Seminal fluid (also known as, semen)
YES.sperm duct add fluid with sperm to the testes from epididymis.
Testicles and prostate.
The testes and the prostate add fluid to semen
seminal vesicle
No, Cowper's glands do not contain sperm. Cowper's glands, also known as bulbourethral glands, produce a clear fluid that helps to lubricate the urethra and neutralize acidity in the urethra prior to ejaculation.
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 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.
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 seminal vesicles, prostate gland, and the bulbo-urethral glands (known as 'Cowper's glands').
I think its the seminiferous glands
