So let's suppose that during sexual intercourse this male individual ejaculates and what that means is the sperm cells will be released from the epididymus and they will travel along the following canal shown in blue and this canal is known as the VAS deference. Now the VAS deference ultimately empties out into a smaller canal shown in red known as the ejaculatory duct. And the ejaculatory duct is found next to an accessory gland known as the seminal vesicle. Now what the seminal vesicle does is it releases a fluid substance that contain nutrients such as fructose and proteins that are needed by the sperm cells. So when the sperm cells enter the ejaculatory duck they mix with that fluid that is produced by the seminal vesicle and then that fluid travels into our urethra. This canal shown in purple.
