is the epididymis. This is a cordlike structure where the sperm mature and are stored. The release process starts when the penis fills with blood and becomes erect.
