Final answer:
Seminal fluid nourishes and protects sperm by providing nutrients like fructose for energy, pH buffering to neutralize vaginal acidity, and zinc for maintaining sperm quality. It is produced by accessory glands of the male reproductive system, primarily the seminal vesicles, prostate gland, and bulbourethral gland.
Step-by-step explanation:
Function of Seminal FluidThe function of seminal fluid is to provide a nutritive and protective medium for sperm during its journey through the male reproductive tract, out of the body, and into the female reproductive tract. Seminal fluid, largely contributed by the accessory glands such as the seminal vesicles, prostate gland, and bulbourethral gland, contains nutrients like fructose which provides energy to sperm. Moreover, it offers pH buffering to protect sperm against the acidic environment in the female vagina, thus prolonging their lifespan and enhancing their motility. The prostate gland specifically secretes a slightly alkaline fluid that makes up about 30 percent of semen's total volume, which is rich in zinc and important for maintaining sperm quality.
The function of seminal fluid is to provide nutrients and support for sperm. Seminal fluid, which is a mixture of sperm and glandular secretions, carries the sperm through the urethra and out of the body. The secretions in semen contain important compounds for the survival and motility of sperm, including nutrients, electrolytes, and pH buffer.For example, seminal fluid contains high concentrations of the sugar fructose, which is the main source of energy for sperm. It also contains alkaline substances that help neutralize the acidic environment in the female vagina, protecting the DNA in sperm and prolonging their lifespan in the female reproductive tract.
