Semen. Seminal vesicles are small glands in males that are located just below the bladder. They secrete about 50-70% of the fluid that ultimately becomes semen.
Sem Ves. Is a storeage depot for semen, sperm + prostatic secretion, residing at the base of the prostate, below or behind the bladder, in front of the rectum. It constricts and shoots semen during ejaculation, and can be directly invaded by prostate cancer. I don't know what a sem gland is.
Here are some, but. Behind what we know always hides something we still don't know. Up to now, prostate gland is known to provide fluid as the major part of semen to nurture & protect sperms, Cowper's gland is inside the posteriolateral aspect of the wall of membranous urethra, and seminal vesicles are to store semen and will contract coherently to ejaculate the semen outward.
