The seminal vesicle is not a paired gland. It is a single, midline structure located behind the bladder in males and plays a crucial role in producing seminal fluid that nourishes and transports sperm.
Seminal vesicle, prostate gland, bulbourethral (or Cowper's) glands
Prostate gland Seminal vesicle Cowper's gland
The prostate gland is unpaired, as it is a single gland located below the bladder in males. The vas deferens, seminal vesicles, and bulbourethral glands are paired structures in the male reproductive system.
The male reproductive system includes: bulbourethral gland, epididymis, seminal vesicle and prostate gland.
Several glands are involved in producing semen. The testes create the sperm cells. The prostate gland creates most of the liquid in the semen. The cowper's glands also produce some of the liquid. The seminal vesicles hold the mixture until ejaculation.
The seminal vesicle ducts empty into the ejaculatory ducts. These ducts are formed by the merger of the seminal vesicle ducts and the vas deferens. The ejaculatory ducts then pass through the prostate gland and open into the urethra, contributing to the semen during ejaculation.
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.
The prostate, testes, and seminal vesicles
The prostate gland is a small gland located below the bladder and in front of the rectum that produces fluid that makes up semen. The seminal vesicles are a pair of small glands located behind the bladder that produce fluid that nourishes and transports sperm. Both glands play a role in the production of seminal fluid but are located in different parts of the male reproductive system.
The tube that carries semen into the prostate gland is called the ejaculatory duct. This duct is formed by the union of the vas deferens and the seminal vesicle duct, and it passes through the prostate gland before emptying into the urethra. The ejaculatory duct plays a crucial role in the male reproductive system by transporting sperm and seminal fluid to be ejaculated during sexual intercourse.
Sperm cells need to be bathed with fluids from the prostate gland and seminal vesicle. The seminal glands supply fluid that carries the sperm along and the seminal vesicle supplies fluid that helps the sperm to survive better in the vagina.
