***Male Reprod video...https://youtu.be/bHBDdmj1yIs
***Male accessory glands (MAG) in humans are the seminal vesicles, prostate gland, and the bulbourethral glands (also called Cowper's glands)

***The prostate is a walnut-sized gland located between the bladder and the penis. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body.

The prostate secretes fluid that nourishes and protects sperm. During ejaculation, the prostate squeezes this fluid into the urethra, and it’s expelled with sperm as semen.

***The secretions produced by the Cowper's glands help to protect sperm as it passes through the urethra during ejaculation. In response to sexual stimulation prior to ejaculation, the Cowper's glands begin producing an alkaline mucous secretion known as pre-ejaculate
