Concept:Mammalian semen includes fluids from several accessory glands, each contributing substances that support sperm survival.
Explanation:The female vagina is naturally acidic, which can damage sperm cells.
The prostate gland secretes an alkaline component of the seminal fluid.
This secretion helps to raise the pH of the fluid in the female reproductive system.
A less acidic environment protects sperm and increases the chance of successful fertilization.
The Cowper's gland mainly produces a lubricating mucus, while the seminal vesicle adds fructose and some fluid.
The vas deferens is a sperm duct, not a gland that secretes seminal fluid.
Therefore, the gland responsible for raising the pH is the prostate gland.
Answer:B. Prostate gland
