Which of the following is found in high amount in seminal plasma?

Fructose and calcium .

The correct answer is Option (1) - Fructose and calcium .

The male accessory glands consist of the seminal vesicles, prostate gland, and bulbourethral glands. These glands produce fluids that combine to form seminal plasma, a component of semen. Here’s a brief breakdown of their roles:

1. Seminal vesicles: These paired glands secrete a fluid rich in fructose, which provides energy for sperm. Their secretion also contains enzymes and other substances that help nourish and support sperm viability.
2. Prostate gland: The prostate adds secretions that contain calcium and enzymes. These substances help in sperm activation and enhance sperm motility.
3. Bulbourethral glands: These paired glands secrete a clear, lubricating fluid that neutralizes any acidic residue in the urethra, making the passage smoother for sperm during ejaculation.

Together, the secretions of these glands contribute to semen, which supports, nourishes, and transports sperm, aiding in successful fertilization.
