What Is Reproduction?
Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive.
In the human reproductive process, two kinds of sex cells, or gametes (pronounced: GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (pronounced: ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.
The male reproductive system and the female reproductive system both are needed for reproduction.
Humans, like other organisms, pass some characteristics of themselves to the next generation. We do this through our genes, the special carriers of human traits. The genes that parents pass along are what make their children similar to others in their family, but also what make each child unique. These genes come from the male's sperm and the female's egg.
What Is the Male Reproductive System?
The male has reproductive organs, or genitals, that are both inside and outside the pelvis. The male genitals include:
the testicles (pronounced: TESS-tih-kulz)
the duct system, which is made up of the epididymis and the vas deferens
the accessory glands, which include the seminal vesicles and prostate gland
In a guy who has reached sexual maturity, the two oval-shaped testicles, or testes (pronounced: TESS-teez) make and store millions of tiny sperm cells.
The testicles are also part of the endocrine system because they make hormones, including testosterone (pronounced: tess-TOSS-tuh-rone). Testosterone is a major part of puberty in guys. As a guy makes his way through puberty, his testicles produce more and more of it. Testosterone is the hormone that causes boys to develop deeper voices, bigger muscles, and body and facial hair. It also stimulates the production of sperm.
Alongside the testicles are the epididymis and the vas deferens, which transport sperm. The epididymis (pronounced: ep-uh-DID-uh-miss) and the testicles hang in a pouch-like structure outside the pelvis called the scrotum. This bag of skin helps to regulate the temperature of testicles, which need to be kept cooler than body temperature to produce sperm. The scrotum changes size to maintain the right temperature. When the body is cold, the scrotum shrinks and becomes tighter to hold in body heat. When it's warm, it gets larger and floppier to get rid of extra heat. This happens without a guy ever having to think about it. The brain and the nervous system give the scrotum the cue to change size.
The accessory glands, including the seminal vesicles and the prostate gland, provide fluids that lubricate the duct system and nourish the sperm. The urethra (pronounced: yoo-REE-thruh) is the channel that carries the sperm (in fluid called semen) to the outside of the body through the penis. The urethra is also part of the urinary system because it is also the channel through which pee passes as it leaves the bladder and exits the body.
The penis is actually made up of two parts: the shaft and the glans. The shaft is the main part of the penis and the glans is the tip (sometimes called the head). At the end of the glans is a small slit or opening, which is where semen and pee exit the body through the urethra. The inside of the penis is made of a spongy tissue that can expand and contract.
The Male Reproductive System
Like other living things, human beings reproduce. It's what keeps the population going. In humans, the male and female reproductive systems work together to make a baby.

All boys are born with a foreskin, a fold of skin at the end of the penis covering the glans. Some boys are circumcised, which means that a doctor or clergy member cuts away the foreskin. Circumcision is usually done during a baby boy's first few days of life. It's not medically necessary, but parents who choose to have their sons circumcised often do so based on religious beliefs, concerns about hygiene, or cultural or social reasons. Guys who have circumcised penises and those who don't are no different: All penises work and feel the same, regardless of whether the foreskin has been removed.
How Does the Male Reproductive System Work?
The male reproductive system:
makes semen (pronounced: SEE-mun)
releases semen into the reproductive system of the female during sexual intercourse
produces sex hormones, which help a boy develop into a sexually mature man during puberty
Male Reproductive System: Structure & Function
The male reproductive system is made up of internal and external organs, including the penis, testicles and urethra. This system is responsible for sexual function and urination.
Male Reproductive System
The male reproductive system is mostly located outside of the body. 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.
Male Reproductive Anatomy
What’s the male reproductive system?
The male reproductive system includes a group of organs that make up a man’s reproductive and urinary system. These organs do the following jobs within your body:
They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around sperm).
They discharge sperm into the female reproductive tract.
They produce and secrete male sex hormones.
The male reproductive system is made up of internal (inside your body) and external (outside your body) parts. Together, these organs help you urinate (rid your body of liquid waste materials), have sexual intercourse and make children.

How does the male reproductive system function?
The entire male reproductive system is dependent on hormones. These are chemicals that stimulate or regulate the activity of your cells or organs. The primary hormones involved in the functioning of the male reproductive system are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone.
FSH and LH are produced by the pituitary gland. It’s located at the base of your brain and it’s responsible for many functions in your body. 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.
What are the external male reproductive structures?
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.Penis
The penis is the male organ for sexual intercourse. It has three parts:The root: This is the part of the penis that attaches to the wall of your abdomen.The body or shaft: Shaped like a tube or cylinder, the body of the penis is made up of three internal chambers. Inside these chambers there’s a special, sponge-like erectile tissue that contains thousands of large spaces that fill with blood when you’re sexually aroused. As the penis fills with blood, it becomes rigid and erect, which allows for penetration during sex. The skin of the penis is loose and elastic, allowing for changes in penis size during an erection.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.
The opening of the urethra — the tube that transports both semen and urine out of the body — is located at the tip of the glans penis. The penis also contains many sensitive nerve endings.
Semen, which contains sperm, is expelled (ejaculated) through the end of the penis when a man reaches sexual climax (orgasm). When the penis is erect, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.Scrotum
The scrotum is the loose pouch-like sac of skin that hangs behind the penis. It holds the testicles (also called testes), as well as many nerves and blood vessels. 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. Special muscles in the wall of the scrotum allow it to contract (tighten) and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.Testicles (testes)
The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. 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.Epididymis
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. During sexual arousal, contractions force the sperm into the vas deferens.
What are the internal male reproductive organs?
You have several internal organs — also called accessory organs — that play a big part in the male reproductive system. These organs include:

Ovaries Produces and develops eggs
Fallopian tubes (oviducts) Transports egg to uterus, acts as site of fertilization
Uterus Supports a developing embryo
Cervix Allows passage between the uterus and the vagina
Vagina Receives penis during intercourse, acts as birth canal, passes menstrual flow
Breasts Produce and deliver milk
During puberty, the hypothalamus signals the pituitary gland to produce two hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). In females, FSH and LH stimulate the ovaries to produce the female sex hormones, estrogen and progesterone. This results in the development of secondary sex characteristics (such as breasts), and causes the ovaries to begin producing mature eggs.
Egg release (ovulation) occurs approximately every 28 days, and is part of a larger process called the menstrual cycle. If an egg is fertilized after ovulation, it attaches to the wall of the uterus and embryonic development begins.
If an egg is not fertilized (or a fertilized egg does not attach to the wall of the uterus), the egg and the lining of the uterus are discharged from the body.

Testes Produce sperm and male hormones
Scrotum Supports testes and regulates their temperature
Seminal vesicle Contribute fluids to semen production
Prostate gland Secretes prostate fluid (component of semen), aids in ejaculation
Epididymis Stores mature sperm
Vas deferens Transports sperm from epididymis
Penis Transfers sperm into female
Puberty begins the same way in males as it does in females: the hypothalamus signals the pituitary gland to produce FSH and LH.
In males, LH stimulates the testes to produce testosterone, and with FSH, causes sperm development to occur. Testosterone is also responsible for the development of secondary male sex characteristics, such as a deepened voice and growth of body hair.
Common mistakes and misconceptionsFertilization occurs in the fallopian tube (oviduct) of the female reproductive system. Once fertilized, the egg attaches to the lining of the uterus. It becomes a ball of cells over time, then develops in the uterus of the female to become a baby.Only females are born with reproductive sex cells. Females are born with immature eggs already in their ovaries. When puberty occurs, the eggs mature and are released by the ovaries. Males only produce sperm after reaching puberty.Females do not urinate through the vagina. In men, both semen and urine pass through the urethra, a passageway that terminates at the end of the penis. Females urinate through a urethra as well, but it is not connected to their vaginal opening. The female urethra is located above the vagina and urine may pass over or around the opening, but the two passageways are not connected.

I have certain doubt regarding female reproductive system
(1) There are two ovaries in female reproductive system and in video lecture sir said there is only one egg is produced in female so which ovary produce egg?
(2) There are two fallopian tubes in which one ferilization occure?
(3)how the sperm reaches from the vagina to fallopian tube in the female reproductive system diagram it is not clear
kindly help me • chaniru ratnaweera 3 years ago
Posted 3 years ago. Direct link to chaniru ratnaweera's post “1)it depends on the readi...”
1)it depends on the readiness of each ovary to release the egg so when one ovary is still building the egg the other ovary releases the egg
2)any (depending on what direction sperm cells swim)
