What storage sacs for sperm and seminal fluid empty into the urethra at the prostate?

The seminal vesicles are specialized glands located near the prostate that play a crucial role in male reproductive health. They produce a significant portion of the seminal fluid that nourishes and helps transport sperm during ejaculation. The fluid from the seminal vesicles is rich in fructose and other nutrients, which provide energy for the sperm.

These glands empty their contents into the urethra at the junction of the urethra and the prostate gland. This process is essential because during ejaculation, the sperm from the testes mix with the seminal fluid from the seminal vesicles, as well as secretions from the prostate, to form semen. This mixture is then expelled through the urethra.

Other options like the ovaries are relevant to female reproduction, the scrotum is a pouch that contains the testicles but does not store sperm, and the epididymis is a coiled tube where sperm mature but does not produce seminal fluid. Thus, the seminal vesicles are the correct structures that specifically provide the storage and secretory function needed for sperm transport.
