Full Answer
The male urethra is an 18-22 cm long muscular tube that conveys urine from the urinary bladder. Hence it runs from the internal urethral orifice of the bladder to the external urethral orifice located at the tip of the glans penis.
Unlike a woman, most of a man’s reproductive system is located outside of his body. These external structures include the penis, the scrotum, and the testicles.
Producing and secreting male sex hormones The urethra, which is part of both the male reproductive system and the urinary system, has the dual function of transporting sperm and urine. Components of the Male Reproductive System
c. The bulbourethral glands enter the spongy urethra at the base of the penis. d. The prostate gland contains smooth muscle partitions covered with columnar epithelium. e. The seminal vesicles are sac-shaped glands located next to the ampullae of the ductus deferentia.
Prostate. The prostate gland is a firm, dense structure that is located just inferior to the urinary bladder. It is about the size of a walnut and encircles the urethra as it leaves the urinary bladder. Numerous short ducts from the substance of the prostate gland empty into the prostatic urethra.
The prostate is a walnut-sized exocrine gland that borders the inferior end of the urinary bladder and surrounds the urethra. The prostate produces a large portion of the fluid that makes up semen.
prostate glandprostate gland, chestnut-shaped reproductive organ, located directly beneath the urinary bladder in the male, which adds secretions to the sperm during the ejaculation of semen. The gland surrounds the urethra, the duct that serves for the passage of both urine and semen.
Cowper's glands are pea sized glands present inferior to the prostate gland in the male reproductive system. They produce thick clear mucus prior to ejaculation that drains into the spongy urethra.
The prostate gland is located just below the bladder in men and surrounds the top portion of the tube that drains urine from the bladder (urethra). The prostate's primary function is to produce the fluid that nourishes and transports sperm (seminal fluid).
Listen to pronunciation. (eh-pih-DIH-dih-mis) A narrow, tightly-coiled tube that is attached to each of the testicles (the male sex glands that produce sperm). Sperm cells (male reproductive cells) move from the testicles into the epididymis, where they finish maturing and are stored.

Cowper's Gland is also called the bulbourethral gland. It is the smallest exocrine gland of the male reproductive system. The Cowper's glands are responsible for producing a precum fluid called Cowper's fluid that helps to neutralize acidic urine and lubrication of the distal urethra.
They secrete mucus to lubricate the vagina and are homologous to bulbourethral glands in males. However, while Bartholin's glands are located in the superficial perineal pouch in females, bulbourethral glands are located in the deep perineal pouch in males.

The urethra ends at the point where the extremity of the prepuce joins the body of the penis, in a small valve-like opening. The prepuce is also cleft on its under surface and forms a sort of hood over the glans.
The membranous or intermediate part of the urethra is the second shortest part of the urethra that connects the prostatic urethra to the penile urethra. It is 1-1.5 cm long and it is surrounded by the external urethral sphincter.
The male urethra is a pelvic urinary organ that functions primarily as a connecting cord which transports urine from the urinary bladder to the exterior. On the superior end of the bladder is a pair of 25-30 cm long muscular tubes, the ureters, which also connect and fills the bladder with urine formed in the kidneys.
When the penis is in a flaccid (non-erect) state, the urethra presents a double curvature and is divisible into four parts, which are the: Preprostatic (intramural) part. Prostatic urethra. Membranous (intermediate) urethra. Spongy (Penile) urethra.
The initial part, which passes through the bladder musculature (“bladder neck”), just below the internal urethral orifice, is referred to as the pre-prostatic urethra or intramural part of the urethra. Ideally it is about 0.5-1.5 cm in length but varies depending on whether the bladder is filled with urine or empty.
Histology. The wall of the urethra is made up of mucous, submucous and muscular layers. The prostatic urethra is bounded by prostatic tissue, while the penile urethra (spongy urethra) by erectile tissue of the corpus spongiosum.
Early in the 4th week of embryonic development, the urinary system develops. It consists of the urinary system,kidneys, ureters, urinary bladder and the urethra. The urethra is mainly derived from a solid cord of ectodermal cells that grows inward from the tip of the glans penis and joins the rest of the spongy urethra.
Vas deferens: This long, muscular tube carries mature sperm from the epididymis to the urethra prior to ejaculation. The vas deferens joins the urethra just behind the bladder. Ejaculatory ducts: The seminal vesicles and the vas deferens join together to form the ejaculatory ducts, which empty into the urethra.
Tweet. The male reproductive system includes the penis, testicles, urethra, prostate gland, and other structures. Together, they are responsible for making and transporting sperm and producing male sex hormones.
Seminal vesicles: Attached to the vas deferens near the base of the bladder, these sac-like pouches produce a fluid that is rich in sugar (fructose). This fluid, which makes up most of a man’s ejaculatory fluid, helps sperm move (motility) by providing them with a source of energy.
FSH is needed for the production of sperm (spermatogenesis), and LH stimulates the production of testosterone in the testicles. Testosterone plays a role in the development of many male traits, such as muscle strength and mass, bone mass, distribution of fat, and sex drive.
Muscles in the wall of the scrotum can move the testicles toward the body for warmth , or further away to decrease the temperature.
Three main hormones are involved in the functioning of the male reproductive system—testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Both LH and FSH are made in the pituitary gland, which is located at the base of the brain. FSH is needed for the production of sperm (spermatogenesis), ...
Benign prostatic hypertrophy (BPH): BPH refers to enlargement of the prostate gland. This occurs with age and often leads to trouble urinating or the need to urinate in the middle of the night (nocturia). Erectile dysfunction: This is the inability to achieve or maintain an erection sufficient for sexual intercourse.
Most of the male reproductive system is located outside of your abdominal cavity or pelvis. The external parts of the male reproductive system include the penis, the scrotum and the testicles.
The fluid of the seminal vesicles makes up most of the volume of your ejaculatory fluid, or ejaculate. Prostate gland: The prostate gland is a walnut-sized structure that’s located below the urinary bladder in front of the rectum. The prostate g land contributes additional fluid to the ejaculate.
The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes. It’s also the job of the epididymis to bring the sperm to maturity — the sperm that emerge from the testes are immature and incapable of fertilization.
FSH is necessary for sperm production (spermatogenesis). LH stimulates the production of testosterone, which is necessary to continue the process of spermatogenesis. Testosterone is also important in the development of male characteristics, including muscle mass and strength, fat distribution, bone mass and sex drive.
These external organs include the penis, scrotum and testicles. Internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as urination. Urology 216.444.5600.
Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
The scrotum protects your testes, as well as providing a sort of climate control system. For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature.
