Final answer:
The seminal gland, also known as the seminal vesicle, is responsible for secreting fructose to nourish sperm. This gland contributes a significant portion of the semen volume and the fructose necessary for sperm vitality and motility.
Step-by-step explanation:
Which Gland Secretes Fructose in Semen?
The gland that secretes fructose to nourish sperm is known as the seminal gland or seminal vesicle. Fructose is a crucial energy source for sperm and is part of the seminal fluid that aids in sperm motility and vitality within the female reproductive tract. The seminal vesicles produce a thick, yellowish, alkaline solution that contains mucus, fructose, coagulating enzyme, ascorbic acid, and prostaglandins, which account for about 60 percent of the bulk of semen. It is important to note that other glands like the prostate and the bulbourethral gland also contribute components to semen, but the seminal vesicles are primarily responsible for the fructose content.
