1. Seminal vesicles: These are two small glands located behind the bladder. They produce a thick, yellowish fluid that makes up about 60% of the seminal fluid. This fluid is rich in fructose, which provides energy for sperm, and prostaglandins, which help with sperm motility.
2. Prostate gland: This gland, shaped like a walnut, surrounds the urethra just below the bladder. It produces a milky white fluid that makes up about 30% of the seminal fluid. This fluid contains enzymes that activate sperm and help to neutralize the acidity of the female reproductive tract.
3. Bulbourethral glands: These are two small glands located near the base of the penis. They produce a clear, slippery fluid that makes up about 5% of the seminal fluid. This fluid helps to lubricate the urethra and neutralize any remaining acidity.
Together, the secretions from these three organs combine to form seminal fluid, which nourishes, protects, and transports sperm during ejaculation.
