Seminal fluid (also known as, semen)
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.
YES.sperm duct add fluid with sperm to the testes from epididymis.
Testicles and prostate.
The testes and the prostate add fluid to semen
When glands add fluids, they typically produce substances such as hormones, enzymes, mucus, or saliva. The specific type of fluid produced depends on the type of gland and its function in the body.
Glands add fluids to sperm in the male reproductive system, specifically the seminal vesicles, prostate gland, and bulbourethral glands. These fluids contain nutrients, enzymes, and other substances that help nourish and protect the sperm, as well as aid in their motility and ability to fertilize an egg.
The seminiferous tubules do not add secretions to seminal fluid. They are responsible for producing sperm cells through spermatogenesis, but they do not contribute any secretions to the seminal fluid.
In males, there are 3 different sets of glands involved. The testes create sperm cells. The bulbourethral glands and the prostate glands add extra fluids to nourish the sperm cells and make them more mobile.

The prostate gland secretes about 30% of the fluid, which mixes with the fluid from the seminal vesicle and the spermatozoa. The spermatic fluid or semen is formed by the secretions of the Testes, Seminal vescicles, Prostate gland and Bulbourethral gland. The sperms are secreted by the testes which pass through the vas deferns to seminal vescicles. The seminal vescicles contibute to about 70% of semen. The prostate gland and bulbourethral gland(Cowper's gland) further contibute to form semen.
Composition of human semenDuring the process of 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. The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen.[1] The prostatic secretion, influenced by dihydrotestosterone, is a whitish (sometimes clear), thin fluid containing proteolytic enzymes, citric acid, acid phosphatase and lipids.[1] The bulbourethral glands secrete a clear secretion into the lumen of the urethra to lubricate it.[2] Sertoli cells, which nurture and support developing spermatocytes, secrete a fluid into seminiferous tubules that helps transport sperm to the genital ducts. The ductuli efferentes possess cuboidal cells with microvilli and lysosomal granules that modify the semen by reabsorbing some fluid. Once the semen enters the ductus epididymis the principle cells, which contain pinocytotic vessels indicating fluid reabsorption, secrete glycerophosphocholine which most likely inhibits premature capacitation. The accessory genital ducts, the seminal vesicle, prostate glands, and the bulbourethral glands, produce most of the seminal fluid.Seminal plasma of humans contains a complex range of organic and inorganic constituents.The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract. The normal environment of the vagina is a hostile one for sperm cells, as it is very acidic (from the native microflora producing lactic acid), viscous, and patrolled by immune cells. The components in the seminal plasma attempt to compensate for this hostile environment. Basic amines such as putrescine, spermine, spermidine and cadaverine are responsible for the smell and flavor of semen. These alkaline bases counteract the acidic environment of the vaginal canal, and protect DNA inside the sperm from acidic denaturation.(Source wikipedia)Semen is made up mostly of seminal fluid, which is a combination of dead epithelial cells, fructose, mucus, proteins, and enzymes and prostatic fluid, which is white milky mucus and contains prostate specific antigen, proteolytic enzymes, acid phosphotase and lipids. The Cowper's glands add a clear fluid.
Firstly, sperm are cells, you can't see them with your unaided eyes. I guess you are talking about semen, which is the medium in which sperm travels. Ok, semen is mostly water, actually. A number of glands (like the cowper, prostate) add their contributions along the way. The role of semen is to transport the sperm cells deep within the uterus/fallopian tubes of the female, and to protect the sperm from the acidic nature of that anatomy.
