Male Reproductive System The human male reproductive system consists of gonads called testes, a series of ducts (epididymis, vas deferens, ejaculatory duct, urethra) that serve to transport spermatozoa to the female reproductive tract, and accessory sex glands (seminal vesicles, prostate, and bulbourethral glands).ombined secretions from the seminal vesicles and prostate account for roughly 90 percent of semen volume. The seminal vesicle secretions are rich in fructose (which serves as an energy source for spermatozoa), prostaglandins, and proteins that facilitate clotting of ejaculated semen in the female.

- They are glands, whose secretion constitutes 60-70 % of the ejaculate. The secretory product of the columnar cell, which may be seen in the lumen of the seminal vesicles, is strongly acidophilic. It contains large amounts of fructose which the spermatozoa utilise as a source of energy.he seminal vesicles develop from the vas deferens. Their histological organisation resembles to some extent that of the vas deferens. They are elongated sacs (about 4 cm long and 2 cm wide) , which taper where they unite with the vas deferens. Each seminal vesicle consists of one coiling tube (about 15cm long) .

- Then the sperm travels to be stored in the epidydimus, which is a large, coiled-up tube outside the testicles, but still inside the scrotum (sac). This is where they are stored until needed. As needed, the sperm cells travel through a pair of tiny tubes called the vas deferens (Hence the term,'vas-ectomy').The sperm enter the stream of semen near the urethra, or urinary tube.his is where they are stored until needed.

Male Reproductive System Seminal vesicles: The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a source of energy to help them move.

Human Physiology/The male reproductive system The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epidrimys, vas deferens, ejaculatory duct and urethra.

- Vas deferens. The vas deferens (or ductus deferens) is a duct in a man’s body. It is also present in other male vertebrates. Its function is to carry sperm away from the testes, towards the penis. There are two of these ducts, which are tubes surrounded by smooth muscle.

Male Reproductive System contains a 20 ft coiled tube called the ductus epididymis that runs from the head to the body to the tail. Vas Deferans. transport sperm from the tail of the epididymis to the ejaculatory duct. 18 in. long, by peristalsis, it is a part of the spematic cord.

- Grilling might just be the best way to cook up a skirt steak. The intense heat gives the succulent and flavorful cut a rich char that’s smoky and crisp at the edges. The trick is to get the fire hot enough and dry off any marinade before placing the meat on the grill. This will give you the deepest sear.

- In the male embryo, each testis connects through a series of tubules to the mesonephric duct. During further development, the connecting tubules become the seminiferous tubules, and the mesonephric duct becomes the efferent ductules, epididymis, ductus deferens, ejaculatory duct, and the seminal vesicle.arly in fetal development (the tenth thought the twelfth week), sexual distinction of the external genitalia becomes apparent. In the male, the phallus enlarges and develops into the glans of the penis. The urethral folds fuse around the urethra and become the erectile tissue that forms the body of the penis.

Vas deferens Structure [edit]. There are two ducts, connecting the left and right epididymis to the ejaculatory ducts in order to move sperm. Each tube is about 30 centimeters (1 ft) long (in humans), 3 to 5 mm in diameter and is muscular (surrounded by smooth muscle). Its epithelium is lined by stereocilia. They are part of the spermatic cords.

Reproductive System The epididymis and the vas deferens make up the duct system of the male reproductive organs. The vas deferens is a muscular tube that passes upward alongside the testicles and transports the sperm-containing fluid called semen. The epididymis is a set of coiled tubes that connects to the vas deferens.

- Sperm cells that are stored in the male body are not capable of self-movement because of the acidity of the accompanying fluids. When the sperm receive fluids, called seminal plasma, from the various internal accessory organs (prostate gland, ejaculatory ducts, seminal vesicles, and bulbourethral glands []), the acidity decreases. As they leave the body, the sperm receive oxygen, which is vital to motility.

Testis Sperm travels through the testis from the tubules, through a network of ducts called the rete testis, to the epididymis. One of the most common complications that can occur with the testes is an undescended testis, which typically occurs in about two to four percent of all male infants and around thirty percent of boys born prematurely.

Fertilization Sperm transport. sperm flagellum assist, channels in the cervical mucus help direct the sperm, muscular contractions of the uterine channel assist, sperm have 50% chance of making it into the correct tube, Eddy currents created by the cilia movements assist the sperm through the uterine and uterine tube.vulation steps. Follicle wall breaks down (enzymatic breakdown that causes the follicle to collapse), oocyte is expelled into perotoneal cavity (with zona pellucida, corona radiata, and cumulus cells), oocyte complex is picked up by uterine tube (cilia).

- Answer by Muzik101. Confidence votes 83. After sperm is produced, it travels through the testes through sperm ducts. that circle the bladder, a gland called the seminal vesicle provides sperm with a. fluid. This fluid supplies the sperm with an energy source and helps them move.
