Final answer:
Seminal fluid provides nutrients, electrolytes, and pH buffering for sperm. It does not provide hormones directly, but the male reproductive system releases testosterone.
Step-by-step explanation:
The function of seminal fluid is to provide important compounds for the sperm including nutrients, electrolytes, and pH buffering. Seminal fluid is produced by the accessory glands in the male reproductive system, such as the seminal vesicles, prostate gland, and bulbourethral gland. These secretions support the survival and motility of sperm by providing a medium for swimming, supplying energy through high concentrations of the sugar fructose, and neutralizing the acidic environment in the female vagina.
Hormones are not directly produced by the seminal fluid itself, but instead, the male reproductive system releases the male sex hormone testosterone, which is important for sexual development and maintaining normal spermatogenesis after puberty.
