The glands that add other fluids to the sperm to make semen are located in, or near, the prostate gland. One of these is the bulbourethral gland.
Prostate gland
Seminal fluid (also known as, semen)
YES.sperm duct add fluid with sperm to the testes from epididymis.

The testes and the prostate add fluid to semen
seminal vesicle
Semen is the fluid that contains sperm cells, (sperm cells don't secrete fluid). During ejaculation sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen.
Bulbourethral glands
the seminal vesicles, prostate gland, and the bulbo-urethral glands (known as 'Cowper's glands').
I think its the seminiferous glands
The glands that produce a fluid component of seminal fluid are called seminal vesicles. They also lubricate and nourish the sperm.
The seminal vesicles are a pair of glands. Each opens into the vas deferens. These glands secrete many of the components of semen, but all "seminal fluid" is not semen. Seminal vesicle fluid is typically ejaculated first. Semen, which is simply fluid is the primary ejaculate, but semen is NOT sperm. Only occasionally will sperm be found in the seminal vesicles, but millions of sperm are found in the fluid called semen. When the seminal vesicle fluid contains some sperm, this sperm has lower motility and very poor survival. The sperm in semen, though, should show high motility and survival rates.
