What are the male and female reproductive systems?

The male and female reproductive systems are essential for reproduction. The main purpose of the male reproductive system is to produce and deliver sperm into the female reproductive system. The main purpose of the female reproductive system is to produce egg cells and to nurture a fertilized egg so it is able to develop into a fetus.

What are the male reproductive structures?

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.

What are the internal organs of the male reproductive system?

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.

How many testes do men have?

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.

Where are the cowper glands located?

Bulbourethral glands: The bulbourethral glands, or Cowper’s glands, are pea-sized structures located on the sides of the urethra , just below the prostate gland. These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.

What is LH in a male?

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.

Why is testosterone decreasing in men?

This can sometimes be a result of an illness, such as diabetes. It’s unclear whether decreasing testicular function contributes to symptoms like fatigue, weakness, depression or impotence.

Which gland is responsible for ejaculation?

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.

What is the glans?

The glans: This is the cone-shaped end of the penis. The glans, which is also called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision.

What is the fluid that makes up the majority of a man's ejaculatory fluid?

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.

What is the role of LH in testosterone production?

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.

Why do testicles move toward the body?

Muscles in the wall of the scrotum can move the testicles toward the body for warmth , or further away to decrease the temperature.

What are the three hormones that are involved in the male reproductive system?

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), ...

Which muscular tube carries mature sperm from the epididymis to the urethra prior?

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.

What are the conditions that affect the male reproductive system?

Common Conditions of the Male Reproductive System. Several urological conditions can affect the male reproductive system, including: Hypospadias: A condition that is present at birth (congenital), in which the urethra opens anywhere other than the tip of the penis.

What are the reproductive systems of men?

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.

What is the ejaculatory duct?

Ejaculatory ducts: These are formed by the fusion of the vas deferens and the seminal vesicles (see below). The ejaculatory ducts empty into the urethra. Urethra: The urethra is the tube that carries urine from the bladder to outside of the body.

What is the job of the epididymis?

It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity , since the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens.

How many testes do men have?

Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing sperm cells. The internal organs of the male reproductive system, also called accessory organs, ...

Where does the vas deferens go?

Vas deferens: The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the body, in preparation for ejaculation.

What are the internal organs of the male reproductive system?

The internal organs of the male reproductive system, also called accessory organs, include the following: Epididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, ...

What is testosterone responsible for?

Testosterone is responsible for the development of male characteristics, including muscle mass and strength, fat distribution, bone mass, facial hair growth, voice change, and sex drive. Share on Facebook Share on Twitter Share on Pinterest Email Print.

What is the sac of skin that hangs behind and below the penis?

Scrotum: This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum acts as a "climate control system" for the testes.

What are the structures of the male reproductive system?

Differentiate between the structures of the male reproductive system including the tetes, epididymis, spermatic cords, ductus deferens, ejaculatory duct and urethra.

What is the purpose of the ampulla?

Both the ejaculatory duct and the urethra pass by three accessory glands. Each gland secretes fluids that will nourish and protect sperm as it passes through the male reproductive tract.

What is the tube that connects the testes and the epididymis?

Each epididymis connects to a larger tube called the ductus deferens, also known as the vas deferens, which travels from the epididymis up into the body of the male. Now, running alongside the ductus deferens are arteries and veins, and together these make up paired structures called spermatic cords. It is these cords that connect the testes and the epididymis to the body. Without these connections, there would be no flow of blood, sperm and other fluids to and from the testes.

How many feet is the epididymis?

Amazingly, the epididymis is a coiled tubule that, if unwound, would measure about 23 feet! This 23 feet of coiled tube can be divided into 3 parts: the head, the body and the tail. The head of the epididymis is closest to the top of the testes and accepts the immature sperm that is leaving the testes.

Why do sperm need to be stored?

So it wouldn't be very practical to make the sperm as needed, would it? That's why males have developed places along their reproductive tract to store the sperm that are ready. Ready for what? Well, ready for reproduction! That is where our next set of structures comes in.

Which part of the penis stores sperm?

The epididymis matures the sperm and passes it along to the ductus deferens. The ductus deferens store the sperm in the ampulla and transport it into the ejaculatory duct. The ejaculatory duct merges into the urethra, which exits at the tip of the penis.

Where does the ductus deferens begin?

The ductus deferens begins here, at the tail of the epididymis. It then travels up into the abdominal cavity, wraps around the urinary bladder and then curves back down to start its descent behind (or posterior to) the bladder. As it begins its descent, it expands into a portion called the ampulla. The ampulla is part of the ductus deferens and is where most of the sperm is going to be stored until needed.

How Does Male Reproductive System Works?

The male reproductive organs work together in order to produce and then release sperm into the female`s reproductive system during a sexual contact. The male sex organs produce sex hormones as well; these help a boy turn into a sexually adult human being during puberty.

What are the different types of urethra?

There are 3 segments described: 1 The prostatic urethra crosses the prostate from the base to the top and presents a sagittal ridge on the posterior wall known as the urethral crest. 2 The membranous urethra stretches between the prostate`s tip and the penis`s spongy body. It has an anterior report with the vezico-prostatic vein plexus and the transverse ligament of the perineum. 3 The spongy urethra has 2 dilations.
